Serum albumin measurements are used in the monitoring and treatment of numerous diseases involving those related to nutrition and pathology particularly in the liver and kidney. Serum albumin is valuable when following response to therapy where improvement in the serum albumin level is the best sign of successful medical treatment. There may be a loss of albumin in the gastrointestinal tract, in the urine secondary to renal damage or direct loss of albumin through the skin. More than 50% of patients with gluten enteropathy have depressed albumin. The only cause of increased albumin is dehydration; there is no naturally occurring hyperalbuminemia

Description: An Alkaline Phosphatase test or ALP is a blood test that is used to screen for and monitor liver disease, bone disorders, and gallbladder disease.

Also Known As: ALP Test, Alk Phos Test, Alkp Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is an Alkaline Phosphatase test ordered?

An ALP test may be requested as a standard laboratory test, frequently in conjunction with a liver panel of further assays. When a person exhibits signs of a liver or bone issue, it is frequently requested in conjunction with a number of additional tests.

What does an Alkaline Phosphatase test check for?

An enzyme called alkaline phosphatase is present in many bodily tissues. The cells that make up bone and the liver have the highest quantities of ALP. Liver illness or bone diseases are the most frequent causes of high blood levels of ALP. The blood's concentration of ALP is determined by this test.

ALP is located in the liver on the margins of cells that converge to form bile ducts, which are minuscule tubes that transport bile from the liver to the bowels, where it is required to aid in the digestion of dietary fat. Osteoblasts, specialized cells involved in bone production, are responsible for producing ALP in bone. Isoenzymes, which are produced in unique forms by each type of tissue, are ALP.

For instance, when one or more bile ducts are obstructed, ALP blood levels may significantly rise. Gallbladder inflammation or gallstones may be the cause of this. Blood ALP levels rise slightly more subtly in cirrhosis, liver cancer, hepatitis, and when liver-toxic medications are used.

Increased ALP levels can result from any condition that promotes excessive bone growth, including bone diseases like Paget's disease. Because their bones are still growing, children and adolescents often have higher blood ALP levels. Because of this, the ALP test needs to be interpreted differently for children and adults.

It is feasible to distinguish between the various ALP forms generated by various bodily tissues. A test may be run to identify which isoenzyme is elevated in the blood if it is unclear from clinical signs and symptoms whether the cause of a high ALP test result is liver or bone illness.

Lab tests often ordered with an Alkaline Phosphatase test:

  • AST
  • ALT
  • GGT
  • Bilirubin
  • Comprehensive Metabolic Panel
  • Hepatic Function Panel
  • Alkaline Phosphatase Isoenzymes

Conditions where an Alkaline Phosphatase test is recommended:

  • Lier Disease
  • Hepatitis
  • Cirrhosis
  • Jaundice
  • Osteoporosis
  • Paget’s Disease
  • Vitamin D Deficiency

How does my health care provider use an Alkaline Phosphatase test?

Using the alkaline phosphatase test, liver disease and bone diseases can be found.

Damaged liver cells produce more ALP into the blood under situations that harm the liver. Because ALP levels are particularly high at the margins of the cells that unite to form bile ducts, this test is frequently used to identify obstructed bile ducts. Blood levels of ALP are frequently high when one or more of them are blocked, such as by a tumor.

ALP levels in the blood can be impacted by any illness or disease that hinders bone development or increases bone cell activity. For instance, an ALP test may be used to identify tumors that have metastasized to the bones or to identify Paget's disease, a condition that results in deformed bones. This examination could occasionally be used to track the progress of patients being treated for Paget's disease or other bone disorders such vitamin D insufficiency.

Tests for the ALP isoenzyme may be performed to identify the cause if ALP readings are elevated but it is unclear whether this is related to liver or bone illness. To distinguish between liver and bone illness, one may additionally perform a GGT test and/or a test for 5'-nucleotidase. The levels of GGT and 5'-nucleotidase are elevated in liver illness but not in disorders of the bones.

What do my Alkaline Phosphatase test results mean?

High ALP typically indicates the presence of a disease that increases bone cell activity or liver damage.

The liver is typically where the elevated ALP is coming from if other liver tests, such as bilirubin, aspartate aminotransferase, or alanine aminotransferase, are also high. The high ALP is probably the result of liver illness if GGT or 5-nucleotidase levels are also elevated. If one of these two tests comes out normal, a bone issue is probably to blame for the high ALP. The ALP is typically coming from bone if calcium and/or phosphorus readings are abnormal.

A test for ALP isoenzymes may be required to differentiate between bone and liver ALP if it is unclear from signs and symptoms or other regular testing whether the high ALP is from the liver or bone.

ALP test findings are typically analyzed alongside those of other liver disease testing. ALP is commonly significantly less increased than AST and ALT in several types of liver illness, such as hepatitis. ALP and bilirubin may increase substantially higher than AST or ALT when the bile ducts are obstructed. ALP levels in liver cancer may also be higher.

ALP may be elevated in some bone illnesses, such as Paget's disease, which causes enlarged and misshapen bones, or in some cancers that extend to the bone.

ALP levels will eventually drop or return to normal if Paget's disease is successfully treated in a patient. ALP levels should fall if someone with liver or bone cancer responds to therapy.

Other illnesses include Hodgkin's lymphoma, congestive heart failure, ulcerative colitis, and specific bacterial infections can cause moderately high ALP.

ALP levels may briefly drop after cardiac bypass surgery or blood transfusions. Levels may drop as a result of a zinc deficiency. Hypophosphatasia, a rare genetic bone metabolism condition, can result in extremely low levels of ALP that persist for a long time. Wilson disease, protein insufficiency, and malnutrition are further potential reasons of low ALP.

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.


Description: An ALT test is a blood test that is used to screen for and diagnose liver disease.

Also Known As: Alanine Aminotransferase Test, Alanine Transaminase Test, GPT Test, SGPT Test, Serum Glutamic Pyruvic Transaminase Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is an Alanine Transaminase test ordered?

When a person undergoes a standard health examination, ALT may be ordered as part of a full metabolic panel.

When a person has signs and symptoms of a liver problem, a healthcare provider will usually prescribe an ALT test.

Because many people with minor liver damage have no signs or symptoms, ALT may be ordered alone or in combination with other tests for persons who are at an elevated risk for liver disease. With modest liver injury, ALT levels will rise even if there are no other symptoms.

ALT may be ordered on a frequent basis during the course of treatment to establish whether the medication is effective when it is used to monitor the treatment of persons with liver disease.

What does an Alanine Transaminase blood test check for?

Alanine aminotransferase is an enzyme found mostly in liver and kidney cells. It's also found in much lesser concentrations in the heart and muscles. This test determines the amount of ALT in your blood.

The enzyme ALT converts alanine, a protein amino acid, into pyruvate, an important intermediary in cellular energy production. ALT levels in the blood are low in healthy people. ALT is released into the bloodstream when the liver is injured, frequently before more evident indications of liver injury, such as jaundice, appear. As a result, ALT is a useful test for detecting liver disease early on.

The liver is a critical organ positioned directly behind the rib cage on the upper right side of the abdomen. It is engaged in a variety of vital bodily functions. The liver aids in the digestion of nutrients, creates bile to aid in fat digestion, produces a variety of essential proteins such as blood clotting factors and albumin, and breaks down potentially hazardous compounds into safe substances that the body may utilize or discard.

Damage to liver cells can be caused by a variety of factors, resulting in an elevation in ALT. The test is most useful for detecting damage caused by hepatitis or medications or other toxins that are harmful to the liver.

As part of a liver panel, ALT is frequently tested alongside aspartate aminotransferase, another liver enzyme. When the liver is injured, both ALT and AST levels rise, albeit ALT is more specific for the liver and may be the only one to rise in some circumstances. An AST/ALT ratio can be used to help distinguish between different types of liver injury and their severity, as well as to distinguish liver injury from heart or muscle damage.

Lab tests often ordered with an Alanine Transaminase test:

  • AST
  • ALP
  • GGT
  • Bilirubin
  • Liver Panel
  • Comprehensive Metabolic Panel
  • Albumin
  • Total Protein
  • Prothrombin Time
  • Hepatitis Panel General

Conditions where a an Alanine Transaminase test is recommended:

  • Liver Disease
  • Hepatitis
  • Jaundice
  • Cirrhosis
  • Alcoholism
  • Wilson Disease
  • Hemochromatosis

How does my health care provider use an Alanine Transaminase test?

The alanine aminotransferase test is commonly used to diagnose liver damage. It's frequently ordered as part of a liver panel or complete metabolic panel with aspartate aminotransferase to screen for and/or diagnose liver disease.

ALT is an enzyme found mostly in liver and kidney cells. ALT is released into the bloodstream when the liver is injured. As a result, ALT is a useful test for detecting liver disease early on.

Although ALT is more specific to the liver than AST, they are both considered to be two of the most significant tests for detecting liver impairment. When AST is directly compared to ALT, an AST/ALT ratio is calculated. This ratio can assist distinguish between different types of liver disease and identify cardiac or muscle harm.

To assess which type of liver illness is present, ALT values are frequently matched to the results of other tests such as alkaline phosphatase, total protein, and bilirubin.

ALT is frequently requested to monitor the therapy of people with liver disease to evaluate if it is effective, and it can be ordered alone or in combination with other tests.

What do my ALT test results mean?

A low ALT level in the blood is normal and anticipated. The most prevalent cause of ALT levels that are higher than normal is liver disease.

Acute hepatitis and viral infections are the most common causes of very elevated ALT values. ALT levels are normally elevated for 1-2 months after acute hepatitis, but they might take up to 3-6 months to return to normal. ALT levels may also be significantly raised as a result of exposure to liver-toxic medications or other chemicals, or in situations that produce reduced blood flow (ischemia) to the liver.

In chronic hepatitis, ALT levels are frequently less than four times normal. Because ALT levels in this scenario regularly fluctuate between normal and slightly elevated, the test may be ordered frequently to observe if a trend emerges. Other reasons of mild ALT elevations include bile duct obstruction, cirrhosis, heart damage, alcohol addiction, and liver cancers.

