Description: A Magnesium test is a blood test that measures magnesium levels in your blood’s serum and is useful in determining the cause of abnormal levels of magnesium, calcium, and or potassium, and is useful in the evaluation of a wide variety of disorders such as diabetes, kidney disease, and malabsorption.

Also Known As: Magnesium RBC Test, Magnesium Red Bood Cell Test, Mg Test, Mag test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is a Magnesium RBC test ordered?

Magnesium tests may be requested by health professionals as a follow-up to chronically low calcium and potassium levels in the blood. It may also be prescribed if a person exhibits symptoms of a magnesium deficiency, such as twitching, muscle weakness, cramping, disorientation, seizures, or cardiac arrhythmias.

As part of an evaluation of malabsorption, malnutrition, diarrhea, or alcoholism, a health practitioner may prescribe a magnesium level to check for a deficit. Testing may also be done if someone is taking drugs that cause the kidneys to excrete magnesium. When magnesium and/or calcium supplementation is required, the level of magnesium in the blood can be measured at regular intervals to ensure that the medication is working.

A magnesium test, along with kidney function tests such as a BUN and creatinine, may be given on a regular basis when someone has a kidney problem or uncontrolled diabetes to help monitor renal function and ensure that the person is not excreting or retaining excessive quantities of magnesium.

What does a Magnesium RBC test check for?

The magnesium test measures the amount of magnesium in your blood’s serum. Magnesium is a mineral that supports healthy bones, muscle contraction, neuron function, and energy production. It enters the body through the diet and is then absorbed by the small intestine and colon. Bones, cells, and tissues all contain the element magnesium. It is challenging to determine the total magnesium content from blood tests alone since only 1% of the magnesium present in the body is accessible in the blood. However, this test is still useful for figuring out a person's magnesium levels.

Small levels of magnesium can be found in a range of meals, including green vegetables like spinach, whole grains, and nuts. Magnesium is commonly found in foods that contain dietary fiber. The body regulates how much magnesium it receives and excretes or conserves in the kidneys to keep its magnesium level stable.

Magnesium deficiency can occur as a result of malnutrition, malabsorption-related disorders, or excessive magnesium loss via the kidneys. Magnesium overload can occur as a result of taking magnesium-containing antacids or a decrease in the kidneys' ability to eliminate magnesium.

There may be no or few nonspecific symptoms in someone with mild to severe magnesium insufficiency. Nausea, loss of appetite, exhaustion, confusion, muscle cramps, seizures, changes in heart rate, and numbness or tingling are all symptoms of persistent or severe deficits. They can also wreak havoc on calcium metabolism and worsen calcium deficiency. Nausea, muscle weakness, loss of appetite, and an erratic heart rate are some of the symptoms of excess magnesium, which are similar to those of deficiency.

Lab tests often ordered with a Magnesium RBC test:

  • Complete Blood Count
  • Calcium
  • Iron Total and Total Iron binding capacity
  • Potassium
  • Comprehensive Metabolic Panel
  • Lipid Panel
  • Phosphorus
  • Parathyroid Hormone
  • Vitamin D
  • Glucose

Conditions where a Magnesium RBC test is recommended:

  • Kidney Disease
  • Hypothyroidism
  • Diabetes
  • Alcoholism
  • Malnutrition
  • Malabsorption
  • Diarrhea
  • Dehydration
  • Parathyroid Diseases
  • Addison Disease
  • Adrenal Insufficiency

How does my health care provider use a Magnesium RBC test?

Magnesium levels in the blood are measured with a magnesium test. Atypical magnesium levels are most frequently found in conditions or illnesses that result in insufficient or excessive renal excretion of magnesium or impaired intestinal absorption of magnesium. Magnesium levels can be measured to determine the severity of kidney issues, uncontrolled diabetes, and/or uncontrolled diabetes as well as to diagnose gastrointestinal diseases.

Because a low magnesium blood level can lead to chronically low calcium and potassium levels over time, it may be tested to help diagnose calcium, phosphorus, potassium, and/or parathyroid hormone – another component of calcium regulation – problems.

Magnesium levels can be checked on a regular basis to monitor the response to oral or intravenous magnesium supplements, and calcium supplementation can be monitored using calcium and phosphorus tests.

What does my Magnesium RBC test result mean?

Low magnesium levels in the blood can suggest that a person isn't getting enough magnesium or is excreting too much. Deficiencies are most commonly encountered in:

  • Low nutritional intake 
  • Gastrointestinal conditions
  • Diabetes that is uncontrolled
  • Hypoparathyroidism
  • Use of a diuretic for a long time
  • diarrhea that lasts for a long time
  • Following surgery
  • Burns that are severe
  • Pregnancy toxicity

Magnesium levels in the blood are rarely elevated as a result of food sources, but rather as a result of an excretion problem or excessive supplementation. Increased levels can be cause by:

  • Failure of the kidneys
  • Hyperparathyroidism
  • Hypothyroidism
  • Dehydration
  • Diabetic acidosis
  • Addison's disese
  • Use of antacids or laxatives containing magnesium

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

Description: A Basic Metabolic Panel is a blood test used to screen for, diagnose, and monitor a variety of conditions and diseases such as diabetes and kidney disease.  

