Stroke and Lab Testing: What You Need to Know


Name Matches
Screening test for deficiencies of plasma coagulation factors other than Factors VII and XIII. The test is also used to monitor patients on heparin therapy.

Description: A Prothrombin Time test will measure the speed of which your blood clots. This test can be used to detect a bleeding or clotting disorder or to determine in your blood is clotting too fast or too slow.

Also Known As: Pro Time with INR Test, Prothrombin Time and International Normalized Ratio test, Prothrombin Time PT with INR Test, Prothrombin Time with INR Test, Prothrombin with INR, Protime with INR, PT Test

Collection Method: Blood draw

Specimen Type: Whole Blood

Test Preparation: No preparation required

When is a Prothrombin Time with INR test ordered?

When a person takes the anticoagulant medicine warfarin, a PT and INR are ordered on a regular basis to confirm that the prescription is working effectively and that the PT/INR is adequately extended. A doctor will prescribe them frequently enough to ensure that the treatment is having the desired effect, namely, boosting the person's clotting time to a therapeutic level while minimizing the danger of excessive bleeding or bruising.

When a person who isn't taking anticoagulants exhibits signs or symptoms of excessive bleeding or clotting, a PT may be ordered when they are experiencing:

  • Bleeding that isn't explained or bruises that isn't easy to get rid of
  • Nosebleeds
  • Gums that are bleeding
  • A blood clot in an artery or vein
  • Disseminated intravascular coagulation
  • A persistent disorder that affects hemostasis, such as severe liver disease

PT and PTT may be prescribed prior to surgery when there is a high risk of blood loss associated with the procedure and/or when the patient has a clinical history of bleeding, such as frequent or severe nosebleeds and easy bruising, which may indicate the presence of a bleeding problem.

What does a Prothrombin Time with INR blood test check for?

The prothrombin time is a test that determines a person's capacity to make blood clots properly. The international normalized ratio, or INR, is a calculation based on the results of a PT that is used to track people who are taking the blood thinner warfarin.

After chemicals are added to a person's blood sample, a PT measures how long it takes for a clot to develop. The PT is frequently used with a partial thromboplastin time to measure the number and function of proteins known as coagulation factors, which are essential for optimal blood clot formation.

When an injury develops in the body and bleeding ensues, the clotting process known as hemostasis begins. This process is aided by a series of chemical events known as the coagulation cascade, in which coagulation or "clotting" components are activated one by one, leading to the development of a clot. In order for normal clotting to occur, each coagulation factor must be present in appropriate quantities and operate effectively. Excessive bleeding can result from too little, while excessive clotting can result from too much.

There are two "pathways" that can trigger clotting in a test tube during a laboratory test, the extrinsic and intrinsic pathways. Both of these pathways subsequently converge to finish the clotting process. The PT test assesses how well all coagulation factors in the extrinsic and common routes of the coagulation cascade cooperate. Factors I, II, V, VII, and X are included. The PTT test examines the protein factors XII, XI, IX, VIII, X, V, II, and I, as well as prekallikrein and high molecular weight kininogen, which are all part of the intrinsic and common pathways. The PT and PTT examine the overall ability to generate a clot in a fair period of time, and the test results will be delayed if any of these elements are insufficient in quantity or are not operating effectively.

The PT test is normally done in seconds and the results are compared to a normal range that represents PT levels in healthy people. Because the reagents used to conduct the PT test vary from one laboratory to the next and even within the same laboratory over time, the normal ranges will change. The Internationalized Normalized Ratio, which is computed based on the PT test result, was developed and recommended for use by a World Health Organization committee to standardize results across various laboratories in the United States and around the globe for people taking the anticoagulant warfarin.

The INR is a formula that accounts for variations in PT reagents and enables for comparison of findings from different laboratories. When a PT test is performed, most laboratories report both PT and INR readings. However, the INR should only be used by people who are taking the blood thinner warfarin.

Lab tests often ordered with a Prothrombin Time with INR test:

  • Partial Thromboplastin Time
  • Fibrinogen Activity
  • Platelet Count
  • Complete Blood Count (CBC)
  • Coagulation Factors
  • Warfarin Sensitivity testing

Conditions where a Prothrombin Time with INR test is recommended:

  • Bleeding Disorders
  • Excessive Clotting Disorders
  • Vitamin K Deficiency
  • Liver Disease
  • DIC

How does my health care provider use a Prothrombin Time with INR test?

The prothrombin time is used to diagnose the origin of unexplained bleeding or abnormal blood clots, generally in conjunction with a partial thromboplastin time. The international normalized ratio is a calculation based on the results of a PT that is used to monitor people on the blood thinner warfarin.

Coagulation factors are proteins that are involved in the body's process of forming blood clots to assist stop bleeding. When an injury occurs and bleeding begins, coagulation factors are triggered in a series of events that finally assist in the formation of a clot. In order for normal clotting to occur, each coagulation factor must be present in appropriate quantities and operate effectively. Excessive bleeding can result from too little, while excessive clotting can result from too much.

The PT and INR are used to monitor the anticoagulant warfarin's efficacy. This medication influences the coagulation cascade's function and aids in the prevention of blood clots. It is given to those who have a history of recurrent abnormal blood clotting on a long-term basis. Warfarin therapy's purpose is to strike a balance between preventing blood clots and causing excessive bleeding. This equilibrium must be carefully monitored. The INR can be used to change a person's medication dosage in order to get their PT into the ideal range for them and their condition.

What do my PT and INR test results mean?

Most laboratories report PT findings that have been corrected to the INR for persons taking warfarin. For basic "blood-thinning" needs, these persons should have an INR of 2.0 to 3.0. Some people with a high risk of blood clot require a higher INR, about 2.5 to 3.5.

The outcome of a PT test is determined by the method utilized, with results measured in seconds and compared to a normal range defined and maintained by the laboratory that administers the test. This normal range is based on the average value of healthy persons in the area, and it will differ somewhat from test to lab. Someone who isn't on warfarin would compare their PT test result to the usual range provided by the laboratory that conducted the test.