ALT is frequently used in conjunction with an AST test or as part of a liver panel. See the Liver Panel article for more information on ALT values in relation to other liver tests.

The ALT level is usually greater than the AST level in most forms of liver disorders, and the AST/ALT ratio is low. There are a few exceptions: in alcoholic hepatitis, cirrhosis, and heart or muscle injury, the AST/ALT ratio is frequently more than 1, and it may be greater than 1 for a day or two after the onset of acute hepatitis.

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.


Description: An AST blood test is a test that is used to screen for and diagnose liver disease.

Also Known As: Aspartate Aminotransferase Test, Serum Glutamic-Oxaloacetic Transaminase Test, SGOT Test Transaminase, Serum AST Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is an Aspartate Aminotransferase test ordered?

When someone undergoes a standard health examination, an AST test may be requested as part of a full metabolic panel.

When a person exhibits indications and symptoms of a liver problem, an AST test may be ordered along with numerous other tests.

Because many persons with minor liver damage have no signs or symptoms, AST may be ordered alone or in combination with other tests for people who are at an elevated risk for liver disease.

When AST is used to evaluate the effectiveness of treatment for people with liver disease, it may be ordered on a frequent basis during the course of treatment.

What does an Aspartate Aminotransferase blood test check for?

Aspartate aminotransferase is an enzyme found in cells all over the body, but especially in the heart and liver, as well as the kidneys and muscles to a lesser amount. AST levels in the blood are typically low in healthy people. AST is released into the bloodstream when liver or muscle cells are damaged. As a result, AST can be used to detect or monitor liver disease.

The liver is a critical organ found directly behind the rib cage in the upper right side of the abdomen. It is engaged in a variety of vital bodily functions. The liver aids in the digestion of nutrients, creates bile to aid in fat digestion, manufactures numerous vital proteins such as blood clotting factors, and breaks down potentially hazardous compounds into safe substances that the body may utilize or expel.

A variety of disorders can harm liver cells and cause AST levels to rise. The test is most effective in detecting liver damage caused by hepatitis, liver-toxic medications, cirrhosis, or alcoholism. AST, on the other hand, is not particular to the liver and can be elevated in diseases affecting other organs.

Alanine aminotransferase testing is frequently combined with an AST test. When the liver is injured, both of these enzymes become high in the bloodstream. A computed AST/ALT ratio can help distinguish between different types of liver injury and determine whether elevated levels are due to something else, such as a heart or muscle injury.

Lab tests often ordered with an Aspartate Aminotransferase test:

  • GGT
  • ALT
  • ALP
  • Bilirubin
  • Hepatic Function Panel
  • Comprehensive Metabolic Panel (CMP)
  • Albumin
  • Total Protein

Conditions where an Aspartate Aminotransferase test is recommended:

  • Liver Disease
  • Hepatitis
  • Jaundice
  • Alcoholism
  • Cirrhosis
  • Wilson Disease
  • Hemochromatosis

How does my health care provider use an Aspartate Aminotransferase test?

The aspartate aminotransferase blood test is commonly used to identify liver disease. It is frequently ordered in conjunction with alanine aminotransferase, another liver enzyme, or as part of a liver panel or comprehensive metabolic panel to screen for and/or diagnose liver problems.

Although ALT is more specific for the liver than AST and is more usually elevated than AST, both are regarded to be two of the most significant tests for detecting liver impairment. When AST is directly compared to ALT, an AST/ALT ratio is calculated. This ratio can be used to differentiate between different types of liver disease and hepatic harm from heart or muscle damage.

To assess which type of liver illness is present, AST levels are frequently compared to the results of other tests such as alkaline phosphatase, total protein, and bilirubin.

AST is frequently evaluated to monitor the treatment of people with liver disease, and it can be ordered alone or in combination with other tests.

AST is sometimes used to monitor persons who are receiving potentially hazardous drugs for the liver. If the person's AST levels rise, he or she may be moved to another medicine.

What do my AST test results mean?

Low AST levels in the blood are typical and anticipated.

Acute hepatitis and viral infections are the most common causes of very high AST values. AST values are normally elevated for 1-2 months after acute hepatitis, but they might take up to 3-6 months to recover to normal. AST levels can also be significantly high as a result of exposure to liver-toxic medications or other chemicals, as well as situations that produce reduced blood supply to the liver.

AST values are usually lower in chronic hepatitis, generally less than 4 times normal, and are more likely to be normal than ALT levels. With chronic hepatitis, AST levels typically fluctuate between normal and slightly elevated, so the test may be ordered repeatedly to detect the pattern. Other illnesses of the liver, particularly when the bile ducts are clogged, as well as cirrhosis and certain malignancies of the liver, can cause moderate increases. AST can also rise after a heart attack or a muscular damage, although to a far higher extent than ALT.

The AST test is frequently done in conjunction with the ALT test or as part of a liver panel. See the Liver Panel article for more information on AST values in relation to other liver tests.

The ALT level is usually greater than the AST level in most kinds of liver disease, and the AST/ALT ratio is low. There are a few exceptions: in alcoholic hepatitis, cirrhosis, hepatitis C virus-related chronic liver disease, and the first day or two of acute hepatitis or injury from bile duct obstruction, the AST/ALT ratio is frequently elevated. AST levels are generally substantially higher than ALT after cardiac or muscle injury, and they tend to stay higher than ALT for longer than they do after liver injury.

Measurement of the levels of bilirubin is used in the diagnosis and treatment of liver, hemolytic, hematologic, and metabolic disorders, including hepatitis and gall bladder obstruction. The assessment of direct bilirubin is helpful in the differentiation of hepatic disorders. The increase in total bilirubin associated with obstructive jaundice is primarily due to the direct (conjugated) fraction. Both direct and indirect bilirubin are increased in the serum with hepatitis.

Description: Bilirubin Fractionated is a blood test that is used to screen for or monitor liver disorders, hemolytic anemia, and neonatal jaundice.

Also Known As: Total Bilirubin Test, TBIL Test, Neonatal Bilirubin Test, Direct Bilirubin Test, Conjugated Bilirubin Test, Indirect Bilirubin Test, Unconjugated Bilirubin Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is a Bilirubin, Fractionated test ordered?

When someone shows evidence of abnormal liver function, a doctor will usually request a bilirubin test along with other laboratory tests. A bilirubin test may be ordered when a patient:

  • Evidence of jaundice is visible.
  • Has a history of excessive alcohol consumption
  • Has a possible drug toxicity
  • Has been exposed to viruses that cause hepatitis

Other signs and symptoms to look out for include:

  • Urine with a dark amber tint.
  • Nausea/vomiting
  • Swelling and/or pain in the abdomen
  • Fatigue and malaise which are common symptoms of chronic liver disease.

In babies with jaundice, measuring and monitoring bilirubin is considered routine medical therapy.

When someone is suspected of hemolytic anemia as a cause of anemia, bilirubin tests may be ordered. In this instance, it's frequently ordered in conjunction with other hemolysis-related tests such a complete blood count, reticulocyte count, haptoglobin, and LDH.

What does a Bilirubin, Fractionated blood test check for?

Bilirubin is an orange-yellow pigment that is largely formed as a byproduct of heme degradation. Heme is a component of hemoglobin, a red blood cell protein. Bilirubin is eventually digested by the liver, which allows it to be excreted from the body. This test assesses a person's liver function or aids in the diagnosis of anemias caused by RBC destruction by measuring the quantity of bilirubin in their blood.

After roughly 120 days in circulation, RBCs generally disintegrate. Heme is transformed to bilirubin as it is released from hemoglobin. Unconjugated bilirubin is another name for this type of bilirubin. Proteins transport unconjugated bilirubin to the liver, where sugars are linked to bilirubin to produce conjugated bilirubin. Conjugated bilirubin enters the bile and travels from the liver to the small intestines, where bacteria break it down further before it is excreted in the stool. As a result, bilirubin breakdown products give stool its distinctive brown hue.

A normal, healthy human produces a tiny quantity of bilirubin each day. The majority of bilirubin comes from damaged or degraded RBCs, with the rest coming from bone marrow or the liver. Small amounts of unconjugated bilirubin are normally discharged into the bloodstream, but there is almost no conjugated bilirubin. Laboratory tests can measure or estimate both types, and a total bilirubin result can be presented as well.

A person may appear jaundiced, with yellowing of the skin and/or whites of the eyes, if the bilirubin level in their blood rises. The pattern of bilirubin test results can provide information to the health care provider about the ailment that may be present. When there is an exceptional quantity of RBC destruction or when the liver is unable to handle bilirubin, unconjugated bilirubin levels may rise. Conversely, conjugated bilirubin levels can rise when the liver can process bilirubin but not transmit the conjugated bilirubin to the bile for elimination; this is most commonly caused by acute hepatitis or bile duct blockage.

In the first few days after birth, increased total and unconjugated bilirubin levels are fairly common in infants. This condition is known as "physiologic jaundice of the newborn," and it develops when the liver of a newborn is not yet mature enough to handle bilirubin. Physiologic jaundice in newborns usually goes away after a few days. RBCs may be damaged in newborn hemolytic illness due to blood incompatibility between the infant and the mother; in these circumstances, treatment may be necessary since large amounts of unconjugated bilirubin might harm the newborn's brain.

Increased total and conjugated bilirubin levels in infants can be caused by biliary atresia, an uncommon but life-threatening congenital disease. To avoid catastrophic liver damage that may necessitate liver transplantation during the first few years of life, this problem must be rapidly recognized and treated, usually with surgery. Despite early surgical therapy, some children may require liver transplants.

Lab tests often ordered with a Bilirubin, Fractionated test:

Commonly Asked Questions:

How does my health care provider use a Bilirubin, Fractionated test?

A bilirubin test is used to detect an abnormally high quantity of the substance in the blood. It can be used to figure out what's causing your jaundice and/or diagnose illnesses like liver disease, hemolytic anemia, and bile duct blockage.