Also Known As: BMP, Chemistry Panel, Chemistry Screen, Chem 7, Chem 11, BMP Test, SMA 7, SMAC7, Basic Metabolic Test, Chem Test, Chem Panel Test 

Collection Method: Blood Draw 

Specimen Type: Serum 

Test Preparation: 9-12 hours fasting is preferred. 

When is a Basic Metabolic Panel test ordered?  

A BMP may be requested as part of a standard physical examination. 

The panel is frequently ordered in hospital emergency rooms because its components provide vital information regarding a person's renal state, electrolyte and acid/base balance, blood glucose, and calcium levels. Significant changes in these test results can suggest serious issues such as renal failure, insulin shock or diabetic coma, respiratory distress, or abnormalities in heart rhythm. 

What does a Basic Metabolic Panel blood test check for? 

The basic metabolic panel (BMP) is a 9-test panel that provides essential information to a health practitioner about a person's current metabolic status, including kidney health, blood glucose level, electrolyte and acid/base balance. Abnormal results, particularly when they are combined, can suggest a problem that needs to be addressed. 

The following tests are included in the BMP test: 

  • 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 also 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. 

  • 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. 

  • 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 Urea Nitrogen (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 Basic Metabolic Panel test: 

  • Complete Blood Count with Differential and Platelets
  • Hemoglobin A1c
  • Iron and Total Iron Binding Capacity
  • Lipid Panel
  • Insulin
  • Vitamin B12 and Folate
  • C-Reactive Protein

Conditions where a Basic Metabolic Panel test is recommended: 

  • Diabetes 
  • Kidney Disease 
  • Liver Disease 

Commonly Asked Questions: 

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

The basic metabolic panel (BMP) is used to evaluate a person's kidney function, electrolyte, acid/base balance, and blood glucose level, all of which are linked to their metabolism. It can also be used to keep track of hospitalized patients and persons with known illnesses like hypertension and hypokalemia. 

If a health practitioner wants to track two or more separate BMP components, the full BMP might be ordered because it contains more information. Alternatively, when monitoring, the healthcare provider may order specific tests, such as a follow-up glucose, potassium, or calcium test, or an electrolyte panel to track sodium, potassium, chloride, and CO2. If a doctor needs further information, he or she can request a comprehensive metabolic panel (CMP), which is a collection of 21 tests that includes the BMP. 

What do my Basic Metabolic Panel results mean? 

The results of the tests included in the BMP are usually analyzed together to look for patterns. A single abnormal test result may indicate something different than a series of abnormal test findings. 

Out-of-range results on any of the BMP's tests can be caused by a number of things, including kidney failure, breathing issues, and diabetes-related consequences. 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? 

The results of the BMP components can be influenced by a range of prescription and over-the-counter medicines. Any medications you're taking should be disclosed to your healthcare professional. Similarly, it is critical to provide them with a thorough medical history because many other circumstances can influence how your results are interpreted. 

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.

Serum calcium is involved in the regulation of neuromuscular and enzyme activity, bone metabolism and blood coagulation. Calcium blood levels are controlled by a complex interaction of parathyroid hormone, vitamin D, calcitonin and adrenal cortical steroids. Calcium measurements are useful in the diagnosis of parathyroid disease, some bone disorders and chronic renal disease. A low level of calcium may result in tetany.

The ionized calcium is determined by an ion selective electrode methodology. The result that is generated is pH adjusted. The result is empirically based on a measured pH and ionized calcium concentration normalized to a pH of 7.40. This calculation compensates for in vitro changes in pH due to loss of CO2 through specimen handling. Ionized calcium represents the true "bioavailable" calcium in the circulation. In situations where the total calcium is normal but does not fit the clinical picture, e.g., hyperparathyroidism, a determination of the ionized calcium will, many times, show an elevation in the "bioavailable" calcium component. This may be due to alterations in protein concentrations, especially albumin, that binds most of the calcium in the circulation.

Description: Ceruloplasmin is a blood test that measures that amount of Ceruloplasmin in the blood’s serum. Ceruloplasmin, or Copper Oxide, is a protein that is created in the liver and is used to transport copper from the liver to the parts of the body that need it, including the blood.

Also Known As: Copper Oxide Test, Wilson’s Disease Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is a Ceruloplasmin test ordered?

When somebody has symptoms that a health practitioner suspects are due to Wilson disease, a ceruloplasmin test may be ordered alone or in combination with blood and 24-hour urine copper testing.

What does a Ceruloplasmin blood test check for?

Ceruloplasmin is a copper-containing enzyme that aids in iron metabolism in the body. The level of ceruloplasmin in the blood is measured with this test.

Copper is a vital mineral that regulates iron metabolism, connective tissue creation, cellular energy production, and nervous system function. The intestines absorb it from meals and liquids, and it is subsequently transferred to the liver, where it is stored or used to make a variety of enzymes.

To make ceruloplasmin, the liver binds copper to a protein and then releases it into the bloodstream. Ceruloplasmin binds about 95 percent of the copper in the blood. As a result, the ceruloplasmin test can be performed in conjunction with one or more copper tests to assist diagnose Wilson disease, a genetic illness in which the liver, brain, and other organs store too much copper.