A prolonged PT indicates that the blood is taking an excessive amount of time to clot. This can be caused by liver illness, vitamin K inadequacy, or a coagulation factor shortage, among other things. The PT result is frequently combined with the PTT result to determine what condition is present.

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


PT-Screening test for deficiencies of plasma coagulation factors other than Factors VII and XIII. The test is also used to monitor patients on heparin therapy. PTT-Screening test for abnormalities of coagulation factors that are involved in the extrinsic pathway. Also used to monitor effects of Warfarin therapy and to study patients with hereditary and acquired clotting disorders.

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.

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.

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.

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. 

  • 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
  • Sed Rate (ESR)
  • C-Reactive Protein

Conditions where a Comprehensive Metabolic Panel test is recommended: 

  • Diabetes
  • Kidney Disease
  • 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: A Lipid Panel is a blood test that measures your cholesterol levels to evaluate your risk of cardiovascular disease.

Also Known As: Lipid Profile Test, Lipid Test, Cholesterol Profile Test, Cholesterol Panel Test, Cholesterol Test, Coronary Risk Panel Test, lipid blood test, Lipid w/Ratios Test, Cholesterol Ratio test, blood cholesterol Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: Patient should be fasting 9-12 hours prior to collection.

When is a Lipid Panel with Ratios test ordered?

A fasting lipid profile should be done about every five years in healthy persons who have no additional risk factors for heart disease. A single total cholesterol test, rather than a complete lipid profile, may be used for initial screening. If the screening cholesterol test result is high, a lipid profile will almost certainly be performed.

More regular testing with a full lipid profile is indicated if other risk factors are present or if earlier testing revealed a high cholesterol level.

Other risk factors, in addition to high LDL cholesterol, include:

  • Smoking
  • Obesity or being overweight
  • Unhealthy eating habits
  • Not getting enough exercise and being physically inactive
  • Older age
  • Having hypertension
  • Premature heart disease in the family
  • Having experienced a heart attack or having pre-existing heart disease

Diabetes or pre-diabetes is a condition in which a person has High HDL is a "negative risk factor," and its existence permits one risk factor to be removed from the total.

The American Academy of Pediatrics recommends routine lipid testing for children and young adults. Children and teenagers who are at a higher risk of developing heart disease as adults should be screened with a lipid profile earlier and more frequently. A family history of heart disease or health problems such as diabetes, high blood pressure, or being overweight are some of the risk factors, which are comparable to those in adults. According to the American Academy of Pediatrics, high-risk children should be examined with a fasting lipid profile between the ages of 2 and 8.

A lipid profile can also be done at regular intervals to assess the effectiveness of cholesterol-lowering lifestyle changes like diet and exercise, as well as pharmacological therapy like statins.

What does a Lipid Panel with Ratios blood test check for?

Lipids are a class of fats and fat-like compounds that are essential components of cells and energy sources. The level of certain lipids in the blood is measured by a lipid profile.

Lipoprotein particles transport two key lipids, cholesterol and triglycerides, through the bloodstream. Protein, cholesterol, triglyceride, and phospholipid molecules are all present in each particle. High-density lipoproteins, low-density lipoproteins, and very low-density lipoproteins are the three types of particles assessed with a lipid profile.

It's critical to keep track of and maintain optimal levels of these lipids in order to stay healthy. While the body creates the cholesterol required for normal function, some cholesterol is obtained from the diet. A high amount of cholesterol in the blood can be caused by eating too many foods high in saturated fats and trans fats or having a hereditary tendency. The excess cholesterol may form plaques on the inside walls of blood vessels. Plaques can constrict or block blood channel openings, causing artery hardening and raising the risk of a variety of health problems, including heart disease and stroke. Although the explanation for this is unknown, a high level of triglycerides in the blood is linked to an increased risk of developing cardiovascular disease.

A lipid profile consists of the following elements:

  • Cholesterol total
  • HDL Cholesterol - commonly referred to as "good cholesterol" since it eliminates excess cholesterol from the body and transports it to the liver for elimination.
  • LDL Cholesterol - commonly referred to as "bad cholesterol" because it deposits excess cholesterol in the walls of blood arteries, contributing to atherosclerosis.
  • Triglycerides
  • Ratio of LDL to HDL cholesterol

Lab tests often ordered with a Lipid Panel with Ratios test:

  • CBC (Blood Count Test) with Smear Review
  • Comprehensive Metabolic Panel
  • Direct LDL
  • VLDL
  • Lp-PLA2
  • Apolipoprotein A1
  • Apolipoprotein B
  • Lipoprotein (a)
  • Lipoprotein Fractionation Ion Mobility (LDL Particle Testing)

Conditions where a Lipid Panel with Ratios test is recommended:

  • Hypertension
  • Cardiovascular Disease
  • Heart Disease
  • Stroke

Commonly Asked Questions:

How does my health care provider use a Lipid Panel with Ratios test?

The lipid profile is used as part of a cardiac risk assessment to help determine an individual's risk of heart disease and, if there is a borderline or high risk, to help make treatment options.

Lipids are a class of fats and fat-like compounds that are essential components of cells and energy sources. It's critical to keep track of and maintain optimal levels of these lipids in order to stay healthy.

To design a therapy and follow-up strategy, the results of the lipid profile are combined with other recognized risk factors for heart disease. Treatment options may include lifestyle changes such as diet and exercise, as well as lipid-lowering drugs such as statins, depending on the results and other risk factors.