Bilirubin is an orange-yellow pigment that is largely formed as a byproduct of heme degradation. Heme is a component of hemoglobin, a red blood cell protein. Bilirubin is eventually digested by the liver, which allows it to be excreted from the body. An increased blood level can be caused by any disorder that speeds up the breakdown of RBCs or impairs the processing and elimination of bilirubin.

Laboratory testing can measure or estimate two types of bilirubin:

Unconjugated bilirubin—unconjugated bilirubin is formed when heme is released from hemoglobin. Proteins transport it to the liver. Small levels of the substance may be found in the blood.

Sugars are attached to bilirubin in the liver, resulting in conjugated bilirubin. It enters the bile and travels from the liver to the small intestines before being excreted in the feces. In normal circumstances, there is no conjugated bilirubin in the blood.

A chemical test is usually done to determine the total bilirubin level first. If the total bilirubin level rises, a second chemical test can be used to detect water-soluble forms of bilirubin, known as "direct" bilirubin. The amount of conjugated bilirubin present can be estimated using the direct bilirubin test. The "indirect" amount of unconjugated bilirubin can be estimated by subtracting the direct bilirubin level from the total bilirubin level. The pattern of bilirubin test results can provide information to the healthcare professional about the ailment that may be present.

Bilirubin is measured in adults and older children to:

  • Diagnose and/or monitor liver and bile duct disorders.
  • Evaluate patients with hemolytic anemia
  • Distinguish between the causes of jaundice in babies.

Only unconjugated bilirubin is raised in both physiologic jaundice and hemolytic illness of the infant.

Damage to the newborn's liver from neonatal hepatitis and biliary atresia will also raise conjugated bilirubin concentrations, which is generally the first indication that one of these less common disorders is present.

Because excessive unconjugated bilirubin harms growing brain cells, it is critical to detect and treat an increased amount of bilirubin in a newborn. Mental retardation, learning and developmental impairments, hearing loss, eye movement disorders, and mortality are all possible outcomes of this damage.

What do my bilirubin test results mean?

In adults and children, increased total bilirubin, primarily unconjugated bilirubin, could be caused by:

  • Hemolytic or pernicious anemia are two types of anemia.
  • Reaction to a transfusion
  • Cirrhosis
  • Gilbert syndrome

When conjugated bilirubin levels are higher than unconjugated bilirubin levels, there is usually a problem with bilirubin removal by the liver cells. This can be caused by a variety of factors, including:

  • Hepatitis caused by a virus
  • Reactions to drugs
  • Alcoholic hepatitis

When the bile ducts are blocked, conjugated bilirubin is raised more than unconjugated bilirubin. This can happen, for example, when:

  • In the bile ducts, there are gallstones.
  • Damaging of the bile ducts due to tumors

Increased bilirubin levels can also be caused by rare hereditary illnesses that involve aberrant bilirubin metabolism, such as Rotor, Dubin-Johnson, and Crigler-Najjar syndromes.

Low bilirubin levels are usually not a cause for worry and are not monitored.

A newborn's high bilirubin level may be transient and diminish within a few days to two weeks. However, if the bilirubin level exceeds a crucial threshold or rises rapidly, the cause must be investigated so that appropriate treatment can be started. Increased bilirubin levels can be caused by the rapid breakdown of red blood cells as a result of:

  • Incompatibility of the mother's blood type with that of her child
  • Infections that are present at birth
  • oxygen deficiency
  • Liver disease

Only unconjugated bilirubin is elevated in most of these disorders. In the rare disorders of biliary atresia and newborn hepatitis, increased conjugated bilirubin is found. To avoid liver damage, biliary atresia necessitates surgical surgery.

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.


Description: A CBC or Complete Blood Count with Differential and Platelets test is a blood test that measures many important features of your blood’s red and white blood cells and platelets. A Complete Blood Count can be used to evaluate your overall health and detect a wide variety of conditions such as infection, anemia, and leukemia. It also looks at other important aspects of your blood health such as hemoglobin, which carries oxygen. 

Also Known As: CBC test, Complete Blood Count Test, Total Blood Count Test, CBC with Differential and Platelets test, Hemogram test  

Collection Method: Blood Draw 

Specimen Type: Whole Blood 

Test Preparation: No preparation required 

When is a Complete Blood Count test ordered?  

The complete blood count (CBC) is an extremely common test. When people go to the doctor for a standard checkup or blood work, they often get a CBC. Suppose a person is healthy and their results are within normal ranges. In that case, they may not need another CBC unless their health condition changes, or their healthcare professional believes it is necessary. 

When a person exhibits a variety of signs and symptoms that could be connected to blood cell abnormalities, a CBC may be done. A health practitioner may request a CBC to help diagnose and determine the severity of lethargy or weakness, as well as infection, inflammation, bruises, or bleeding. 

When a person is diagnosed with a disease that affects blood cells, a CBC is frequently done regularly to keep track of their progress. Similarly, if someone is being treated for a blood condition, a CBC may be performed on a regular basis to see if the treatment is working. 

Chemotherapy, for example, can influence the generation of cells in the bone marrow. Some drugs can lower WBC counts in the long run. To monitor various medication regimens, a CBC may be required on a regular basis. 

What does a Complete Blood Count test check for? 

The complete blood count (CBC) is a blood test that determines the number of cells in circulation. White blood cells (WBCs), red blood cells (RBCs), and platelets (PLTs) are three types of cells suspended in a fluid called plasma. They are largely created and matured in the bone marrow and are released into the bloodstream when needed under normal circumstances. 

A CBC is mainly performed with an automated machine that measures a variety of factors, including the number of cells present in a person's blood sample. The findings of a CBC can reveal not only the quantity of different cell types but also the physical properties of some of the cells. 

Significant differences in one or more blood cell populations may suggest the presence of one or more diseases. Other tests are frequently performed to assist in determining the reason for aberrant results. This frequently necessitates visual confirmation via a microscope examination of a blood smear. A skilled laboratory technician can assess the appearance and physical features of blood cells, such as size, shape, and color, and note any anomalies. Any extra information is taken note of and communicated to the healthcare provider. This information provides the health care provider with further information about the cause of abnormal CBC results. 

The CBC focuses on three different types of cells: 

WBCs (White Blood Cells) 

The body uses five different types of WBCs, also known as leukocytes, to keep itself healthy and battle infections and other types of harm. The five different leukocytes are eosinophiles, lymphocytes, neutrophiles, basophils, and monocytes. They are found in relatively steady numbers in the blood. Depending on what is going on in the body, these values may momentarily rise or fall. An infection, for example, can cause the body to manufacture more neutrophils in order to combat bacterial infection. The amount of eosinophils in the body may increase as a result of allergies. A viral infection may cause an increase in lymphocyte production. Abnormal (immature or mature) white cells multiply fast in certain illness situations, such as leukemia, raising the WBC count. 

RBCs (Red Blood Cells) 

The bone marrow produces red blood cells, also known as erythrocytes, which are transferred into the bloodstream after maturing. Hemoglobin, a protein that distributes oxygen throughout the body, is found in these cells. Because RBCs have a 120-day lifespan, the bone marrow must constantly manufacture new RBCs to replace those that have aged and disintegrated or have been lost due to hemorrhage. A variety of diseases, including those that cause severe bleeding, can alter the creation of new RBCs and their longevity. 

The CBC measures the number of RBCs and hemoglobin in the blood, as well as the proportion of RBCs in the blood (hematocrit), and if the RBC population appears to be normal. RBCs are generally homogeneous in size and shape, with only minor differences; however, considerable variances can arise in illnesses including vitamin B12 and folate inadequacy, iron deficiency, and a range of other ailments. Anemia occurs when the concentration of red blood cells and/or the amount of hemoglobin in the blood falls below normal, resulting in symptoms such as weariness and weakness. In a far smaller percentage of cases, there may be an excess of RBCs in the blood (erythrocytosis or polycythemia). This might obstruct the flow of blood through the tiny veins and arteries in extreme circumstances. 

Platelets 

Platelets, also known as thrombocytes, are small cell fragments that aid in the regular clotting of blood. A person with insufficient platelets is more likely to experience excessive bleeding and bruises. Excess platelets can induce excessive clotting or excessive bleeding if the platelets are not operating properly. The platelet count and size are determined by the CBC. 

Lab tests often ordered with a Complete Blood Count test: 

  • Reticulocytes
  • Iron and Total Iron Binding Capacity

Commonly Asked Questions: 

How does my health care provider use a Complete Blood Count test? 

The complete blood count (CBC) is a common, comprehensive screening test used to measure a person's overall health status.  

What do my Complete Blood Count results mean? 

A low Red Blood Cell Count, also known as anemia, could be due many different causes such as chronic bleeding, a bone marrow disorder, and nutritional deficiency just to name a few. A high Red Blood Cell Count, also known as polycythemia, could be due to several conditions including lung disease, dehydration, and smoking. Both Hemoglobin and Hematocrit tend to reflect Red Blood Cell Count results, so if your Red Blood Cell Count is low, your Hematocrit and Hemoglobin will likely also be low. Results should be discussed with your health care provider who can provide interpretation of your results and determine the appropriate next steps or lab tests to further investigate your health. 

What do my Differential results mean? 

A low White Blood Cell count or low WBC count, also known as leukopenia, could be due to a number of different disorders including autoimmune issues, severe infection, and lymphoma. A high White Blood Cell count, or high WBC count, also known as leukocytosis, can also be due to many different disorders including infection, leukemia, and inflammation. Abnormal levels in your White Blood Cell Count will be reflected in one or more of your different white blood cells. Knowing which white blood cell types are affected will help your healthcare provider narrow down the issue. Results should be discussed with your health care provider who can provide interpretation of your results and determine the appropriate next steps or lab tests to further investigate your health. 

What do my Platelet results mean? 