Lab tests often ordered with a Ceruloplasmin test:

  • Copper

Conditions where a Ceruloplasmin test is recommended:

  • Wilson’s Disease
  • Liver Diseases

How does my health care provider use a Ceruloplasmin test?

Wilson disease is a rare genetic ailment characterized by excessive copper accumulation in the liver, brain, and other organs, as well as low levels of ceruloplasmin. Ceruloplasmin testing is performed in conjunction with blood and/or urine copper assays to assist diagnosis Wilson disease.

Copper is a mineral that plays an important role in the human body. Ceruloplasmin binds about 95 percent of the copper in the blood. In an unbound state, just a minimal quantity of copper is present in the blood.

A ceruloplasmin test may be ordered in conjunction with a copper test to assist diagnose problems in copper metabolism, copper deficiency, or Menkes kinky hair syndrome, a rare genetic condition.

What do my Ceruloplasmin test results mean?

Ceruloplasmin levels are frequently tested in conjunction with copper testing because they are not indicative of a specific illness.

Wilson disease can be identified by low ceruloplasmin and blood copper levels, as well as high copper levels in the urine.

About 5% of persons with Wilson disease who have neurological symptoms, as well as up to 40% of those with hepatic symptoms, especially if they are critically unwell, will have normal ceruloplasmin levels.

The person tested may have a copper deficiency if ceruloplasmin, urine, and/or blood copper values are low.

Anything that affects the body's ability to metabolize copper or the supply of copper has the potential to impact blood ceruloplasmin and copper levels.

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.

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. 

  • 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.

  • 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: Copper is a blood test that measures the amount of copper in the blood's plasma. Copper levels in the blood can help to diagnose Wilson's Disease.

Also Known As: Cu Test, Blood Copper Test, Free Copper Test, Hepatic Copper Test, Copper Serum Test, Copper Plasma Test, Copper Blood Test

Collection Method: Blood Draw

Specimen Type: Plasma or Serum

Test Preparation: No preparation required

When is a Copper test ordered?

When a health practitioner suspects Wilson disease, excess copper storage, or copper poisoning, one or more copper tests are requested along with ceruloplasmin.

When copper and ceruloplasmin results are abnormal or inconclusive, a hepatic copper test may be conducted to further evaluate copper storage.

What does a Copper blood test check for?

Copper is an important mineral that the body uses to make enzymes. These enzymes are involved in the regulation of iron metabolism, the development of connective tissue, cellular energy production, the production of melanin, and nervous system function. This test determines how much copper is present in the blood, urine, or liver.

Nuts, chocolate, mushrooms, seafood, whole grains, dried fruits, and liver are all high in copper. Copper may be absorbed into drinking water as it passes through copper pipes, and copper may be absorbed into food as it is cooked or served on copper dishes. Copper is absorbed from food or liquids in the intestines, converted to a non-toxic form by binding it to a protein, and transported to the liver in normal circumstances. To make the enzyme ceruloplasmin, the liver saves some copper and binds the remainder to another protein called apoceruloplasmin. Ceruloplasmin binds about 95 percent of the copper in the blood, with the rest attached to other proteins like albumin. In a free condition, only a little amount is present in the blood. Excess copper is excreted by the liver in the bile, which is then excreted by the body in the feces. Copper is also excreted in the urine in small amounts.

Copper excess and deficiency are uncommon. Wilson disease is a rare genetic ailment that causes the liver, brain, and other organs to store too much copper. Excess copper can arise when a person is exposed to and absorbs high amounts of copper in a short period of time or little amounts over a long period of time.

Copper deficiency can arise in patients with severe malabsorption diseases such cystic fibrosis and celiac disease, as well as infants who are exclusively fed cow-milk formulas.

Menkes kinky hair syndrome is a rare X-linked hereditary disorder that causes copper shortage in the brain and liver of affected babies. Seizures, delayed development, aberrant artery growth in the brain, and unique gray brittle kinky hair are all symptoms of the condition, which mostly affects men.

Lab tests often ordered with a Copper test:

  • Ceruloplasmin
  • Heavy Metals
  • ACTH
  • Aldosterone
  • 17-Hydroprogesterone
  • Growth Hormone

Conditions where a Copper test is recommended:

  • Wilson Disease
  • Malnutrition

How does my health care provider use a Copper test?

Copper testing is largely used to detect Wilson disease, a rare genetic ailment in which the liver, brain, and other organs accumulate an excessive amount of copper. A copper test is less usually used to detect copper excess caused by another ailment, to diagnose a copper deficit, or to track treatment for one of these conditions.

Copper is a necessary mineral, but too much of it can be harmful. The majority of it is bound to the enzyme ceruloplasmin in the blood, leaving only a little quantity "free" or unbound.

A whole blood copper test is usually ordered in conjunction with a ceruloplasmin level. If the findings of these tests are abnormal or ambiguous, a 24-hour urine copper test to monitor copper elimination and/or a copper test on a liver biopsy to check copper storage in the liver may be conducted.

A free blood copper test is sometimes ordered as well. If Wilson disease is suspected, genetic testing for mutations in the ATP7B gene may be undertaken. However, these tests are only available in a restricted number of locations and are usually carried out in specialized reference or research laboratories.