A normal lipid profile test measures the following elements:

  • Total cholesterol is a test that determines how much cholesterol is present in all lipoprotein particles.
  • HDL Cholesterol — measures hdl cholesterol in particles, sometimes referred to as "good cholesterol" since it eliminates excess cholesterol and transports it to the liver for elimination.
  • LDL Cholesterol – estimates the cholesterol in LDL particles; sometimes known as "bad cholesterol" since it deposits excess cholesterol in blood vessel walls, contributing to atherosclerosis. The amount of LDL Cholesterol is usually estimated using the total cholesterol, HDL Cholesterol, and triglycerides readings.
  • Triglycerides – triglycerides are measured in all lipoprotein particles, with the highest concentration in very-low-density lipoproteins.
  • As part of the lipid profile, several extra information may be presented. The results of the above-mentioned tests are used to determine these parameters.
  • VLDL Cholesterol — derived using triglycerides/5; this calculation is based on the typical VLDL particle composition.
  • Non-HDL Cholesterol - the result of subtracting total cholesterol from HDL Cholesterol.
  • Cholesterol/HDL ratio — total cholesterol to HDL Cholesterol ratio computed.

An expanded profile may include the amount and concentration of low-density lipoprotein particles. Rather than assessing the amount of LDL cholesterol, this test counts the number of LDL particles. This figure is thought to more accurately reflect the risk of heart disease in some persons.

What do my Lipid Panel test results mean?

Healthy lipid levels, in general, aid in the maintenance of a healthy heart and reduce the risk of heart attack or stroke. A health practitioner would analyze the results of each component of a lipid profile, as well as other risk factors, to assess a person's total risk of coronary heart disease, if therapy is required, and, if so, which treatment will best serve to reduce the person's risk of heart disease.

The Adult Treatment Panel III of the National Cholesterol Education Program published guidelines for measuring lipid levels and selecting treatment in 2002. The American College of Cardiology and the American Heart Association announced updated cholesterol therapy guidelines in 2013 to minimize the risk of cardiovascular disease in adults. These guidelines suggest a different treatment method than the NCEP guidelines. Cholesterol-lowering medications are now chosen based on the 10-year risk of atherosclerotic cardiovascular disease and other criteria, rather than on LDL-C or non-HDL-C objectives.

The revised guidelines include an evidence-based risk calculator for ASCVD that may be used to identify people who are most likely to benefit from treatment. It's for adults between the ages of 40 and 79 who don't have a heart condition. The computation takes into account a number of characteristics, including age, gender, race, total cholesterol, HDL-C, blood pressure, diabetes, and smoking habits. The new guidelines also suggest comparing therapeutic response to LDL-C baseline readings, with decrease criteria varying depending on the degree of lipid-lowering medication therapy.

Unhealthy lipid levels, as well as the presence of additional risk factors like age, family history, cigarette smoking, diabetes, and high blood pressure, may indicate that the person being examined needs to be treated.

The NCEP Adult Treatment Panel III guidelines specify target LDL cholesterol levels based on the findings of lipid testing and these other main risk factors. Individuals with LDL-C levels over the target limits will be treated, according to the guidelines.

According to the American Academy of Pediatrics, screening youths with risk factors for heart disease with a full, fasting lipid panel is advised. Fasting is not required prior to lipid screening in children who do not have any risk factors. For non-fasting lipid screening, non-high-density lipoprotein cholesterol is the preferred test. Non-HDL-C is computed by subtracting total cholesterol and HDL-C from total cholesterol and HDL-C.

Is there anything else I should know?

The measurement of triglycerides in people who haven't fasted is gaining popularity. Because most of the day, blood lipid levels reflect post-meal levels rather than fasting levels, a non-fasting sample may be more representative of the "usual" circulating level of triglyceride. However, because it is still unclear how to interpret non-fasting levels for assessing risk, the current recommendations for fasting before lipid tests remain unchanged.

A fasting lipid profile is usually included in a routine cardiac risk assessment. In addition, research into the utility of additional non-traditional cardiac risk markers, such as Lp-PLA2, is ongoing. A health care provider may use one or more of these markers to help determine a person's risk, but there is no consensus on how to use them and they are not widely available.

Cardiolipin Antibodies (IgA, IgG, IgM)

  • Cardiolipin Antibody (IgA) 
  • Cardiolipin Antibody (IgG) 
  • Cardiolipin Antibody (IgM) 

Cardiolipin antibodies (CA) are seen in a subgroup of patients with autoimmune disorders, particularly systemic lupus erythematosus (SLE), who are at risk for vascular thrombosis, thrombocytopenia, cerebral infarct and/or recurrent spontaneous abortion. Elevations of CA associated with increased risk have also been seen in idiopathic thrombocytopenic purpura, rheumatoid and psoriatic arthritis, and primary Sjögren's syndrome.


Description: An antinuclear antibody screening is a blood test that is going to look for a positive or negative result. If the result comes back as positive further test will be done to look for ANA Titer and Pattern. Antinuclear antibodies are associated with Lupus.

Also Known As: ANA Test, ANA Screen IFA with Reflex to Titer and pattern IFA Test, ANA with Reflex Test, Antinuclear Antibody Screen Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

IMPORTANT Reflex Information: If ANA Screen, IFA is positive, then ANA Titer and Pattern will be performed at an additional charge of $13.00

When is an ANA Screen test ordered?

When someone exhibits signs and symptoms of a systemic autoimmune illness, the ANA test is requested. Symptoms of autoimmune illnesses can be vague and non-specific, and they can fluctuate over time, steadily deteriorate, or oscillate between periods of flare-ups and remissions.

What does an ANA Screen blood test check for?

Antinuclear antibodies are a type of antibody produced by the immune system when it is unable to differentiate between its own cells and foreign cells. Autoantibodies are antibodies that attack the body's own healthy cells, causing symptoms like tissue and organ inflammation, joint and muscle discomfort, and weariness. The moniker "antinuclear" comes from the fact that ANA specifically targets chemicals located in a cell's nucleus. The presence of these autoantibodies in the blood is detected by the ANA test.

The presence of ANA may be a sign of an autoimmune process, and it has been linked to a variety of autoimmune illnesses, the most common of which being systemic lupus erythematosus.