A low Platelet Count, also known as thrombocytopenia, could be due to a number of different disorders including autoimmune issues, viral infection, and leukemia. A high Platelet Count, also known as Thrombocytosis, can also be due to many different disorders including cancer, iron deficiency, and rheumatoid arthritis. Results should be discussed with your health care provider who can provide interpretation of your results and determine the appropriate next steps or lab tests to further investigate your health. 

NOTE: Only measurable biomarkers will be reported. Certain biomarkers do not appear in healthy individuals. 

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.

Description: A Comprehensive Metabolic Panel or CMP is a blood test that is a combination of a Basic Metabolic Panel, a Liver Panel, and electrolyte panel, and is used to screen for, diagnose, and monitor a variety of conditions and diseases such as liver disease, diabetes, and kidney disease. 

Also Known As: CMP, Chem, Chem-14, Chem-12, Chem-21, Chemistry Panel, Chem Panel, Chem Screen, Chemistry Screen, SMA 12, SMA 20, SMA 21, SMAC, Chem test

Collection Method: 

Blood Draw 

Specimen Type: 

Serum 

Test Preparation: 

9-12 hours fasting is preferred. 

When is a Comprehensive Metabolic Panel test ordered:  

A CMP is frequently requested as part of a lab test for a medical evaluation or yearly physical. A CMP test consists of many different tests that give healthcare providers a range of information about your health, including liver and kidney function, electrolyte balance, and blood sugar levels. To confirm or rule out a suspected diagnosis, abnormal test results are frequently followed up with other tests that provide a more in depth or targeted analysis of key areas that need investigating. 

What does a Comprehensive Metabolic Panel blood test check for? 

The complete metabolic panel (CMP) is a set of 20 tests that provides critical information to a healthcare professional about a person's current metabolic status, check for liver or kidney disease, electrolyte and acid/base balance, and blood glucose and blood protein levels. Abnormal results, particularly when they are combined, can suggest a problem that needs to be addressed. 

The following tests are included in the CMP: 

  • Albumin: this is a measure of Albumin levels in your blood. Albumin is a protein made by the liver that is responsible for many vital roles including transporting nutrients throughout the body and preventing fluid from leaking out of blood vessels. 

  • Albumin/Globulin Ratio: this is a ratio between your total Albumin and Globulin  

  • Alkaline Phosphatase: this is a measure of Alkaline phosphatase or ALP in your blood. Alkaline phosphatase is a protein found in all body tissues, however the ALP found in blood comes from the liver and bones. Elevated levels are often associated with liver damage, gallbladder disease, or bone disorder. 

  • Alt: this is a measure of Alanine transaminase or ALT in your blood. Alanine Aminotransferase is an enzyme found in the highest amounts in the liver with small amounts in the heart and muscles. Elevated levels are often associated with liver damage. 

  • AST: this is a measure of Aspartate Aminotransferase or AST. Aspartate Aminotransferase is an enzyme found mostly in the heart and liver, with smaller amounts in the kidney and muscles. Elevated levels are often associated with liver damage. 

  • Bilirubin, Total: this is a measure of bilirubin in your blood. Bilirubin is an orange-yellowish waste product produced from the breakdown of heme which is a component of hemoglobin found in red blood cells. The liver is responsible for removal of bilirubin from the body. 

  • Bun/Creatinine Ratio: this is a ratio between your Urea Nitrogen (BUN) result and Creatinine result.  

  • Calcium: this is a measurement of calcium in your blood. Calcium is the most abundant and one of the most important minerals in the body as it essential for proper nerve, muscle, and heart function. 

  • Calcium: is used for blood clot formation and the formation and maintenance of bones and teeth. 

  • Carbon Dioxide: this is a measure of carbon dioxide in your blood. Carbon dioxide is a negatively charged electrolyte that works with other electrolytes such as chloride, potassium, and sodium to regulate the body’s acid-base balance and fluid levels.  

  • Chloride: this is a measure of Chloride in your blood. Chloride is a negatively charged electrolyte that works with other electrolytes such as potassium and sodium to regulate the body’s acid-base balance and fluid levels. 

  • Creatinine: this is a measure of Creatinine levels in your blood. Creatinine is created from the breakdown of creatine in your muscles and is removed from your body by the kidneys. Elevated creatinine levels are often associated with kidney damage. 

  • Egfr African American: this is a measure of how well your kidneys are functioning. Glomeruli are tiny filters in your kidneys that filter out waste products from your blood for removal while retaining important substances such as nutrients and blood cells. 

  • Egfr Non-Afr. American: this is a measure of how well your kidneys are functioning. Glomeruli are tiny filters in your kidneys that filter out waste products from your blood for removal while retaining important substances such as nutrients and blood cells. 

  • Globulin: this is a measure of all blood proteins in your blood that are not albumin. 

  • Glucose: this is a measure of glucose in your blood. Glucose is created from the breakdown of carbohydrates during digestion and is the body’s primary source of energy. 

  • Potassium: this is a measure of Potassium in your blood. Potassium is an electrolyte that plays a vital role in cell metabolism, nerve and muscle function, and transport of nutrients into cells and removal of wastes products out of cells. 

  • Protein, Total: this is a measure of total protein levels in your blood. 
    Sodium: this is a measure of Sodium in your blood. Sodium is an electrolyte that plays a vital role in nerve and muscle function. 

  • Sodium: this is a measure of sodium in your blood's serum. Sodium is a vital mineral for nerve and muscle cell function.

  • Urea Nitrogen (Bun): this is a measure of Urea Nitrogen in your blood, also known as Blood UreaNitrogen (BUN). Urea is a waste product created in the liver when proteins are broken down into amino acids. Elevated levels are often associated with kidney damage. 

Lab tests often ordered with a Comprehensive Metabolic Panel test: 

  • Complete Blood Count with Differential and Platelets
  • Iron and Total Iron Binding Capacity
  • Lipid Panel
  • Vitamin B12 and Folate
  • Prothrombin with INR and Partial Thromboplastin Times

  • Liver Disease
  • Hypertension

Commonly Asked Questions: 

How does my health care provider use a Comprehensive Metabolic Panel test? 

The comprehensive metabolic panel (CMP) is a broad screening tool for assessing organ function and detecting diseases like diabetes, liver disease, and kidney disease. The CMP test may also be requested to monitor known disorders such as hypertension and to check for any renal or liver-related side effects in persons taking specific drugs. If a health practitioner wants to follow two or more separate CMP components, the full CMP might be ordered because it contains more information. 

What do my Comprehensive Metabolic Panel test results mean? 

The results of the tests included in the CMP are usually analyzed together to look for patterns. A single abnormal test result may indicate something different than a series of abnormal test findings. A high result on one of the liver enzyme tests, for example, is not the same as a high result on several liver enzyme tests. 

Several sets of CMPs, frequently performed on various days, may be examined to gain insights into the underlying disease and response to treatment, especially in hospitalized patients. 

Out-of-range findings for any of the CMP tests can be caused by a variety of illnesses, including kidney failure, breathing issues, and diabetes-related complications, to name a few. If any of the results are abnormal, one or more follow-up tests are usually ordered to help determine the reason and/or establish a diagnosis. 

Is there anything else I should know? 

A wide range of prescription and over-the-counter medications can have an impact on the results of the CMP's components. Any medications you're taking should be disclosed to your healthcare professional. Similarly, it is critical to provide a thorough history because many other circumstances can influence how your results are interpreted. 

What's the difference between the CMP and the BMP tests, and why would my doctor choose one over the other? 

The CMP consists of 14 tests, while the basic metabolic panel (BMP) is a subset of those with eight tests. The liver (ALP, ALT, AST, and bilirubin) and protein (albumin and total protein) tests are not included. If a healthcare provider wants a more thorough picture of a person's organ function or to check for specific illnesses like diabetes or liver or kidney disease, he or she may prescribe a CMP rather than a BMP. 

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.

Please note the following regarding BUN/Creatinine ratio: 

The lab does not report the calculation for the BUN/Creatinine Ratio unless one or both biomarkers’ results fall out of the published range. 

If you still wish to see the value, it's easy to calculate. Simply take your Urea Nitrogen (BUN) result and divide it by your Creatinine result.  

As an example, if your Urea Nitrogen result is 11 and your Creatinine result is 0.86, then you would divide 11 by 0.86 and get a BUN/Creatinine Ratio result of 12.79. 


Description: The cytomegalovirus antibodies test is used to detect antibodies to cytomegalovirus in the blood’s serum from a recent or past infection.

Also Known As: CMV Test, CMV Antibodies Test, CMV IgG IgM Test, Cytomegalovirus Test, Cytomegalovirus IgG IgM Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is a Cytomegalovirus Antibodies test ordered?

When a younger person, a pregnant woman, or an immune-compromised individual exhibits flu- or mono-like signs and symptoms, CMV tests, as well as tests for influenza, mononucleosis, and EBV, may be requested.

When a health care provider is assessing the effectiveness of antiviral therapy, one or more CMV tests might be requested at regular intervals.

CMV antibody testing may be requested as a screening test to discover if a person has been exposed to CMV in the past when they are a candidate for an organ or marrow transplant.

What does a Cytomegalovirus Antibodies blood test check for?

Cytomegalovirus is a widespread virus that is found all over the world but only rarely causes symptoms. CMV infection affects between 50 and 85 percent of individuals in the United States. The majority of persons get infected as children or young adults and have no noticeable symptoms or health problems.

CMV testing entails measuring CMV antibodies, immunological proteins produced in response to CMV infection, or detecting the virus itself. Culturing CMV or detecting the virus's genetic material in a fluid or tissue sample might be used to identify the virus during an active infection.

During an active infection, CMV can be discovered in a variety of body fluids, including saliva, urine, blood, breast milk, sperm, vaginal secretions, and cerebrospinal fluid. Close personal touch or interaction with infected materials, like as diapers or toys, makes it easy to spread to others. CMV, like other members of the herpes family, becomes dormant or latent after the initial "primary" infection has cured. Unless a person's immune system is considerably impaired, cytomegalovirus can live in them for the rest of their lives without creating any symptoms. The virus may reactivate if this occurs.