A copper test may be used to identify Menkes kinky hair syndrome, a rare inherited copper transport failure condition.

What do my Copper test results mean?

Copper test findings are frequently linked to ceruloplasmin levels and considered in context. Copper results that are abnormal are not indicative of a specific illness; rather, they signal that more research is needed. Because ceruloplasmin is an acute phase reactant, it might be raised if inflammation or severe infections are present, making interpretation difficult. Ceruloplasmin and copper levels rise during pregnancy, as well as with the use of estrogen and oral contraceptives.

Wilson disease is characterized by low blood copper concentrations, elevated urine copper levels, low ceruloplasmin levels, and increased liver copper.

Elevated copper concentrations in the blood and urine, as well as normal or increased ceruloplasmin levels, may suggest excessive copper exposure or be linked to disorders that reduce copper excretion, such as chronic liver disease, or release copper from tissues, such as acute hepatitis. Chronic diseases can cause an increase in hepatic copper levels.

Copper deficiency is indicated by lower copper concentrations in the blood and urine, as well as lower ceruloplasmin levels.

A normal hepatic copper test could mean that copper metabolism is normal, or that the distribution of copper in the liver is uneven, and that the sample isn't reflective of the person's health.

If a person is being treated for Wilson disease or copper toxicity with copper-binding medicines, their 24-hour urine copper levels may be high until their body copper stores are depleted. Copper concentrations in the blood and urine should return to normal over time.

If a person is being treated for a copper deficient disorder and their ceruloplasmin and total copper levels start to rise, the condition is likely responding to the treatment.

Description: A Ferritin test is a blood test that measures Ferritin levels in your blood’s serum to evaluate the level of iron stored in your body.

Also Known As: Ferritin Serum Test, Ferritin Test, Ferritin Blood Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is a Ferritin test ordered?

When a CBC test’s implies iron deficiency anemia due to small red blood cells or low hematocrit and hemoglobin levels, the ferritin test, and other iron tests, may be requested, even if other clinical symptoms have not yet arisen.

There are frequently no physical symptoms in the early stages of iron insufficiency. Symptoms rarely develop before hemoglobin falls below dangerous levels. However, when the iron deficit continues, symptoms emerge, prompting a doctor to order ferritin and other iron-related testing. The following are the most prevalent symptoms of iron deficiency anemia:

  • Chronic tiredness/fatigue
  • Weakness
  • Dizziness
  • Headaches
  • Skin that is pale

Shortness of breath, ringing in the ears, sleepiness, and irritability may occur as iron levels are reduced. Chest pain, headaches, limb pains, shock, and even heart failure may occur as the anemia worsens. Learning impairments can occur in children. There are some symptoms that are specific to iron deficiency, in addition to the usual signs of anemia. Pica, a burning feeling in the tongue or a smooth tongue, ulcers at the corners of the mouth, and spoon-shaped finger- and toe-nails are only a few of the symptoms.

When iron overload is suspected, a ferritin level may be requested. Iron overload symptoms differ from person to person and tend to worsen over time. They are caused by an excess of iron in the blood and tissues. Among the signs and symptoms are:

  • Joint discomfort
  • Weakness and exhaustion
  • Loss of weight
  • Energy deficiency
  • Pain in the abdomen
  • Suffering from a lack of sexual desire
  • Hair loss on the body
  • Congestive heart failure is an example of a cardiac issue

Other iron tests including a genetic test for hereditary hemochromatosis may be conducted to confirm the existence of iron excess.

What does a Ferritin blood test check for?

Ferritin is an iron-containing protein that stores iron in cells in its most basic form. The amount of total iron stored in the body is reflected in the little amount of ferritin released into the blood. This test determines how much ferritin is present in the blood.

About 70% of the iron consumed by the body is integrated into the hemoglobin of red blood cells in healthy humans. The remaining 30% is stored primarily as ferritin or hemosiderin, which is a combination of iron, proteins, and other elements. Hemosiderin and ferritin are typically found in the liver, although they can also be found in the bone marrow, spleen, and skeletal muscles.

Iron stores are depleted and ferritin levels fall when available iron is insufficient to meet the body's needs. This can happen owing to a lack of iron, poor absorption, or an increased need for iron, such as during pregnancy or if you have a condition that causes persistent blood loss. Before any indicators of iron shortage appear, significant loss of iron reserves may occur.

When the body absorbs more iron than it needs, iron storage and ferritin levels rise. Chronic iron absorption causes a gradual buildup of iron compounds in organs, which can eventually lead to organ malfunction and failure. Even on a typical diet, this happens in hemochromatosis, a hereditary disorder in which the body absorbs too much iron.

Lab tests often ordered with a Ferritin test:

  • Complete Blood Count
  • Iron Total
  • Iron Total and Total Iron binding capacity
  • Transferrin
  • Comprehensive Metabolic Panel
  • Lipid Panel
  • Zinc Protoporphyrin

Conditions where a Ferritin test is recommended:

  • Anemia
  • Hemochromatosis
  • Lead poisoning
  • Pregnancy
  • Restless Leg Syndrome

How does my health care provider use a Ferritin test?