One of the most common tests used to detect an autoimmune disorder or rule out other conditions with comparable signs and symptoms is the ANA test. As a result, it's frequently followed by other autoantibody tests that can help establish a diagnosis. An ENA panel, anti-dsDNA, anti-centromere, and/or anti-histone test are examples of these.

Lab tests often ordered with an ANA Screen test:

  • ENA Panel
  • Sed Rate (ESR)
  • C-Reactive Protein
  • Complement
  • AMA
  • Centromere antibody
  • Histone Antibody

Conditions where an ANA Screen test is recommended:

  • Autoimmune Disorders
  • Lupus
  • Rheumatoid Arthritis
  • Sjogren Syndrome
  • Scleroderma

How does my health care provider use an ANA Screen test?

One of the most often performed tests to diagnose systemic lupus erythematosus is the antinuclear antibody test. It serves as the first step in the evaluation process for autoimmune diseases that might impact various body tissues and organs.

When a person's immune system fails to discriminate between their own cells and foreign cells, autoantibodies called ANA are created. They attack chemicals found in a cell's nucleus, causing organ and tissue damage.

ANA testing may be utilized in conjunction with or after other autoantibody tests, depending on a person's indications and symptoms and the suspected condition. Antibodies that target specific compounds within cell nuclei, such as anti-dsDNA, anti-centromere, anti-nucleolar, anti-histone, and anti-RNA antibodies, are detected by some of these tests, which are considered subsets of the general ANA test. In addition, an ENA panel can be utilized as a follow-up to an ANA.

These further tests are performed in addition to a person's clinical history to assist diagnose or rule out other autoimmune conditions such Sjögren syndrome, polymyositis, and scleroderma.

To detect ANA, various laboratories may employ different test procedures. Immunoassay and indirect fluorescent antibody are two typical approaches. The IFA is regarded as the gold standard. Some labs will test for ANA using immunoassay and then employ IFA to confirm positive or equivocal results.

An indirect fluorescent antibody is created by mixing a person's blood sample with cells attached to a slide. Autoantibodies in the blood bind to the cells and cause them to react. A fluorescent antibody reagent is used to treat the slide, which is then inspected under a microscope. The existence of fluorescence is observed, as well as the pattern of fluorescence.

Immunoassays—these procedures are frequently carried out using automated equipment, however they are less sensitive than IFA in identifying ANA.

Other laboratory tests linked to inflammation, such as the erythrocyte sedimentation rate and/or C-reactive protein, can be used to assess a person's risk of SLE or another autoimmune disease.

What do my ANA test results mean?

A positive ANA test indicates the presence of autoantibodies. This shows the presence of an autoimmune disease in someone who has signs and symptoms, but more testing is needed to make a definitive diagnosis.

Because ANA test results can be positive in persons who have no known autoimmune disease, they must be carefully assessed in conjunction with a person's indications and symptoms.

Because an ANA test can become positive before signs and symptoms of an autoimmune disease appear, determining the meaning of a positive ANA in a person who has no symptoms can take some time.

SLE is unlikely to be diagnosed with a negative ANA result. It is normally not required to repeat a negative ANA test right away; however, because autoimmune illnesses are episodic, it may be desirable to repeat the ANA test at a later date if symptoms persist.

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


Troponin I is part of a protein complex which regulates the contraction of striated muscle. In acute coronary syndromes (ACS), it can be detected in blood at 4-8 hours following the onset of chest pain, reaches a peak concentration at 12-16 hours, and remains elevated for 5-9 days. Troponin I has been used as a reliable marker in the diagnosis of perioperative myocardial infarction in patients undergoing cardiac surgery.


Description: Creatine Kinase is a test that is measuring for the level of CK in the blood’s serum. CK is found in the heart tissue and the skeletal muscle. This test can be used to determine if there has been damage done to the muscles.

Also Known As: CK Test, Total Ck Test, Creatine Phosphokinase, CPK Test, CPK Level

Collection Method: Blood draw

Specimen Type: Serum

Test Preparation: No preparation required

When is a Creatine Kinase Total test ordered?

When muscle injury is suspected, a CK test may be requested, as well as at regular intervals to monitor for continuing damage. When a muscle illness, such as muscular dystrophy, is suspected, or when someone has suffered physical trauma, such as crushing injuries or major burns, it may be ordered. The test may be ordered if a person is experiencing symptoms of muscular damage, such as:

  • Muscle aches and pains
  • Muscle deterioration
  • Urine that is dark in color

When a person has nonspecific symptoms, testing may be recommended, especially if they are using a drug or have been exposed to a substance that has been associated to potential muscle damage.

What does a Creatine Kinase Total blood test check for?

The enzyme creatine kinase is found in the brain, heart, skeletal muscle, and other organs. When there is muscle injury, more CK is released into the bloodstream. The quantity of creatine kinase in the blood is measured in this test.

Skeletal muscles produce the little quantity of CK that is routinely found in the blood. An increase in CK can be caused by any disorder that causes muscular injury and/or interferes with muscle energy generation or usage. Strenuous activity and muscle inflammation, known as myositis, as well as muscle illnesses such muscular dystrophy, can raise CK levels. Rhabdomyolysis, or the severe breakdown of skeletal muscle tissue, is linked to a large increase in CK levels.

Lab tests often ordered with a Creatine Kinase Total test:

  • CK-MB
  • Myoglobin
  • Troponin
  • Lipid Panel
  • Hs-CRP
  • Homocysteine
  • Lipoprotein Fractionation, Ion Mobility

Conditions where a Creatine Kinase Total test is recommended:

  • Endocrine System and Syndromes
  • Lupus
  • Rheumatoid Arthritis
  • Heart Attack

How does my health care provider use a Creatine Kinase Total test?