In three scenarios, CMV can cause serious health problems:

  • Primary CMV infection in young adults can induce a flu-like or mononucleosis-like disease. Extreme weariness, fever, chills, body pains, and/or headaches are common symptoms of this ailment, which normally goes away in a few weeks.
  • Primary CMV infection in babies can result in major physical and developmental issues. This happens when a pregnant woman becomes infected for the first time and then distributes the infection to her unborn child through the placenta. Most infected neonates appear healthy at birth, but within a few months, they may develop hearing or vision abnormalities, pneumonia, convulsions, and/or impaired mental development. Some babies are stillborn, while others show signs including jaundice, anemia, an enlarged spleen or liver, and a small head when they are born.
  • CMV can cause significant disease and death in people who have weaker immune systems. This includes those living with HIV/AIDS, people who have undergone organ or bone marrow transplants, and people who are receiving cancer chemotherapy. People with weakened immune systems who become infected for the first time may have the most severe symptoms, and their CMV infection may be active for a long time. Those who have previously been exposed to CMV may experience reactivation of their infection. Their eyes, digestive tract, lungs, and brain could all be affected. Spleen and liver problems are also possible, and people who have had organ or bone marrow transplants may have some rejection. Active CMV also weakens the immune system, making it easier for secondary infections like fungal infections to develop.

Lab tests often ordered with a Cytomegalovirus antibodies test:

  • Epstein Barr Virus Antibodies
  • Herpes 1 and 2
  • Varicella Zoster Virus

Conditions where a Cytomegalovirus antibodies test is recommended:

  • Epstein Barr Virus
  • HIV
  • Herpes
  • Chicken Pox and Shingles

How does my health care provider use a Cytomegalovirus antibodies test?

Cytomegalovirus testing is performed to see if someone has an active CMV infection based on their signs and symptoms. It's sometimes ordered to see if someone has ever been infected with CMV before.

CMV is a widespread virus that affects a large percentage of the population but rarely produces symptoms or serious health concerns. In neonates and persons with weaker immune systems, such as transplant recipients, cancer patients, people taking immunosuppressive medicines, and people living with HIV, primary CMV infection can cause serious sickness and consequences.

Antibody testing on blood samples can be used to detect if someone has been exposed recently or previously. IgM and IgG are the two types of CMV antibodies produced in response to a CMV infection, and one or both might be seen in the blood.

The first antibodies produced by the body in response to a CMV infection are IgM antibodies. Within a week or two of the initial exposure, they are present in the majority of people. Antibody production of IgM increases for a brief period before declining. CMV IgM antibody levels frequently decline below detectable levels after many months. When latent CMV is triggered, more IgM antibodies are generated.

The body produces IgG antibodies several weeks after the original CMV infection, which defend against secondary infections. IgG levels rise during active infection, then level off as the CMV infection fades and the virus becomes dormant. After being exposed to CMV, a person's blood will contain quantifiable amounts of CMV IgG antibodies for the rest of their lives. Along with IgM testing, CMV IgG antibody testing can be used to establish the existence of a current or previous CMV infection.

CMV antibody testing can be used to determine immunity to primary CMV infections in people who are awaiting organ or bone marrow transplantation, as well as in HIV/AIDS patients. CMV infection is common and causes minimal difficulties in those with healthy immune systems, hence general population screening is uncommon.

What do my CMV IgG and IgM test results mean?

When interpreting the findings of CMV testing, caution is advised. The results are compared to clinical data, such as signs and symptoms, by a health professional. It's not always easy to tell the difference between a latent, active, or reactivated CMV infection. This is attributable to a number of factors, including:

A healthy individual who has been infected with CMV will carry the virus for the rest of their lives. CMV can reactivate on a regular basis, frequently in a subclinical manner, shedding small amounts of virus into body fluids but causing no symptoms.

Even if the individual has an active case of CMV, an immune-compromised person may not have a significant antibody response to the infection; the person's IgM and IgG levels may be lower than predicted.

It's possible that the virus isn't present in large enough numbers in the fluid or tissue being analyzed to be detected.

A symptomatic person with positive CMV IgG and IgM has most likely been exposed to CMV for the first time or has had a previous CMV infection reactivated. IgG levels can be measured again 2 or 3 weeks later to confirm this. A high IgG level is less essential than an increasing level. If the IgG level in the first and second samples differs by fourfold, the person is infected with CMV.

A positive CMV IgM and negative IgG indicates that the person was infected recently.

In someone who is symptomatic, a negative IgG and/or IgM or low levels of antibodies may indicate that the person has a problem other than CMV or that their immune system is not responding correctly.

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.


CMV infections are common and usually asymptomatic. In patients who are immunocompromised, CMV may cause disseminated, severe disease. CMV may cause birth defects in a minority of infected newborns. Antibody IgG may represent prior exposure or recent infection if there is a significant change in titer between acute and convalescent specimens.

Description: The EBV antibody test is used to measure the antibodies present in the immune system. EBV tests are used to help diagnose mononucleosis (mono) by ruling out EBV and to differentiate between EBV infection and other infections that present with the same symptoms.

Also Known As: EBV Antibody Test, EBV Ab Test, EBV Test, EBV Panel, Epstein Barr Virus (EBV) Panel, Epstein Barr Virus EBV Antibody Panel

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is an Epstein-Barr Virus Antibody Panel test ordered?

When someone has symptoms that imply mono but a negative mono test, or when a pregnant woman has flu-like symptoms and her healthcare provider wants to know if the symptoms are caused by EBV or another microorganism, EBV antibody testing may be recommended.

When a healthcare provider wishes to know if they've been exposed to EBV before, testing might be ordered. When a healthcare provider wants to follow antibody concentrations or when the first test was negative but the healthcare practitioner still feels the person's symptoms are due to EBV, testing may be repeated.

What does an Epstein-Barr Virus Antibody Panel blood test check for?

The Epstein-Barr virus is a virus that causes a mild to moderate sickness in most people. Epstein-Barr virus blood tests detect EBV antibodies in the blood and aid in the diagnosis of EBV infection.

The Epstein-Barr virus produces a highly common infection. Most persons in the United States are infected with EBV at some point in their life, according to the Centers for Disease Control and Prevention. The virus is very contagious and can readily spread from one person to another. It is found in infected people's saliva and can be spread by intimate contact, such as kissing or sharing utensils or cups.

The incubation period is a period of several weeks following initial EBV exposure before related symptoms manifest. The virus multiplies in number during the acute primary infection. There is a drop in viral levels and a remission of symptoms after this, but the virus never totally disappears. EBV that stays latent in a person's body for the rest of their lives may reawaken, although it normally causes little problems unless the person's immune system is severely damaged.

The majority of people are infected with EBV as children and have few or no symptoms. When an infection arises in adolescence, however, it can lead to infectious mononucleosis, sometimes known as mono, which is characterized by fatigue, fever, sore throat, swollen lymph nodes, an enlarged spleen, and occasionally an enlarged liver. About 25% of infected teens and young adults experience these symptoms, which normally go away within a month or two.

Mono is usually diagnosed based on symptoms and the results of a full blood count and a mono test. About 25% of people with mono don't create heterophile antibodies, resulting in a negative mono test; this is especially true in youngsters. Antibodies to the EBV virus can be tested to see if the symptoms these people are having are due to a current infection with the virus.

The most prevalent cause of mono is EBV. Other causes of mono, according to the CDC, include CMV, hepatitis A, hepatitis B, or hepatitis C, rubella, and toxoplasmosis. It can be difficult to tell the difference between EBV and these other infections at times. For example, diagnosing the etiology of symptoms of a viral disease in a pregnant woman may be critical. Testing can assist distinguish between a primary EBV infection, which has not been demonstrated to harm a developing baby, and a CMV, herpes simplex virus, or toxoplasmosis infection, which can cause pregnancy difficulties and harm the fetus.

It's also crucial to rule out EBV infection and check for other possible explanations of symptoms. Those suffering from strep throat, a bacterial infection caused by group A streptococcus, must be recognized and treated with antibiotics. It's possible to have strep throat instead of mono, or to have both at the same time.

There are several assays for different types and classes of EBV antibodies. Antibodies are proteins produced by the body as part of an immune response to antigens from the Epstein-Barr virus. The amount of each of these EBV antibodies rises and declines as the illness proceeds during a primary EBV infection. Antibodies in the blood can help with diagnosis and can tell a doctor about the stage of illness and whether it's a current, recent, or past infection.

Antibody Viral Capsid Antigen-IgM antibody is commonly identified in the blood at this time. After being exposed to the virus, it appears for roughly 4 to 6 weeks before disappearing.

Antibody to VCA-IgG It appears during acute infection, with the maximum level at 2 to 4 weeks, then gradually decreases, stabilizes, and is present for the rest of one's life.

Antibody to the early antigen appears during the acute infection phase and subsequently fades; about 20% of people infected will have detectable amounts for several years after the EBV infection has cleared.

Lab tests often ordered with an Epstein-Barr Virus Antibody Panel test:

  • Mononucleosis
  • Complete Blood Count (CBC)
  • White Blood Cell Count (WBC)
  • Blood Smear
  • Cytomegalovirus
  • Toxoplasmosis

Conditions where an Epstein-Barr Virus Antibody Panel test is recommended:

  • Mononucleosis
  • Influenza
  • Pregnancy
  • Epstein-Barr Virus

How does my health care provider use an Epstein-Barr Virus Antibody Panel test?

If a person is symptomatic but has a negative mono test, blood tests for Epstein-Barr virus antibodies can help diagnose EBV infection, the most prevalent cause of infectious mononucleosis.

One or more EBV antibody tests, along with testing for cytomegalovirus, toxoplasmosis, and other infections, may be ordered in pregnant women with signs of a viral disease to assist distinguish between EBV and disorders that generate similar symptoms.