The ferritin test is used to determine the amount of iron a person has in their body. To determine the existence and severity of iron shortage or iron overload, the test is sometimes ordered in conjunction with an iron test and a TIBC test.

One source of iron overload can be the use of iron supplements.

What does my ferritin lab test result mean?

Ferritin levels are frequently measured alongside other iron tests.

Ferritin levels are low in iron deficient people and high in people who have hemochromatosis or have had several blood transfusions.

Ferritin is an acute phase reactant that can be elevated in persons who have inflammation, liver illness, chronic infection, autoimmune disorders, or cancer. Ferritin isn't commonly utilized to detect or monitor these problems.

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

Description: A Hemoglobin (Hgb) test is a blood test that measures the amount of hemoglobin your red blood cells contain.

Also Known As: Hb Test, Hgb Test

Collection Method: Blood Draw

Specimen Type: Whole Blood

Test Preparation: No preparation required

When is a Hemoglobin test ordered?

The hemoglobin test may be requested as part of a general health assessment or when a person exhibits signs and symptoms of a red blood cell disorder such as anemia or polycythemia.

When someone has been diagnosed with recurrent bleeding difficulties, chronic anemias, or polycythemia, this test may be done numerous times or on a regular basis to check the effectiveness of treatment. It's also possible that it'll be ordered on a regular basis for those having therapy for cancers that are known to harm the bone marrow.

What does a Hemoglobin blood test check for?

Hemoglobin is an iron-containing protein found in all red blood cells, which gives them their distinctive red color. RBCs use hemoglobin to bind to oxygen in the lungs and transport it to tissues and organs all over the body. It also aids in the movement of a little amount of carbon dioxide, which is a byproduct of cell metabolism, from tissues and organs to the lungs, where it is exhaled.

The hemoglobin test determines how much hemoglobin is present in a person's blood sample. To swiftly assess an individual's red blood cells, a hemoglobin level can be used alone or in conjunction with a hematocrit, a test that assesses the fraction of blood made up of RBCs. Red blood cells, which account for roughly 40% of the amount of blood, are created in the bone marrow and released into the bloodstream when they are mature, or nearly so. RBCs have a 120-day lifespan, and the bone marrow must constantly manufacture new RBCs to replace those that have aged and degraded or have been lost due to hemorrhage.

RBCs, and thus the level of hemoglobin in the blood, can be affected by a variety of diseases and situations. When the quantity of red blood cells grows, the hemoglobin level and hematocrit both rise. When the synthesis of RBCs by the bone marrow decreases, RBC destruction increases, or blood is lost owing to hemorrhage, the hemoglobin level and hematocrit fall below normal. Anemia is a disorder in which the body's tissues and organs do not acquire enough oxygen, causing exhaustion and weakness. It is caused by a decline in RBC count, hemoglobin, and hematocrit. Polycythemia occurs when the body produces too many RBCs, causing the blood to thicken, resulting in sluggish blood flow and other complications.

Lab tests often ordered with a Hemoglobin test:

  • Complete Blood Count (CBC)
  • Hematocrit
  • Red Blood Cell Count (RBC Count)
  • Blood Smear
  • Iron Total
  • Ferritin
  • Reticulocyte Count
  • Vitamin B12
  • Folate
  • Red Cell Indices
  • G6PD
  • Erythropoietin
  • Hemoglobinopathy Evaluation

Conditions where a Hemoglobin test is recommended:

  • Anemia
  • Sickle Cell Anemia
  • Thalassemia
  • Myeloproliferative Neoplasms
  • Hemoglobin Abnormalities
  • Bone Marrow Disorders

How does my health care provider use a Hemoglobin test?

Anemia is commonly detected with a hemoglobin test in conjunction with a hematocrit or as part of a complete blood count. The test can be used to detect, diagnose, or track a variety of illnesses and disorders that impact red blood cells and/or hemoglobin levels in the blood. All red blood cells include hemoglobin, an iron-containing protein that allows RBCs to bind to oxygen in the lungs and transport it to tissues and organs throughout the body.

A hemoglobin test can be used for a variety of purposes, including:

  • Anemia and polycythemia are diagnosed, diagnosed, and measured.
  • Assess the patient's reaction to anemia or polycythemia treatment.
  • If the anemia is severe, you can help make decisions about blood transfusions or other therapies.

Some factors influence RBC production in the bone marrow, resulting in an increase or decrease in the quantity of mature RBCs discharged into the bloodstream. The longevity of RBCs in the circulation can be influenced by a variety of factors. The overall amount of RBCs and hemoglobin will diminish if there is greater destruction of RBCs or loss of RBCs through bleeding, and/or the bone marrow is unable to make new ones quickly enough, leading in anemia.

This test can tell you if you have an issue with red blood cell production or longevity, but it can't tell you what's causing it. A blood smear, reticulocyte count, iron studies, vitamin B12 and folate levels, and, in more severe cases, a bone marrow examination are some of the other tests that may be conducted at the same time or as follow-up to establish a reason.

What do my Hemoglobin test results mean?

Because hemoglobin levels are frequently measured as part of a complete blood count, the results of other components are taken into account. Hemoglobin levels must be interpreted in conjunction with other indicators such as RBC count, hematocrit, reticulocyte count, and/or red blood cell indices when they rise or fall. Other characteristics to consider are age, gender, and race. Hemoglobin reflects the RBC count and hematocrit results in general.

Anemia is defined as a low hemoglobin level combined with a low RBC count and a low hematocrit. Among the causes are:

  • Excessive blood loss-as a result of severe trauma or continuous bleeding from the digestive tract, bladder, or uterus.
  • Iron, folate, or B12 deficiency are examples of nutritional inadequacies.
  • Toxins, radiation, chemotherapy, infection, and medicines can all cause damage to the bone marrow.
  • Myelodysplastic syndrome, aplastic anemia, or tumors of the bone marrow, such as lymphoma, leukemia, multiple myeloma, or other cancers of the bone marrow
  • Renal failure—severe and chronic kidney illnesses cause the kidneys to produce less erythropoietin, a hormone that drives RBC synthesis in the bone marrow.
  • Inflammatory diseases or disorders that last a long time
  • Hemoglobin production is reduced.
  • Excessive destruction of red blood cells, such as hemolytic anemia caused by autoimmunity or faults in the red blood cell itself, such as hemoglobinopathy, RBC membrane abnormalities, or RBC enzyme.

Polycythemia is defined as a high hemoglobin level combined with a high RBC count and hematocrit. Among the causes are:

  • Lung disease-when a person's body is unable to breathe in and absorb enough oxygen. As a result, the body produces more red blood cells to compensate.
  • Congenital heart disease—in some cases, an improper connection between the two sides of the heart occurs, resulting in lower blood oxygen levels. The body responds by creating extra red blood cells in an attempt to compensate.
  • Excess erythropoietin-producing kidney tumors
  • Hemoglobin levels in heavy smokers are higher than in nonsmokers.
  • Genetic factors
  • Having to live at a high altitude
  • Dehydration causes hemoglobin to rise unnaturally when the volume of liquid in the blood declines.
  • Polycythemia vera-a rare condition in which the body creates too many RBCs.

Description: Iron and Total Iron Binding Capacity is a blood panel used to determine iron levels in your blood, your body’s ability to transport iron, and help diagnose iron-deficiency and iron overload.

Also Known As: Serum Iron Test, Serum Fe Test, Iron Binding Capacity Test, IBC Test, Serum Iron-Binding Capacity Siderophilin Test, TIBC Test, UIBC Test, Iron Lab Test, TIBC Blood test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is a Iron and Total Iron Binding Capacity test ordered?

When a doctor feels that a person's symptoms are caused by iron overload or poisoning, an iron and TIBC test, as well ferritin assays, may be done. These may include the following:

  • Joint discomfort
  • Weakness and exhaustion
  • Energy deficiency
  • Pain in the abdomen
  • Suffering from a lack of sexual desire
  • Problems with the heart

When a child is suspected of ingesting too many iron tablets, a serum iron test is required to detect the poisoning and to determine its severity.

A doctor may also request iron and TIBC when the results of a standard CBC test are abnormal, such as a low hematocrit or hemoglobin, or when a doctor suspects iron deficiency based on signs and symptoms such as:

  • Chronic tiredness/fatigue
  • Dizziness
  • Weakness
  • Headaches
  • Skin that is pale

What does a Iron and Total Iron Binding Capacity blood test check for?

Iron is a necessary ingredient for survival. It is a vital component of hemoglobin, the protein in red blood cells that binds and releases oxygen in the lungs and throughout the body. It is required in small amounts to help form normal red blood cells and is a critical part of hemoglobin, the protein in RBCs that binds oxygen in the lungs and releases it as blood circulates to other parts of the body.

By detecting numerous components in the blood, iron tests are ordered to determine the quantity of iron in the body. These tests are frequently ordered at the same time, and the data are analyzed together to determine the diagnosis and/or monitor iron deficiency or overload.

The level of iron in the liquid component of the blood is measured by serum iron.

Total iron-binding capacity is a measurement of all the proteins in the blood that may bind to iron, including transferrin.

The percentage of transferrin that has not yet been saturated is measured by the UIBC. Transferrin levels are also reflected in the UIBC.

Low iron levels can cause anemia, resulting in a decrease in the production of microcytic and hypochromic RBCs. Large amounts of iron, on the other hand, might be hazardous to the body. When too much iron is absorbed over time, iron compounds build up in tissues, particularly the liver, heart, and pancreas.

Normally, iron is absorbed from food and distributed throughout the body by binding to transferrin, a liver protein. About 70% of the iron delivered is used in the synthesis of hemoglobin in red blood cells. The rest is stored as ferritin or hemosiderin in the tissues, with minor amounts being utilized to make other proteins like myoglobin and enzymes.

Insufficient intake, limited absorption, or increased dietary requirements, as observed during pregnancy or with acute or chronic blood loss, are all signs of iron deficiency. Excessive intake of iron pills can cause acute iron overload, especially in children. Excessive iron intake, genetic hemochromatosis, multiple blood transfusions, and a few other disorders can cause chronic iron overload.

Lab tests often ordered with a Iron and Total Iron Binding Capacity test:

  • Complete Blood Count
  • Ferritin
  • Transferrin
  • Zinc Protoporphyrin

Conditions where a Iron and Total Iron Binding Capacity test is recommended:

  • Anemia
  • Hemochromatosis

How does my health care provider use a Iron and Total Iron Binding Capacity test?

The amount of circulating iron in the blood, the capacity of the blood to carry iron, and the amount of stored iron in tissues can all be determined by ordering one or more tests. Testing can also assist distinguish between different types of anemia

The level of iron in the blood is measured by serum iron.

Total iron-binding capacity is a measurement of all the proteins in the blood that may bind to iron, including transferrin. The TIBC test is a useful indirect assessment of transferrin because it is the predominant iron-binding protein. In response to the requirement for iron, the body generates transferrin. Transferrin levels rise when iron levels are low, and vice versa. About one-third of the binding sites on transferrin are used to transport iron in healthy humans.

The reserve capacity of transferrin, or the part of transferrin that has not yet been saturated, is measured by UIBC. Transferrin levels are also reflected in the UIBC.

The iron test result, as well as TIBC or UIBC, are used to calculate transferrin saturation. It represents the proportion of transferrin that is iron-saturated.

Ferritin is the major storage protein for iron inside cells, and serum ferritin represents the quantity of stored iron in the body.

These tests are frequently ordered together, and the results can assist the doctor figure out what's causing the iron deficit or overload.

Additional information about iron

A balance between the quantity of iron received into the body and the amount of iron lost is required to maintain normal iron levels. Because a tiny quantity of iron is lost each day, a deficiency will develop if too little iron is consumed. In healthy persons, there is usually enough iron to prevent iron deficiency and/or iron deficiency anemia, unless they eat a bad diet. There is a greater need for iron in some circumstances. People who have persistent gut bleeding or women who have heavy menstrual periods lose more iron than they should and can develop iron deficiency. Females who are pregnant or breastfeeding lose iron to their babies and may develop an iron shortage if they do not consume enough supplemental iron. Children may require additional iron, especially during periods of rapid growth, and may suffer iron shortage.

Low serum iron can also arise when the body is unable to adequately utilize iron. The body cannot correctly utilize iron to generate additional red cells in many chronic disorders, particularly malignancies, autoimmune diseases, and chronic infections. As a result, transferrin production slows, serum iron levels drop because little iron is absorbed from the stomach, and ferritin levels rise. Malabsorption illnesses like sprue syndrome can cause iron deficiency.

Description: A Phosphate or phosphorus test is a blood test that measures the level of phosphorus in your blood’s serum to screen for conditions associated with abnormal phosphorus levels such as kidney, liver, and bone disease.

Also Known As: Inorganic Phosphate Test, P Test, Phosphate as Phosphorus Test, Phosphorus Test, Phosphate Test, PO4 Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When is a Phosphate test ordered?

Because modestly elevated phosphorus levels normally do not induce symptoms, phosphorus testing is usually done after an abnormal calcium test and/or when signs of abnormal calcium, such as fatigue, muscle weakness, cramps, or bone issues, are evident.

When symptoms suggest kidney or gastrointestinal problems, phosphorus testing may be recommended in conjunction with other tests.

Testing for both phosphorus and calcium levels may be conducted at regular intervals to assess therapy effectiveness when problems causing abnormal phosphorus and/or calcium levels are discovered.

When a person develops diabetes or shows signs of an acid-base imbalance, their phosphorus levels may be monitored.

What does a Phosphate blood test check for?

Phosphorus is a mineral that forms organic and inorganic phosphate compounds when it reacts with other elements. When it comes to testing, the terms phosphorus and phosphate are frequently interchanged, but a serum phosphorus/phosphate test measures the amount of inorganic phosphate in the blood.

Energy production, muscle and neuron function, and bone formation all require phosphorus. They also serve as a buffer, assisting in the maintenance of the body's acid-base equilibrium.

Phosphorus enters the body through the food we eat. It can be found in a wide variety of meals and is quickly absorbed by the intestines. About 70-80 percent of the phosphates in the body combine with calcium to help build bones and teeth, another 10% is located in muscle, and about 1% is found in nerve tissue. The rest can be found in cells all across the body, where they are mostly employed to store energy.

In normal circumstances, only about 1% of total body phosphates are found in the blood. Phosphorus is found in a wide range of foods, including beans, peas, and almonds, cereals, dairy products, eggs, meat, poultry, and fish. The body regulates how much phosphorus/phosphate it takes from the intestines and how much it excretes through the kidneys to maintain phosphorus/phosphate levels in the blood. The combination of parathyroid hormone, calcium, and vitamin D affects phosphate levels as well.

Malnutrition, malabsorption, acid-base imbalances, hypercalcemia, and illnesses that impact kidney function can all cause phosphorus shortages. Phosphorus excesses can occur as a result of high phosphorus ingestion, hypocalcemia, or kidney disease.

Often, a person with a mild to severe phosphorus deficit has no symptoms. Muscle weakness and disorientation are common symptoms of severe phosphorus insufficiency. Muscle cramps, confusion, and even convulsions can be caused by a severe excess of phosphorus, which is comparable to the symptoms of low calcium.

Lab tests often ordered with a Phosphate test:

  • Calcium
  • Complete Blood Count
  • Iron Total
  • Iron Total and Total Iron binding capacity
  • Magnesium
  • Comprehensive Metabolic Panel
  • Vitamin D
  • Parathyroid Hormone

Conditions where a Phosphate test is recommended:

  • Kidney Disease
  • Diabetes
  • Acidosis
  • Alkalosis
  • Hyperparathyroidism
  • Hypoparathyroidism
  • Malnutrition
  • Alcoholism
  • Hypothyroidism

How does my health care provider use a Phosphate test?

Phosphorus tests are frequently requested in conjunction with other tests, such as calcium, parathyroid hormone, and/or vitamin D, to aid in the diagnosis and/or monitoring of various calcium and phosphorus abnormalities.

While phosphorus tests are most typically done on blood samples, urine samples are sometimes used to evaluate phosphorus clearance by the kidneys.

What does my Phosphorus test result mean?

Hypophosphatemia can be caused by or linked to:

  • Hypercalcemia 
  • Diuretics overuse
  • Malnutrition
  • Alcoholism
  • Burns that are severe
  • Ketoacidosis in diabetics
  • Hypothyroidism
  • Hypokalemia
  • Use of antacids on a regular basis
  • Rickets and osteomalacia

Hyperphosphatemia can be caused by or linked to:

  • Failure of the kidneys
  • Hepatitis
  • Hypoparathyroidism
  • Ketoacidosis in diabetics
  • Phosphate supplementation

Measurement of serum 25-OH vitamin D concentrations provide a good index of circulating vitamin D activity in patients not suffering from renal disease. Lower than normal 25-OH vitamin D levels can result from a dietary deficiency, poor absorption of the vitamin or impaired metabolism of the sterol in the liver. A 25-OH vitamin D deficiency can lead to bone diseases such as rickets and osteomalacia. Above normal levels can lead hypercalcemia. This assay employs liquid chromatography tandem mass spectrometry to independently measure and report the two common forms of 25-hydroxy vitamin D: 25OH D3 - the endogenous form of the vitamin and 25OH D2 - the analog form used to treat 25OH Vitamin D3 deficiency. While this assay will produce accurate Vitamin D results on patients of any age, it is specifically indicated for infants less than 3 years of age.



How often do you think about your mineral levels? 

Unless you're a professional athlete, doctor, or nutritionist, it probably doesn't cross your mind more than once a year at your annual physical. If you're taking a multivitamin, that's even better than most!

Magnesium is crucial to the body's muscle, hormonal, and nerve function. Without it, you're likely feeling tired, crampy, and anxious. You may have a hard time focusing and struggle to sleep, digest meals, or enjoy sex. 

Magnesium blood tests are the first look into what your body may be lacking. Read on to understand how magnesium deficiency feels and how the correct magnesium deficiency test can start you on the right track to functional healing.   

Risk Factors For Magnesium Deficiency 

Some populations are at a higher risk for magnesium deficiency. These include: 

  • Diabetics
  • Those with an unhealthy diet 
  • Pregnant women
  • Those taking medications that inhibit magnesium stores in the body 
  • Those with vitamin D deficiency 
  • Those with gastrointestinal conditions
  • Alcoholics

If you fall under any of these groups, it might be worth getting tested.  

Causes of Magnesium Deficiency 

Magnesium deficiency is caused by the body's inability to properly absorb the mineral in the gut or excess magnesium loss through the body's waste. In addition, kidney problems may affect magnesium excretion, as it is the kidney's responsibility to determine optimal levels in the body. 

Magnesium levels are also known to take a hit during pregnancy.  

Nutrition lacking in essential vitamins and minerals may also affect magnesium levels. 

Signs and Symptoms of Magnesium Deficiency

Magnesium is a metabolic necessity in our bodies. It's needed in optimal amounts for your bones, muscles, nerves, digestive tract, hormones, blood sugar, and heart. 

Magnesium deficiency can range from barely noticeable to extremely uncomfortable. Signs and symptoms of magnesium deficiency include: 

  • Muscle cramping
  • Depression and anxiety 
  • Osteoporosis 
  • Fatigue and poor sleep 
  • High blood pressure and heart arrhythmia 
  • Poor appetite
  • Nausea 
  • Weakness 
  • Headaches
  • Low levels of other minerals - like calcium and potassium 

Having any one of a few of these symptoms may not necessarily point to a deficiency. It will take a lab test to determine if you are. 

Lab Tests for Magnesium Deficiency  

Your doctor will require a magnesium deficiency lab test to screen, diagnose and monitor your condition. To confirm that you are magnesium deficient, a doctor may request a urine sample, though a blood test is most efficient. 

A magnesium deficiency test is also known as a serum magnesium test. Its purpose is to measure the amount of magnesium in the blood–-though a majority of the body's magnesium stores are found in the bones. 

You can initiate your blood draw from one of 2,100 state and federally certified blood-draw centers near your home. Once your specimen is collected, it is sent to Quest Diagnostics to process, and your results will be available for you to view on your Ulta Lab Tests dashboard.

An optimal blood (serum) magnesium level is is 1.8 to 2.2 milligrams per deciliter (mg/dL). Anything lower than this range may be diagnosed by your doctor as hypomagnesemia and will need an immediate treatment plan.