A creatine kinase test can be used to detect muscle inflammation or damage caused by muscle illnesses such muscular dystrophy, or to help diagnose rhabdomyolysis if signs and symptoms are present. Other blood chemistry tests, such as electrolytes, BUN, or creatinine, may be conducted in addition to CK. A urine myoglobin test may be requested as well.

Muscle injury can present with few or vague symptoms such as weakness, fever, and nausea, which can also be associated with a range of other illnesses. In these circumstances, a healthcare practitioner may utilize a CK test to detect muscle injury, particularly if the person is taking a statin, using ethanol or cocaine, or has been exposed to a known toxin linked to probable muscle damage. A CK test may be used to assess and monitor muscle damage in those who have been physically injured.

Muscle injury can be tracked using a series of CK tests to evaluate if it improves or worsens. If a CK is increased and the site of muscle damage is unknown, a healthcare provider may order CK isoenzymes or a CK-MB as follow-up tests to differentiate between the three forms of CK: CK-MB, CK-MM, and CK-BB.

The CK test was originally one of the most common tests used to diagnose a heart attack, but the troponin test has mostly superseded it in the United States. The CK test, on the other hand, may be used to detect a second heart attack that occurs soon after the first.

What do my Creatine Kinase test results mean?

A high CK level, or a spike in levels in subsequent samples, often suggests that muscle injury has occurred recently, although it does not identify the location or origin of the damage. Serial test findings that peak and then begin to decline indicate that new muscle damage has subsided, whereas increasing and persistent elevations indicate that new muscle damage has persisted.

Increased CK levels can be detected in a range of muscular disorders caused by a variety of factors. Depending on the severity of muscle damage, people's CK levels may be significantly to severely elevated. Rhabdomyolysis patients may have CK levels that are 100 times higher than usual, and in some cases even higher.

Normal CK levels could mean there hasn't been any muscle injury or that it happened a few days before the test.

Following severe exercise, such as weight lifting, contact sports, or long exercise sessions, moderately elevated CK levels may be observed.

Aids in diagnosis of decreased activity of Protein C characterized by recurrent venous thrombosis. Acquired deficiencies associated with Protein C include: oral anticoagulant therapy, liver disease, vitamin K deficiency, malignancy, consumptive DIC, surgery, trauma, antibodies to Protein C and hepatic immaturity of the newborn.


The Protein S Functional (also known as Protein S, Activity) test assesses protein activity to determine its ability to regulate blood clotting and screen for an excessive clotting disease. 

This Protein S Functional test measures protein S activity to evaluate if they regulate blood clotting appropriately and to screen for a potential blood clotting issue.

This Protein S Functional test can be ordered to assess protein S activity to see whether blood clotting is being adequately regulated and to check for potential blood clotting disorders. Blood clot formation is controlled by the interaction of proteins S and C. Hemostasis, also referred to as bleeding, takes place when a blood vessel is damaged. In order to restrict blood loss until the blood artery has healed, platelets, which are blood cells, team up with proteins S and C (coagulation factors) to create a clot at the wound. For a stable clot to form, there must be enough platelet count, and coagulation factors and each must be in good working order. 

A deficiency or malfunction of these proteins may result in excessive blood clotting or a condition known as deep vein thrombosis (DVT). Deep vein thrombosis may begin in the arms or legs and move to the lungs, causing a potentially fatal pulmonary embolism (PE). 

An underlying health problem such as: 

  • Pregnancy 
  • Hepatic disease 
  • Renal disease 
  • Virulent diseases (HIV/AIDS). 
  • Cancer 
  • Use of Warfarin (Coumadin®) 
  • In certain cases, it may be a genetic disorder. 

Protein S exists in two states, free and bound, but only the free form binds to protein C. Consequently, protein S deficits can be classified into three groups: 

  • Deficiency owing to insufficient quantity 
  • Deficiency owing to improper function 
  • Deficiency due to lower quantities of free protein S, but normal levels of total protein S 

Individuals who have suffered excessive blood clots in unexpected areas or blood clots for unexplained reasons should consider ordering this test. This test can also assist in determining if the lower protein S activity is the result of a deficiency or a rare malfunction.

What does elevated Protein S activity indicate? 
In most cases, elevated Protein S levels are clinically insignificant and not connected with medical issues. Activity and concentrations of protein C and Protein S antigens indicate normal clotting control. A low level of Protein S activity might result in abnormal or excessive blood coagulation. 

What causes low Protein S activity?
Acquired Protein S deficiency is caused by a condition such as liver illness, nephrotic syndrome, some infections, oral contraceptives, vitamin K deficiency, surgery, or chemotherapy. 

What is the severity of Protein S deficiency? 
Individuals with modest Protein S deficiency are susceptible to developing deep vein thrombosis (DVT) in the deep veins of the arms or legs. A pulmonary embolism, a potentially fatal blood clot, can result from a DVT that enters the bloodstream and lodges in the lungs (PE) 

What is the functional test for protein S? 
Protein S aids in blood coagulation regulation. A deficiency of this Protein or an issue with its function may lead to the formation of blood clots in veins. This test is also used to screen the relatives of individuals with known Protein S deficiency. This test is sometimes used to determine the cause of repeated miscarriages. 

What should your levels of Protein S be? 
Typically, these percentage values should range between 60 and 150. There may be minor variations between testing centers. Low amounts of protein S may raise the risk of blood clots, although high levels do normally not cause for worry. 

Can a lack of Protein S induce a stroke? 
In young populations, Protein S deficiency is an uncommon cause of recurrent ischemic stroke. 

How can Protein S insufficiency be treated? 
If you have Protein S deficiency but have never had a blood clot, you will likely not need therapy unless certain conditions apply. Heparin, warfarin, rivaroxaban, apixaban, and dabigatran are anticoagulants that are commonly prescribed. 

How does a protein deficiency manifest itself? 
Protein insufficiency manifests as fatigue, weakness, hair loss, brittle nails, and dry skin. Protein deficit is particularly prevalent among vegans, vegetarians, individuals over the age of 70, and those with digestive disorders such as celiac disease and Crohn's disease. 