These tests may be conducted for asymptomatic people to see if they've been exposed to EBV before or are vulnerable to a primary EBV infection. This is not regularly done, but it may be requested if someone has been in intimate contact with a person who has mono, such as a teenager or an immunocompromised person.

The Centers for Disease Control and Prevention recommends ordering a variety of tests to assess whether a person is vulnerable to EBV, as well as to detect a recent or earlier infection, or a reactivated EBV infection.

What do my Epstein Barr Virus antibody test results mean?

When interpreting the findings of EBV antibody testing, caution is advised. The person being tested's indications and symptoms, as well as his or her medical history, must be considered. A healthcare provider may seek the advice of an infectious disease specialist, particularly one who is familiar with EBV testing.

If someone tests positive for VCA-IgM antibodies, they are most likely infected with EBV and may be in the early stages of the illness. Even though the mono test was negative, the individual is most likely to be diagnosed with mono if they also have symptoms linked with it.

If a person's VCA-IgG and EA-D IgG tests come back positive, it's quite likely that they have an active or recent EBV infection.

If VCA-IgM is negative but VCA-IgG and an EBNA antibody are positive, the person tested most likely had an EBV infection before.

If a person is asymptomatic and negative for VCA-IgG, he or she has most likely never been exposed to EBV and is hence susceptible to infection.

In general, growing VCA-IgG levels suggest a current EBV infection, whereas dropping values indicate a recently resolved EBV infection. However, EBV antibody concentrations must be interpreted with caution because the amount of antibody present is unrelated to the severity of the infection or the length of time it will remain. High amounts of VCA-IgG may be present, and they may stay that way for the rest of one's life.

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.

Also Known As: EBV VCA IgG AB Test, EBV Antibodies Test, EBV VCA Test, EBV IgG Ab Test, VCA IgG Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is an Epstein-Barr Virus Viral Capsid Antigen IgG Antibody test ordered?

When a person has symptoms that would indicate mono but a negative mono test, as well as when a pregnant woman has flu-like symptoms and her doctor wants to know whether the symptoms are caused by EBV or another microorganism, EBV antibody tests may be prescribed.

When a medical professional wants to confirm prior EBV exposure, testing may be required. Testing may occasionally be repeated if the medical professional wants to monitor antibody levels or if the results of the initial test were negative but the doctor still believes that the patient's symptoms are being caused by EBV.

What does an Epstein-Barr Virus Viral Capsid Antigen IgG Antibody blood test check for?

A mild to moderate disease is often brought on by the Epstein-Barr virus. Epstein-Barr virus blood tests aid in the diagnosis of EBV infection by detecting EBV antibodies in the blood.

Infections caused by the Epstein-Barr virus are highly prevalent. The majority of Americans have had EBV infection at some point in their life, according to the Centers for Disease Control and Prevention. The virus is quickly spread from person to person and is very contagious. It can be transmitted through close contact, such as kissing, sharing of utensils or cups, and saliva of sick people.

The incubation period after initial EBV exposure lasts for a number of weeks before any symptoms may manifest. The virus multiplies during the acute initial infection. The infection then starts to become less prevalent and the symptoms start to subside, but it never totally disappears. Latent EBV can reactivate and stays dormant in the body for the rest of a person's life, although it typically poses few risks unless the individual has seriously compromised immune function.

Most persons who receive EBV as children show little to no symptoms. But if the first infection happens in adolescence, it can lead to infectious mononucleosis, sometimes known as mono, which is characterized by fatigue, fever, sore throat, swollen lymph nodes, an enlarged spleen, and occasionally an enlarged liver. About 25% of adolescents and young adults with the infection experience these symptoms, which typically go away in a month or two.

Mono is normally identified by a person's symptoms, a full blood count, and the results of a mono test. A mono test will come back negative in about 25% of patients with mono; this is particularly true of youngsters. These patients do not produce heterophile antibodies. If these persons are currently infected with the EBV virus, it can be determined whether or not their symptoms are caused by that infection using tests for EBV antibodies.

The most typical cause of mono is EBV. The CDC lists CMV, hepatitis A, B, or C, rubella, and toxoplasmosis as examples of additional causes of mono. It can occasionally be crucial to separate EBV from these other diseases. For instance, determining the root of a pregnant woman's viral disease symptoms may be crucial. A primary EBV infection, which has not been proved to harm an unborn child, can be distinguished from CMV, herpes simplex virus, or toxoplasmosis infections through testing because these conditions can complicate pregnancy and provide a risk to the fetus.

Additionally, it may be crucial to rule out EBV infection and search for other potential reasons of the symptoms. Antibiotics must be administered to those who have group A streptococcus-related infections, such as those who have strep throat. It's possible for someone to have strep throat instead of mono, or even both illnesses simultaneously.

There are numerous tests available to check for various EBV antibody types and classes. The body produces antibodies, which are proteins, as an immunological reaction to several Epstein-Barr virus antigens. Each of these EBV antibodies has a fluctuating level during a primary EBV infection as the infection develops. The level of these antibodies in the blood can help with diagnosis and normally informs the medical professional of the infection's stage and whether it is a recent or prior infection.

Antibodies to VCA-IgG Emerges during acute infection, peaking at 2 to 4 weeks, before dipping slightly, stabilizing, and remaining for the rest of one's life.

Lab tests often ordered with an Epstein-Barr Virus Viral Capsid Antigen IgG Antibody test:

  • Epstein Barr Virus Early Antigen D Antibody IgG
  • Mononucleosis Test
  • Complete Blood Count (CBC)
  • Cytomegalovirus Test

Conditions where an Epstein-Barr Virus Viral Capsid Antigen IgG Antibody test is recommended:

  • Epstein Barr Virus
  • Mono
  • Influenza

How does my health care provider use an Epstein-Barr Virus Viral Capsid Antigen IgG Antibody test?

If a person has symptoms but a negative mono test, blood tests for Epstein-Barr virus antibodies can be done to assist detect EBV infection, the most prevalent cause of infectious mononucleosis.

One or more EBV antibody tests may be requested in addition to tests for cytomegalovirus, toxoplasmosis, and other infections in pregnant women who exhibit symptoms of a viral disease in order to help differentiate between EBV and other disorders that may present with similar symptoms.

An asymptomatic person may be given these tests to determine whether they have ever been exposed to EBV or are predisposed to developing a primary EBV infection. Although it is not usually done, it may be requested if a person—such as a teenager or someone with an impaired immune system—has recently been in close proximity to someone who has mono.

The Centers for Disease Control and Prevention advise running a number of tests to assist identify someone's susceptibility to EBV, as well as to look for recent, past, or reactivated EBV infections.

What do my Epstein-Barr Virus Viral Capsid Antigen IgG Antibody test results mean?

Results of EBV antibody testing must be interpreted carefully. It is necessary to take into account the test subject's indications and symptoms in addition to their medical background. A physician may seek the advice of an expert in infectious illnesses, particularly one with knowledge of EBV testing.

If someone tests positive for VCA-IgM antibodies, they most likely have an EBV infection and the sickness may still be in its early stages. Even if the mono test came back negative, the person will likely be diagnosed with mono if they also exhibit symptoms of the illness.

It is quite likely that someone has an active or recent EBV infection if both the VCA-IgG and the EA-D IgG tests are positive.

It is most likely that the person examined had an earlier EBV infection if the VCA-IgM test is negative but the VCA-IgG and an EBNA antibody are both positive.

A person who exhibits no symptoms and tests negative for VCA-IgG has probably never been exposed to EBV and is therefore susceptible to infection.

Rising VCA-IgG concentrations typically signify an ongoing EBV infection, whereas declining amounts typically signify a recent EBV infection that is healing. However, as the amount of antibody present does not correspond with the severity of the infection or how long it will remain, caution must be used when interpreting EBV antibody concentrations. There may be high levels of VCA-IgG and they could stay there for the rest of the person's life.

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.


Primary infection by EBV causes infectious mononucleosis, usually a self-limiting disease in children and young adults. Infection with EBV can cause lymphoproliferative disorders including tumors. VCA-IgM is typically detectable at clinical presentation, then declines to undetectable levels within a month in young children and within 3 months in other individuals.

Description: A Glucose test is a blood test used to screen for, diagnose, and monitor conditions that affect glucose levels such as prediabetes, diabetes, hyperglycemia, and hypoglycemia.

Also Known As: Fasting Blood Glucose Test, FBG Test, Fasting Blood Sugar Test, FBS Test, Fasting Glucose Test, FG Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: Fasting required

When is a Glucose test ordered?

Diabetes screening is recommended by several health groups, including the American Diabetes Association and the United States Preventive Services Task Force, when a person is 45 years old or has risk factors.

The ADA recommends retesting within three years if the screening test result is within normal limits, but the USPSTF recommends testing once a year. Annual testing may be used to monitor people with prediabetes.

When someone exhibits signs and symptoms of high blood glucose, a blood glucose test may be conducted.

Diabetics are frequently asked to self-check their glucose levels multiple times a day in order to monitor glucose levels and choose treatment alternatives as suggested by their doctor. Blood glucose levels may be ordered on a regular basis, along with other tests such as A1c, to track glucose control over time.

Unless they show early symptoms or have had gestational diabetes in a prior pregnancy, pregnant women are routinely screened for gestational diabetes between the 24th and 28th week of pregnancy. If a woman is at risk of type 2 diabetes, she may be tested early in her pregnancy, according to the American Diabetes Association. When a woman has type 1, type 2, or gestational diabetes, her health care provider will normally order glucose levels to monitor her condition throughout the duration of her pregnancy and after delivery.

What does a Glucose blood test check for?

A fasting glucose test measures glucose. Glucose is the major energy source for the body's cells and the brain and nervous system's only source of energy. A consistent supply must be provided, and a somewhat constant level of glucose in the blood must be maintained. The glucose level in the blood can be measured using a variety of methods. 