Aspirin and protein S deficiency: can it help? 
Many specialists recommend that women with Protein S deficiency, a history of fetal death, and severe or recurrent eclampsia get prophylactic-dose low molecular weight heparin (LMWH) medication during pregnancy, with the LMWH prophylaxis continuing for 6 weeks postpartum.


Preferred test in patients with Lupus anticoagulant, on heparin or direct thrombin inhibitors, or on Factor VIII concentrates.

Description: Sed Rate is a blood test that is used to measure the rate that red blood cells fall to the bottom of a test tube. The measurement is based how many cells fall within one hour. This test can be used to determine infection or inflammation.

Also Known As: Erythrocyte Sedimentation Rate Test, ESR Test, Sed Rate Test, Sedimentation Rate Test, Westergren Sedimentation Rate Test

Collection Method: Blood Draw

Specimen Type: Whole Blood

Test Preparation: No preparation required

When is a Sed Rate test ordered?

When a condition or disease is believed to be causing inflammation in the body, an ESR may be ordered. Several inflammatory illnesses can be identified using this test. It may be requested, for example, if arthritis is suspected of producing joint inflammation and pain, or if inflammatory bowel disease is suspected of causing digestive symptoms.

When a person develops symptoms of polymyalgia rheumatica, systemic vasculitis, or temporal arteritis, such as headaches, neck or shoulder discomfort, anemia, pelvic pain, poor appetite, joint stiffness, and unexplained weight loss, a doctor may recommend an ESR. To follow the development of specific illnesses, the sed rate test can also be routinely ordered.

A health practitioner may wish to repeat the ESR before undertaking a full workup to look for disease.

What does a Sed Rate blood test check for?

The erythrocyte sedimentation rate is a test that evaluates the degree of inflammation in the body indirectly. The test evaluates the rate at which erythrocytes fall in a blood sample that has been placed in a tall, thin, vertical tube. The millimeters of clear fluid present at the upper portion of the tube after one hour are reported as the results.

When a drop of blood is inserted in a tube, the red blood cells settle out slowly, leaving just a small amount of transparent plasma. In the presence of an increased number of proteins, particularly proteins known as acute phase reactants, red cells settle at a faster pace. Inflammation raises the levels of acute phase reactants such as C-reactive protein and fibrinogen in the blood.

An inherent component of the immune system's response is inflammation. It could be chronic, showing symptoms over time with conditions like autoimmune illnesses or cancer, or acute, showing symptoms right away after a shock, injury, or infection.

The ESR is a non-specific indication that can rise in a number of disorders; it is not a diagnostic test. It provides you with a fundamental understanding of whether you have an inflammatory condition or not.

Given the availability of more recent, specialized tests, there have been reservations about the ESR's utility. The ESR test, on the other hand, is commonly used to diagnose and monitor temporal arteritis, systemic vasculitis, and polymyalgia rheumatica. Extremely high ESR values can aid in differentiating between rheumatic diseases. Furthermore, ESR may still be a viable alternative in some cases, such as when newer tests are unavailable in resource-constrained places or while monitoring the progression of a disease.

Lab tests often ordered with a Sed Rate test:

  • C-Reactive Protein
  • ANA
  • Rheumatoid Factor

Conditions where a Sed Rate test is recommended:

  • Vasculitis
  • Autoimmune Disorders
  • Rheumatoid Arthritis
  • Osteoarthritis
  • Celiac Disease
  • Lupus
  • Chronic Fatigue Syndrome
  • Juvenile Rheumatoid Arthritis
  • Inflammatory Bowel Disease

How does my health care provider use a Sed Rate test?

The erythrocyte sedimentation rate is a non-specific, very straightforward test that has been used for many years to detect inflammation associated with infections, malignancies, and autoimmune illnesses.

Because an elevated ESR often indicates the presence of inflammation, but does not tell the health practitioner where the inflammation is in the body or what is causing it, it is referred to as a non-specific test. Other illnesses besides inflammation may have an impact on an ESR. As a result, other tests, such C-reactive protein, are routinely paired with the ESR.

ESR is used to identify temporal arteritis, systemic vasculitis, and polymyalgia rheumatica, among other inflammatory illnesses. A notably elevated ESR is one of the crucial test results used to support the diagnosis.

This test can be used to track disease activity and treatment response in both of the disorders mentioned above, as well as several others including systemic lupus erythematosus.

What do my Sed Rate test results mean?

Because ESR is a non-specific inflammatory measure that is influenced by a variety of circumstances, it must be used in conjunction with other clinical findings, the individual's medical history, and the results of other laboratory tests. The health practitioner may be able to confirm or rule out a suspected illness if the ESR and clinical data match.

Without any signs of a specific condition, a single elevated ESR is usually insufficient to make a medical conclusion. A normal result does not, however, rule out inflammation or illness.

Inflammation, as well as anemia, infection, pregnancy, and aging, can cause a moderately raised ESR.

A severe infection with a rise in globulins, polymyalgia rheumatica, or temporal arteritis are common causes of an extremely high ESR. Depending on the person's symptoms, a health practitioner may employ various follow-up tests, such as blood cultures. Even if there is no inflammation, people with multiple myeloma or Waldenstrom's macroglobulinemia have extraordinarily high ESRs.

Rising ESRs may suggest increased inflammation or a poor response to therapy when monitoring a condition over time; normal or falling ESRs may indicate an adequate response to treatment.

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


Syphilis (RPR + FTA-ABS)

  • FTA-ABS - Treponema pallidum Ab (Confirmation for Syphilis RPR test).
  • Syphilis RPR ( RPR (Monitor) with Reflex to Titer)

FTA-ABS - Treponema pallidum Ab

Clinical Significance

The FTA-ABS is a specific treponemal assay to detect antibody to t. Pallidum. The FTA-ABS becomes reactive 4-6 weeks after infection. Unlike the nontreponemal tests, once the FTA-ABS test becomes reactive, it will remain reactive for many years. Since the reactivity found with the FTA-ABS does not indicate response to therapy, it is not suitable for monitoring treatment. The FTA-ABS test does not distinguish between syphillis and other treponematoses such as yaws, pinta and bejil.

The treponemal antibody test (FTA-ABS) is often used as an initial test. A positive result indicates the presence of syphilis antibodies in the blood, but since treponemal antibodies remain positive even after an infection has been treated, it does not indicate whether the person has a current infection or was infected in the past. Conversely, nontreponemal antibodies as detected with an RPR typically disappear in an adequately treated person after about 3 years. Thus, if an initial treponemal test is positive, an RPR can be performed to differentiate between an active or past infection. In this case, a positive RPR would confirm that the person has been exposed to syphilis and, if not treated previously, has an active infection or, if treatment had occurred more than 3 years ago, possible re-infection.

Alternative Name(s) 

Treponemal pallidum, Fluorescent Treponemal Antigen, Syphilis

 

Syphilis RPR ( RPR (Monitor) with Reflex to Titer)

Reference Range(s)

Non-Reactive

Clinical Significance

This is a non-treponemal screening test for syphilis. False positive results may occur due to systemic lupus erythematosus, leprosy, brucellosis, atypical pneumonia, typhus, yaws, pinta, or pregnancy. Monitoring of RPR is helpful in assessing effectiveness of therapy.

IMPORTANT

A positive RPR screen and a positive result on the FTA-ABS confirms the screening result and the affected person is diagnosed with syphilis.

A negative result on the treponemal test may mean that the initial RPR test was falsely positive. Further testing and investigation may be done to determine the cause of the false positive.

Limitations

False-positive results have been associated in patients with infections, pregnancy, autoimmune disease, old age, Gaucher disease, and malignancy.

To screen for APC-R associated with venous thromboembolic disorders.

The Antiphospholipid Antibody Panel is a comprehensive test that measures nine biomarkers associated with antiphospholipid syndrome (APS). APS is an autoimmune disorder that can lead to recurrent miscarriages, thrombosis, and pregnancy complications. The panel includes tests for beta-2-glycoprotein I antibodies, phosphatidylserine antibodies, and cardiolipin antibodies.

This comprehensive testing will provide your healthcare provider with important information about your risk for APS and allow them to tailor your treatment accordingly. If you have been diagnosed with APS, it is important to see your healthcare provider regularly and follow their treatment recommendations. Sometimes, treatment with blood thinners or other medications may be necessary to prevent serious complications. Most people with APS can lead healthy, normal lives with proper management.

What is included in the antiphospholipid panel?

The panel includes tests for

  • Beta-2-Glycoprotein I Antibodies (IgG, IgA, IgM)
  • Phosphatidylserine Antibodies (IgG, IgA, IgM)
  • Cardiolipin Antibodies (IgA, IgG, IgM)

What is the antiphospholipid antibody panel test for?

The Antiphospholipid Antibody Panel is a comprehensive test that measures nine biomarkers associated with antiphospholipid syndrome (APS). APS is an autoimmune disorder that can lead to recurrent miscarriages, thrombosis, and pregnancy complications. The panel includes tests for beta-2-glycoprotein I antibodies, phosphatidylserine antibodies, and cardiolipin antibodies. This comprehensive testing will provide your healthcare provider with important information about your risk for APS and allow them to tailor your treatment accordingly.

What do the results of an antiphospholipid antibody panel test mean?

A positive result on any of the panel tests suggests that you have antibodies associated with APS in your blood. This does not necessarily indicate that you have APS, but it raises your chances of having the disorder. Your healthcare professional will analyze your results and, if necessary, conduct more tests.

What follow-up is necessary after an antiphospholipid antibody panel test?

If you have a positive result on any of the tests in the panel, your healthcare provider will likely order additional testing to confirm the diagnosis of APS. Once APS has been diagnosed, it is important to see your healthcare provider regularly and follow their treatment recommendations. Treatment with blood thinners or other drugs may be required in some cases to avoid serious consequences. With careful management, most persons with APS can live healthy, regular lives.

Is APS the same as lupus?

No, APS is an autoimmune condition that can cause thrombosis, repeated miscarriages, and pregnancy difficulties. Chronic inflammatory disease called lupus can harm several organs. Although they are both autoimmune illnesses, the two conditions are not the same.

Is APS an autoimmune disease?

Yes, APS is an autoimmune condition. When the body's immune system targets healthy cells and tissues, autoimmune disorders result. In APS, the immune system assaults the ubiquitous phospholipids present in all cells. This can result in repeated miscarriages, thrombosis, and problems during pregnancy.

What are the symptoms of APS?

The most common symptom of APS is recurrent miscarriages. Other symptoms may include thrombosis, pregnancy complications, and stroke. Many people with APS do not have any symptoms.

What are the causes of APS?

The exact causes of APS remain unknown. However, it is believed to be a result of both genetic and environmental influences.

What are the risks of APS?

APS can lead to recurrent miscarriages, thrombosis, and pregnancy complications. If left untreated, APS can also lead to stroke or heart attack.

How is APS diagnosed?

APS is typically diagnosed with a blood test. The Antiphospholipid Antibody Panel is a comprehensive test that measures nine different biomarkers that are associated with APS. Your healthcare practitioner will assist you in interpreting your results and, if required, order more tests.

How is APS treated?

There is no cure for APS. However, it is treatable with medicine and lifestyle modifications. Medications may include blood thinners or other medications to prevent serious complications. Lifestyle changes may include avoiding smoking, maintaining a healthy weight, and managing stress. With proper management, most people with APS can lead healthy, normal lives.

What is the prognosis for APS?