Fruits, vegetables, breads, and other carbohydrate-rich foods are broken down into glucose during digestion, which is absorbed by the small intestine and circulated throughout the body. Insulin, a hormone generated by the pancreas, is required for the use of glucose for energy production. Insulin promotes glucose transport into cells and instructs the liver to store surplus energy as glycogen for short-term storage or triglycerides in adipose cells.

Normally, blood glucose rises slightly after you eat or drink, and the pancreas responds by releasing insulin into the blood, the amount of which is proportional to the size and substance of the meal. The level of glucose in the blood declines as glucose enters the cells and is digested, and the pancreas responds by delaying, then ceasing the secretion of insulin.

When blood glucose levels fall too low, such as between meals or after a strong activity, glucagon is released, which causes the liver to convert some glycogen back into glucose, so boosting blood glucose levels. The level of glucose in the blood remains pretty steady if the glucose/insulin feedback loop is working appropriately. When the balance is upset and the blood glucose level rises, the body strives to restore it by boosting insulin production and removing excess glucose through the urine.

Several diseases can cause the equilibrium between glucose and pancreatic hormones to be disrupted, resulting in high or low blood glucose. Diabetes is the most common cause. Diabetes is a collection of illnesses characterized by inadequate insulin production and/or insulin resistance. Untreated diabetes impairs a person's ability to digest and utilize glucose normally. Type 1 diabetes is diagnosed when the body is unable to produce any or enough insulin. People with prediabetes or type 2 diabetes are insulin resistant and may or may not be able to produce enough of the hormone.

Organ failure, brain damage, coma, and, in extreme situations, death can result from severe, sudden fluctuations in blood glucose, either high or low. Chronically high blood glucose levels can harm body organs like the kidneys, eyes, heart, blood vessels, and nerves over time. Hypoglycemia can harm the brain and nerves over time.

Gestational diabetes, or hyperglycemia that exclusively arises during pregnancy, can affect some women. If left untreated, this can result in large babies with low glucose levels being born to these mothers. Women with gestational diabetes may or may not acquire diabetes later in life.

Lab tests often ordered with a Glucose test:

  • Complete Blood Count
  • Iron Total and Total Iron binding capacity
  • Hemoglobin A1c
  • Lipid Panel
  • Urinalysis Complete
  • TSH
  • CMP
  • Insulin
  • Microalbumin
  • Fructosamine
  • C-Peptide

Conditions where a Glucose test is recommended:

  • Diabetes
  • Kidney Disease
  • Insulin Resistance
  • Pancreatic Diseases
  • Hyperglycemia
  • Hypoglycemia

Commonly Asked Questions:

How does my health care provider use a Glucose test?

The blood glucose test can be used for a variety of purposes, including:

  • Detect hyperglycemia and hypoglycemia
  • Screen for diabetes in those who are at risk before symptoms appear; there may be no early indications or symptoms of diabetes in some circumstances. As a result, screening can aid in detecting it and allowing treatment to begin before the illness worsens or complications emerge.
  • Aid in the detection of diabetes, prediabetes, and gestational diabetes.
  • Monitor your blood sugar levels and manage your diabetes

Glucose levels should be monitored in those who have been diagnosed with diabetes.

Between the 24th and 28th week of pregnancy, glucose blood tests are performed to assess pregnant women for gestational diabetes. Pregnant women who have never been diagnosed with diabetes should be screened and diagnosed using either a one-step or two-step strategy, according to the American Diabetes Association and the US Preventive Services Task Force.

Other tests, including diabetic autoantibodies, insulin, and C-peptide, may be used in conjunction with glucose to assist in detecting the reason of elevated glucose levels, differentiate between type 1 and type 2 diabetes, and assess insulin production.

What does my glucose test result mean?

High blood glucose levels are most commonly associated with diabetes, but they can also be caused by a variety of other diseases and ailments.

Hypoglycemia is defined by a drop in blood glucose to a level that triggers nervous system symptoms before affecting the brain. The Whipple triad is a set of three criteria for diagnosing hypoglycemia.

Excessive exposure to heavy metals can cause acute chronic toxicity. Heavy metals panel is intended to evaluate and monitor exposure to heavy metals and evaluate the process of detoxification. Excessive cadmium exposure can damage lungs, kidneys, and the digestive tract.

Includes

Arsenic, Cadmium, Lead, Mercury, Creatinine

Patient Preparation

Avoid seafood consumption for 48 hours prior to collection


Excessive exposure to Heavy Metals can cause acute and chronic toxicity. Heavy Metals Panel is intended to evaluate and monitor exposure to heavy metals and evaluate the process of detoxification.

Description: A heavy metals test is a blood test that measures levels of toxic metals in your blood to check for metal poisoning.

Also Known As: Toxic Metals Test, Heavy Metals Blood Test

Collection Method: Blood Draw

Specimen Type: Whole Blood

Test Preparation: Avoid seafood consumption for 48 hours prior to sample collection

When is a Heavy Metals Panel test ordered?

If a medical professional believes that a patient has been acutely or chronically exposed to one or more heavy metals, a heavy metals panel may be prescribed. Depending on the type and amount of metal involved, the nature and severity of the signs and symptoms of heavy metal exposure will vary; early signs of poisoning can be missed because they are frequently non-specific. Even if a person has no, few, or vague symptoms, excessive exposure can nonetheless cause harm to numerous organs.

Those who might be exposed to metals at work are typically periodically observed. Safety precautions reduce danger to workers and aid in resolving issues when they arise. Several dangerous metals that can be present at work are regulated by the U.S. Occupational Safety and Health Administration. The affected individuals are monitored and action is made to lessen their exposure if excessive quantities are found.

What does a Heavy Metals Panel blood test check for?

A heavy metals panel is a collection of tests that assesses the levels of particular potentially harmful metals in blood, urine, or, less frequently, hair or other body fluids or tissues. A laboratory might offer tests for individual metals as well as various groupings of heavy metals panels. Lead, mercury, and arsenic are the most typical mixture. Other panels might contain one or more other metals, such copper, zinc, or cadmium. In addition to considering the patient's clinical symptoms, a healthcare professional will decide which metals to test for depending on possible exposure.

The definition of "heavy metals" is ambiguous. It refers to a number of elements with high density or metallic qualities and is connected to the periodic table of elements. These substances are naturally present throughout the environment, and businesses employ them to create a variety of everyday goods. Some of them, such as copper, iron, molybdenum, selenium, and zinc, are required in tiny amounts by the body for regular function but can be harmful at higher levels. Any of the heavy metals can irritate or harm the body in high doses, and they can contaminate the soil, air, food, and water as well as linger in the environment for a very long time. The terms "heavy metals" and "toxic metals" are commonly used interchangeably because they are a potential source of harm.

The signs and symptoms that an individual may suffer are influenced by the type of metal, its form, the quantity, the time of exposure, the type of exposure, the individual's age, and the general health of the individual. One form of a metal may be more dangerous than another, such as an organic vs an inorganic metal compound, and some metals are significantly more toxic than others. The amount of metal absorbed and the areas of the body that are impacted can vary depending on how a person is exposed. For instance, a metal may be far more poisonous and cause serious lung damage when its fumes are inhaled than it may be when it is held in the hand or is just moderately dangerous and poorly absorbed when consumed.

Moderate exposure over time should also be evaluated because severe acute exposure can harm you and, in some situations, be fatal. Small amounts of heavy metals can be processed by the body, but moderate to large levels can build up in the kidneys, liver, bones, and brain. Some metals can impair the body's capacity to create red and white blood cells and are thought to be carcinogenic, which increases the risk of developing cancer. Because exposure to low or moderate concentrations can disrupt physical and cognitive development and can irreparably damage the organs and brain, fetuses and young children are most at danger. A significant portion of the metals can be transferred from the mother to the fetus, and some can be transferred to the baby through breast milk.

Lab tests often ordered with a Heavy Metals Panel test:

  • Lead
  • Mercury
  • Iron
  • Copper

Conditions where a Heavy Metals Panel test is recommended:

  • Lead Poisoning
  • Iron Toxicity
  • Copper Toxicity
  • Mercury Poisoning

How does my health care provider use a Heavy Metals Panel test?

For people who may have been exposed to one or more heavy metals, heavy metal testing is used to check for or diagnose heavy metal toxicity. It is also used to monitor excessive metal concentrations in people who work with different heavy metals. Construction, mining, radiator repair shops, and shooting ranges are a few examples of these professions. Testing is also done to check how well chelation therapy, a method of getting rid of heavy metals from the body, is working.

A series of studies using heavy metal panels is put up to simulate possible metal exposures. One or more distinct categories for either blood or urine may be available in a laboratory. A medical professional will place an order for the metals panel based on the patient's profession, interests, potential exposure, and/or clinical symptoms.

A doctor may prescribe a specific test in place of or in addition to a panel if they have reason to believe that a patient has been exposed to a particular metal, such as lead. When testing for exposure, lead is frequently ordered on its own, especially in youngsters due to their heightened sensitivity to its effects. Some metals can also be measured in bodily tissues, fluid, hair, and nails. These are often purchased separately.

What do my Heavy Metals Panel test results mean?

The evaluation of heavy metals test results must be done with care. A low concentration of a heavy metal in the blood does not always imply that an excessive amount of exposure has not taken place. Heavy metals do not persist in the blood for a long time and do not linger in the urine. For instance, over time, lead is absorbed into the bones when it moves from the blood into the body's organs. Lead may be found in a person's blood, urine, organs, and bones if they were exposed to lead on a regular basis.

Due to their widespread presence in our environment, several heavy metals may be found in extremely low concentrations in the blood and urine of individuals who appear to be in good health. Age-related recommendations for safe levels of heavy metals can change over time as new knowledge regarding their safety becomes available.

Scientists discovered detectable mercury in nearly 8,000 participants in a research done in 2004 according to the Centers for Disease Control and Prevention, for instance. They came to the conclusion that mercury levels in the blood and urine tend to rise with age. Additionally, they claim that the presence of mercury in detectable amounts in the blood or urine does not necessarily indicate that mercury levels have a negative impact on health. Physicians and public health officials can use reference values from monitoring studies on mercury levels in the body to assess if a patient has been exposed to levels of mercury above those in the general population.

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.

Description: Hemoglobin A1c is the protein Hemoglobin found in red blood cells, but with glucose attached to it. Hemoglobin A1c is used to check for and monitor diabetes as it shows average blood glucose levels over the past 2 to 3 months.

Also Known As: A1c Test, HbA1c Test, Glycohemoglobin Test, Glycated Hemoglobin Test, Glycosylated Hemoglobin Test, HbA1c Test

Collection Method: Blood Draw

Specimen Type: Whole Blood

Test Preparation: No preparation required

When is a Hemoglobin A1c test ordered?

A1c may be requested as part of a routine physical examination or when a practitioner suspects a patient of having diabetes due to characteristic signs or symptoms of high blood sugar, such as:

  • Increased thirst and fluid intake
  • Increased urination
  • Increase in hunger
  • Fatigue
  • Vision is hazy
  • Infections that take a long time to heal

Adults who are overweight and have the following additional risk factors may consider doing the A1c test:

  • Physically inactive
  • Diabetes in a first-degree relative
  • Race/ethnicity that is at high risk such as African Americans, Latinos, Native Americans, Asian Americans, and Pacific Islanders
  • Blood pressure that is high
  • A lipid profile that is abnormal.
  • Polycystic ovarian syndrome 
  • Cardiovascular disease 
  • Insulin resistance and other conditions links to insulin resistance

People who have not been diagnosed with diabetes but have been assessed to be at an increased risk of developing diabetes should have their A1c levels tested at least once a year.

Monitoring

The A1c test may be performed 2 to 4 times a year, depending on the type of diabetes a person has, how well their diabetes is controlled, and the healthcare provider's recommendations. If diabetics are fulfilling treatment goals and have stable glycemic control, the American Diabetes Association advises A1c testing at least twice a year. A1c may be ordered quarterly when someone is first diagnosed with diabetes or if control isn't good.

What does a Hemoglobin A1c blood test check for?

Hemoglobin A1c, often known as A1c or glycated hemoglobin, is hemoglobin that has been attached to glucose. By assessing the proportion of glycated hemoglobin, the A1c test determines the average quantity of glucose in the blood during the previous 2 to 3 months.

Hemoglobin is a protein present inside red blood cells that transports oxygen.

Glycated hemoglobin is generated in proportion to the amount of glucose in the blood. Once glucose attaches to hemoglobin, it stays there for the duration of the red blood cell's life, which is usually about 120 days. The most common kind of glycated hemoglobin is known as A1c. A1c is created on a daily basis and is gradually removed from the bloodstream as older RBCs die and younger RBCs replace them.

This test can be used to detect and diagnose diabetes, as well as the risk of developing it. According to the American Diabetes Association's standards of medical care in diabetes, diabetes can be diagnosed using either A1c or glucose.

This test can also be used to track the progress of a diabetic patient's treatment. It aids in determining how well a person's glucose levels have been controlled over time by medication. An A1c of less than 7% suggests good glucose control and a lower risk of diabetic complications for the majority of diabetics for monitoring reasons.

Lab tests often ordered with a Hemoglobin A1c test:

  • Complete Blood Count
  • Glucose
  • Frucstosamine
  • Albumin
  • Comprehensive Metabolic Panel
  • Microalbumin w/creatinine
  • Lipid panel

Conditions where a Hemoglobin A1c test is recommended:

  • Type 1 Diabetes
  • Type 2 Diabetes

How does my health care provider use a Hemoglobin A1c test?

Adults can use the hemoglobin A1c test to screen for and diagnose diabetes and prediabetes.

A fasting glucose or oral glucose tolerance test should be done to screen or diagnose diabetes in these instances.

The A1c test is also used to track diabetics' glucose control over time. Diabetics strive to maintain blood glucose levels that are as close to normal as feasible. This helps to reduce the risks of consequences associated with chronically high blood sugar levels, such as progressive damage to body organs such as the kidneys, eyes, cardiovascular system, and nerves. The result of the A1c test depicts the average quantity of glucose in the blood over the previous 2-3 months. This can help diabetics and their healthcare professionals determine whether the steps they're taking to control their diabetes are working or if they need to be tweaked.

A1c is a blood test that is usually used to help newly diagnosed diabetics identify how high their uncontrolled blood glucose levels have been in the previous 2-3 months. The test may be ordered multiple times throughout the control period, and then at least twice a year after that to ensure that good control is maintained.

What does my Hemoglobin A1c test result mean?

HbA1c levels is currently reported as a percentage for monitoring glucose control, and it is suggested that most diabetics try to keep their hemoglobin A1c below 7%. The closer diabetics can keep their A1c to the therapeutic objective of less than 7% without experiencing abnormally low blood glucose, the better their diabetes is controlled. The risk of problems rises as the A1c rises.

However, a person with type 2 diabetes may have an A1c goal set by their healthcare professional. The length of time since diagnosis, the presence of other diseases as well as diabetes complications, the risk of hypoglycemia complications, life expectancy, and whether or not the person has a support system and healthcare resources readily available are all factors that may influence the goal.

For example, a person with heart disease who has had type 2 diabetes for many years without diabetic complications may have a higher A1c target set by their healthcare provider, whereas someone who is otherwise healthy and newly diagnosed may have a lower target set by their healthcare provider as long as low blood sugar is not a significant risk.

More than 20 million people in the United States struggle with neuropathy. These individuals experience pain and weakness that come from a defect in the nervous system.

Unfortunately, there's no cure for neuropathy. However, there are some available treatments that work better for patients who identify their condition early on.

Neuropathy lab tests are the best way to determine whether or not you have neuropathy or are currently developing it.

To learn more about neuropathy and the neuropathy tests that you need for a diagnosis, keep reading.

What Is Neuropathy?

Neuropathy is a condition of the nervous system that's associated with nerve damage. The condition can stand alone or develop as a result of another condition.

A couple of the common conditions that may cause neuropathy are diabetes and Guillain-Barre syndrome. Some patients may even develop neuropathy as a side effect of treatments like chemotherapy.

Neuropathy is also called peripheral neuropathy. Although peripheral neuropathy is localized to the legs and arms, neuropathy can occur anywhere in the body.

Neuropathy does not have a singular cause or symptom. It's a set of symptoms that occurs because of a few different processes happening in the body. 

Unfortunately, neuropathy is not curable. However, there are steps that you can take to prevent the condition before you develop it as well as steps that you can take to prevent the condition from worsening after you develop it.

Risk Factors for Neuropathy

The risk factors for neuropathy are linked to previous medical history and current lifestyle choices. Here are the common risk factors associated with neuropathy:

  • Diabetes
  • Cancer
  • HIV/AIDS
  • Vitamin B deficiency
  • Copper deficiency
  • Nutrient excess
  • Exposure to toxins

If you have any of these risk factors, it's important to let your health provider know so that they can better care for you. While having these conditions isn't guaranteed to lead to neuropathy, they are strongly correlated with them. 

Causes of Neuropathy

The most common cause of neuropathy is diabetes. Because of the changes in the blood that happen with the condition, it can lead to numbness and tingling in the legs and arms.

Cancer patients can experience chemotherapy-induced neuropathy. The chemo treatment kills fast-growing cells in the body. Unfortunately, it can go after some of your healthy cells as well.

Getting these treatments over time can cause damage to the nervous system as nerve cells die.

Autoimmune diseases can also cause neuropathy. People with these conditions have an immune system that is attacking healthy cells. Sometimes, this includes healthy nerve cells.

Infectious diseases can lead to neuropathy as well. Like with the HIV/AIDS virus, these infectious agents can cause damage to the nervous system over time.

Those people with HIV or AIDS can develop the condition from the virus, while others develop it from the medications that providers use to contain the virus.

Nutrition problems, including deficiencies, malnutrition, excess, and alcoholism can cause neuropathy as well. The imbalance within the body causes problems with the nerve cells, eventually leading to neuropathy.

Repetitive stress, inflammation, and irritation can also cause nerve problems. If you've had an injury in the past, you could be at risk of developing neuropathy.

Lastly, we should point out idiopathic neuropathy and genetic neuropathy. Idiopathic neuropathy has no known cause, while genetic neuropathy is passed down through families.

What Are the Signs and Symptoms of Neuropathy?

The signs and symptoms that a patient gets from neuropathy will depend on how advanced it is and what kind of neuropathy they have. Here are some of the most common signs and symptoms for patients with neuropathy:

  • Numbness
  • Tingling
  • Burning
  • Sensitivity to touch
  • Pain
  • Muscle weakness

Usually, these signs and symptoms occur in the arms and/or legs. However, the location of these signs and symptoms depends on the location of your neuropathy.

If the condition has a chance to develop too far, you could develop paralysis. It's important to catch the condition early.

How Is Neuropathy Diagnosed?

There are several ways that a healthcare provider can diagnose neuropathy. 

First, they could use electrodiagnostic testing. This includes a series of tests that look at the nerve function and nerve sensitivity in different areas of your body.

They can also use a needle examination, which requires using a needle to get audio and visual information about your muscle functioning.

Your healthcare provider may choose to get a skin biopsy. By look at the sample under a microscope, they can determine whether your neuropathy is associated with your nerve fibers.

Quantitive sensory testing is also an option. This can help healthcare providers determine how much damage there is to your existing nerves.

Lastly, your healthcare provider may want to run a couple of neuropathy blood tests to see if you have signs of inflammation and damage in your blood.

The Lab Tests to Screen, Diagnose, and Monitor Neuropathy

Since neuropathy is a nerve condition, there aren't many regular neuropathy lab tests. However, there are a few tests that can help your provider determine the kind of neuropathy that you have. These include the following:

By getting these kinds of tests, you can take the next steps when it comes to controlling your neuropathy. By knowing how it developed, you and your healthcare provider can make better decisions about your future health. This means that you may be able to slow down the development of the condition or even help with symptoms.