The prognosis for APS is generally good. Most people with APS can lead healthy, normal lives with proper diagnosis and treatment. However, APS can lead to serious complications if it is not properly managed. Recurrent miscarriages, thrombosis, and pregnancy complications are the most common complications associated with APS. If left untreated, APS can also lead to stroke or heart attack.

What are the three antiphospholipid antibodies?

The three antiphospholipid antibodies are beta-2-glycoprotein I, phosphatidylserine, and cardiolipin. These antibodies are associated with APS and can lead to recurrent miscarriages, thrombosis, and pregnancy complications.


This test will aid physicians in the assessment of risk of atrial fibrilation and cardioembolic stroke.

Cardio IQ Lp-PLA2 Activity

Clinical Significance

Lipoprotein-associated phospholipase A2 (Lp-PLA2), also known as platelet activating factor Acetylhydrolase, is an inflammatory enzyme that circulates bound mainly to low density lipoproteins and has been found to be localized and enriched in atherosclerotic plaques. In multiple clinical trials, Lp-PLA2 activity has been shown to be an independent predictor of coronary heart disease and stroke in the general population. Measurement of Lp-PLA2 may be used along with traditional cardiovascular risk factor measures for identifying individuals at higher risk of cardiovascular disease events. Clinical management may include beginning or intensifying risk reduction strategies. The activity assay is an enzyme assay run on an automated chemistry platform.


HDL cholesterol is inversely related to the risk for cardiovascular disease. It increases following regular exercise, moderate alcohol consumption and with oral estrogen therapy. Decreased levels are associated with obesity, stress, cigarette smoking and diabetes mellitus.

Most Popular

Total serum cholesterol analysis is useful in the diagnosis of hyperlipoproteinemia, atherosclerosis, hepatic and thyroid diseases.


Clinical Significance

Bacterial sepsis constitutes one of the most serious infectious diseases. The detection of microorganisms in a patient's blood has importance in the diagnosis and prognosis of endocarditis, septicemia, or chronic bacteremia.

Includes

Aerobic culture, anaerobic culture. If culture is positive, identification will be performed at an additional charge (CPT code(s): 87076 or 87106 or 87077 or 87140 or 87143 or 87147 or 87149).
Antibiotic susceptibilities are only performed when appropriate (CPT code(s): 87181 or 87184 or 87185 or 87186).


Factor V (Leiden) Mutation is a point mutation that causes resistance of Factor V protein degradation by activated protein C (APC). This mutation is associated with increased risk of venous thrombosis.


Stroke is a condition caused by the sudden blockage or diminished blood supply to a part of the brain.  This changes/affects body functions controlled by the part of the brain, hence reduced response or no response to stimulation at all. Stroke mainly happens when/if these brain cells do not get oxygen and nutrients made available by the fresh supply of blood. Body cells, and brain cells may get inflamed or even die if they do not get enough oxygen and nutrients, one of the reasons why stroke leaves one permanently disabled.  

Statistics show that more than 129,000 Americans die from stroke each year, with approximately 795,000 people suffering new or recurrent stroke annually. This makes stroke the 5th leading cause of death in the United States. 65% of all stroke-related deaths occur in women. In addition to causing long-term disability in most survivors, at least 25% of them are at risk of suffering another stroke within five years. 

Types of Stroke  

  • Ischemic: This is the most common type of stroke, accounting for more than 87% of reported cases. It is mainly caused by a blocked artery to the brain (thrombotic stroke). This can occur as a result of a blood clot in a narrow artery, or if the clot (in other parts of the body) breaks off and travels to the brain, commonly known as an embolic stroke. 
  • Hemorrhagic stroke: This type of stroke occurs when/if a blood vessel ruptures, causing breeding in and around the brain. This could be as a result of a head injury (from an accident) or aneurysms. Aneurysms occur as a result of high blood pressure or a genetic defect.  This is the most dangerous type of stroke, which almost always leads to death.  

Risk Factors 

The most common risk factors include: 

  • Diabetes mellitus  
  • High blood pressure  
  • Dangerously high cholesterol levels  
  • Age (seniors have a risk)  
  • Hereditary genetics  
  • Race (African Americans have a higher risk of stroke when compared to Caucasians)  
  • Sex (more men suffer a stroke as compared to women, while more women succumb to it quickly)  
  • Sickle cell anemia   
  • Antiphospholipid antibody syndrome  
  • Leading an unhealthy lifestyle (lack of exercise, drug abuse, and unhealthy eating habits)   

Signs and Symptoms

Most people will have one or more mini strokes, commonly known as TIAs (Transient Ischemic Attacks), before having an actual one. These mini strokes should serve as a warning and a reason to seek medical attention as soon as possible. Symptoms of stroke can be persistent, with TIAs fading off within no time. The most common symptoms of TIA or Stroke include:  

  • Severe, unexplained headache  
  • Trouble talking, sudden loss of speech, and difficulties understanding what is being said  
  • Sudden loss of coordination, balance, and trouble walking  
  • Paralysis of the leg, arm, or face (on one side of the body), sudden weakness and numbness 
  • Unexpected difficulties in seeing with one or both eyes and blurred vision.   

Tests  

Doctors mainly use non-laboratory testing for stroke diagnosis. These include several imaging tests, a neurological and physical exam. Researchers are, however, in the process of finding laboratory tests that could be used in stroke diagnosis, screening, treatment, and management. Stroke biomarkers may also come in handy in the future.  

Some of the feasible biomarkers that could be used in risk assessment include N-methyl-D-aspartate neuroreceptors (NMDAR), Lp-PLA2, and NT-PRoBNP. Antibodies to metalloproteinases (MMPs) and NR2A/2B are potential candidates for stroke diagnosis as well. A panel of biomarkers could be used in both risk assessment and diagnostic tools for stroke. All these are, however, in the research stage, hence, yet to be tested.  

Some lab tests may also be ordered to assess a patient’s risk. These include:  

More tests may be required to identify situations that could increase your risk. These include:
