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 

Average Processing Time: 1 to 2 days

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: Ulta Lab Tests provides CBC test results from Quest Diagnostics as they are reported. Often, different biomarker results are made available at different time intervals. When reporting the results, Ulta Lab Tests denotes those biomarkers not yet reported as 'pending' for every biomarker the test might report. Only biomarkers Quest Diagnostics observes are incorporated and represented in the final CBC test results provided by Ulta Lab Tests. 

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.

Reflex Parameters for Manual Slide Review

CBC Reflex Pathway

Step 1 - The slide review is performed by qualified Laboratory staff and includes:

• Confirmation of differential percentages
• WBC and platelet estimates, when needed
• Full review of RBC morphology
• Comments for toxic changes, RBC inclusions, abnormal lymphs, and other
• significant findings
• If the differential percentages agree with the automated counts and no abnormal cells are seen, the automated differential is reported with appropriate comments

Step 2 - The slide review is performed by qualified Laboratory staff and includes: If any of the following are seen on the slide review, Laboratory staff will perform a manual differential:

• Immature, abnormal, or toxic cells
• nRBC’s
• Disagreement with automated differential
• Atypical/abnormal RBC morphology
• Any RBC inclusions

Step 3 - If any of the following are seen on the manual differential, a Pathologist will review the slide:

• WBC<1,500 with abnormal cells noted
• Blasts/immature cells, hairy cell lymphs, or megakaryocytes
• New abnormal lymphocytes or monocytes
• Variant or atypical lymphs >15%
• Blood parasites
• RBC morphology with 3+ spherocytes, RBC inclusions, suspect Hgb-C,
• crystals, Pappenheimer bodies or bizarre morphology
• nRBC’s

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.

Average Processing Time: 1 to 2 days 

When is a Comprehensive Metabolic Panel test ordered:  

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

What does a Comprehensive Metabolic Panel blood test check for? 

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

The following tests are included in the CMP: 

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Lab tests often ordered with a Comprehensive Metabolic Panel test: 

• Complete Blood Count with Differential and Platelets
• Iron and Total Iron Binding Capacity
• Lipid Panel
• Vitamin B12 and Folate
• Prothrombin with INR and Partial Thromboplastin Times
• 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 cortisol test measures the amount of cortisol in the blood. These levels will start off high in the morning and throughout the say they become lower. At midnight they are typically at their lowest level. Someone who works a night shift or has an irregular sleep schedule may have a different pattern. This test can be used to determine Cushing's or Addison's Disease.

Also Known As: Cortisol AM Test, Cortisol Total Test, Cortisol Test, Cortisol Blood Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: Specimen must be drawn between 7 a.m. and 9 a.m. Test is not recommended for patients receiving prednisone/prednisolone therapy due to cross reactivity with the antibody used in this test.

Average Processing Time: 1 to 2 days

When is a Cortisol AM test ordered?

When a person has symptoms that point to a high level of cortisol and Cushing syndrome, a cortisol test may be recommended.

Women with irregular menstrual periods and increased facial hair may be tested, and children with delayed development and small stature may also be tested.

When someone exhibits symptoms that point to a low cortisol level, adrenal insufficiency, or Addison disease, this test may be ordered.

What does a Cortisol AM blood test check for?

Cortisol is a hormone that plays a function in protein, lipid, and carbohydrate metabolism. It has an effect on blood glucose levels, blood pressure, and immune system regulation. Only a small fraction of cortisol in the blood is "free" and biologically active; the majority is attached to a protein. Cortisol is a hormone that is produced into the urine and found in the saliva. This test determines how much cortisol is present in the blood, urine, or saliva.

Cortisol levels in the blood usually rise and fall in a pattern known as "diurnal variation." It reaches its highest point early in the morning, then gradually decreases over the day, reaching its lowest point around midnight. When a person works irregular shifts and sleeps at different times of the day, this rhythm might fluctuate, and it can be disrupted when a disease or condition inhibits or stimulates cortisol production.

The adrenal glands, two triangle organs that sit on top of the kidneys, generate and emit cortisol. The hypothalamus in the brain and the pituitary gland, a small organ below the brain, control the hormone's production. The hypothalamus produces corticotropin-releasing hormone when blood cortisol levels drop, which tells the pituitary gland to create ACTH. The adrenal glands are stimulated by ACTH to generate and release cortisol. A certain amount of cortisol must be produced for normal adrenal, pituitary gland, and brain function.

Cushing syndrome is a collection of signs and symptoms associated with an unusually high cortisol level. Cortisol production may be increased as a result of:

• Large doses of glucocorticosteroid hormones are given to treat a range of ailments, including autoimmune illness and certain cancers.
• Tumors that produce ACTH in the pituitary gland and/or other regions of the body.
• Cortisol production by the adrenal glands is increased as a result of a tumor or abnormal expansion of adrenal tissues.

Rarely, CRH-producing malignancies in various regions of the body.

Cortisol production may be reduced as a result of:

• Secondary adrenal insufficiency is caused by an underactive pituitary gland or a pituitary gland tumor that prevents ACTH production.
• Primary adrenal insufficiency, often known as Addison disease, is characterized by underactive or injured adrenal glands that limit cortisol production.

After quitting glucocorticosteroid hormone medication, especially if it was abruptly stopped after a long time of use.

Lab tests often ordered with a Cortisol AM test:

• Cortisol PM
• ACTH
• Aldosterone
• 17-Hydroxyprogesterone
• Growth Hormone

Conditions where a Cortisol AM test is recommended:

• Addison’s Disease
• Cushing’s Syndrome
• Endocrine Syndromes
• Hypertension
• Pituitary Disorders

How does my health care provider use a Cortisol AM test?

A cortisol test can be used to detect Cushing syndrome, which is characterized by an excess of cortisol, as well as adrenal insufficiency or Addison disease, which are characterized by a deficiency of cortisol. Among other things, the hormone cortisol controls how proteins, lipids, and carbohydrates are metabolized. Cortisol levels in the blood normally increase and fall in a "diurnal variation" pattern, rising early in the morning, dropping during the day, and reaching their lowest point around midnight.

The adrenal glands generate and excrete cortisol. The hypothalamus in the brain and the pituitary gland, a small organ below the brain, control the hormone's production. The hypothalamus produces corticotropin-releasing hormone when blood cortisol levels drop, which tells the pituitary gland to create ACTH. Cortisol production and release are triggered by ACTH in the adrenal glands. A certain amount of cortisol must be produced for normal brain, pituitary, and adrenal gland function.

Only a small fraction of cortisol in the blood is "free" and biologically active; the majority is attached to a protein. Blood cortisol testing assesses both protein-bound and free cortisol, but urine and saliva cortisol testing assesses only free cortisol, which should be in line with blood cortisol levels. Multiple blood and/or saliva cortisol levels collected at various times, such as 8 a.m. and 4 p.m., can be used to assess cortisol levels and diurnal variation. A 24-hour urine cortisol sample will not reveal diurnal variations; instead, it will assess the total quantity of unbound cortisol voided over the course of 24 hours.

If an elevated amount of cortisol is found, a health professional will conduct additional tests to confirm the results and discover the cause.

If a person's blood cortisol level is abnormally high, a doctor may order additional tests to be sure the high cortisol is indeed abnormal. Additional testing could involve monitoring 24-hour urinary cortisol, doing an overnight dexamethasone suppression test, and/or obtaining a salivary sample before sleep to detect cortisol at its lowest level. Urinary cortisol testing necessitates collecting urine over a set length of time, usually 24 hours. Because ACTH is released in pulses by the pituitary gland, this test can assist evaluate whether a raised blood cortisol level is a true rise.

An ACTH stimulation test may be ordered if a health practitioner feels that the adrenal glands are not releasing enough cortisol or if initial blood tests reveal insufficient cortisol production.

The purpose of ACTH stimulation is to compare the levels of cortisol in a person's blood before and after receiving an injection of synthetic ACTH. If the adrenal glands are healthy, the reaction to ACTH stimulation will be an increase in cortisol levels. Low amounts of cortisol will result if they are broken or not functioning properly. To distinguish between adrenal and pituitary insufficiency, a lengthier variant of this test can be used.

What do my Cortisol AM test results mean?

Cortisol levels are typically lowest before bedtime and highest shortly after awakening, though this pattern can be disrupted if a person works rotating shifts and sleeps at various times on separate days.

Excess cortisol and Cushing syndrome are indicated by an increased or normal cortisol level shortly after awakening, as well as a level that does not diminish by bedtime. If the excess cortisol is not suppressed after an overnight dexamethasone suppression test, the 24-hour urine cortisol is elevated, or the late-night salivary cortisol level is elevated, the excess cortisol is likely due to abnormal increased ACTH production by the pituitary or a tumor outside of the pituitary, or abnormal production by the adrenal glands. Additional tests will aid in determining the root of the problem.

If the subject of the examination reacts to an ACTH stimulation test and has insufficient cortisol levels, the issue is most likely brought on by the pituitary's insufficient production of ACTH. The adrenal glands are most likely the source of the issue if the subject does not react to the ACTH stimulation test.

An additional test, like as a CT scan, may be used by the medical professional to evaluate the degree of any gland damage once an irregularity has been identified and related to the pituitary gland, the adrenal glands, or another cause.

Important: Patient needs to have the specimen collected between 7 a.m.-9 a.m.

The adrenal glands are stimulated by ACTH to generate and release cortisol. The brain, pituitary, and adrenal glands must all be operating properly in order to produce enough levels of cortisol.

Only a small fraction of cortisol in the blood is "free" and biologically active; the majority is attached to a protein. Blood cortisol testing assesses both protein-bound and free cortisol, but urine and saliva cortisol testing assesses only free cortisol, which should be in line with blood cortisol levels. Multiple blood and/or saliva cortisol levels collected at various times, such as 8 a.m. and 4 p.m., can be used to assess cortisol levels and diurnal variation. A 24-hour urine cortisol sample will not reveal diurnal variations; instead, it will assess the total quantity of unbound cortisol voided over the course of 24 hours.

If an elevated amount of cortisol is found, a health professional will conduct additional tests to confirm the results and discover the cause.

If a person's blood cortisol level is abnormally high, a doctor may order additional tests to be sure the high cortisol is indeed abnormal. Additional testing could involve monitoring 24-hour urinary cortisol, doing an overnight dexamethasone suppression test, and/or obtaining a salivary sample before sleep to detect cortisol at its lowest level. Urinary cortisol testing necessitates collecting urine over a set length of time, usually 24 hours. Because ACTH is released in pulses by the pituitary gland, this test can assist evaluate whether a raised blood cortisol level is a true rise.

An ACTH stimulation test may be ordered if a health practitioner feels that the adrenal glands are not releasing enough cortisol or if initial blood tests reveal insufficient cortisol production.

ACTH stimulation is a test that measures the amount of cortisol in a person's blood before and after a synthetic ACTH injection. Cortisol levels will rise in response to ACTH stimulation if the adrenal glands are functioning normally. Cortisol levels will be low if they are damaged or not working properly. To distinguish between adrenal and pituitary insufficiency, a lengthier variant of this test can be used.

What do my Cortisol PM test results mean?

Cortisol levels are typically lowest before bedtime and highest shortly after awakening, though this pattern can be disrupted if a person works rotating shifts and sleeps at various times on separate days.

Excess cortisol and Cushing syndrome are indicated by an increased or normal cortisol level shortly after awakening, as well as a level that does not diminish by bedtime. If the excess cortisol is not suppressed after an overnight dexamethasone suppression test, the 24-hour urine cortisol is elevated, or the late-night salivary cortisol level is elevated, the excess cortisol is likely due to abnormal increased ACTH production by the pituitary or a tumor outside of the pituitary, or abnormal production by the adrenal glands. Additional tests will aid in determining the root of the problem.

If the person examined responds to an ACTH stimulation test and has insufficient cortisol, the problem is most likely due to insufficient ACTH production by the pituitary. If the person does not respond to the ACTH stimulation test, the problem is most likely to be with the adrenal glands. Secondary adrenal insufficiency occurs when the adrenal glands are underactive as a result of pituitary dysfunction and/or insufficient ACTH synthesis. Adrenal injury causes decreased cortisol production, which is referred to as primary adrenal insufficiency or Addison disease.

Once an irregularity has been found and linked to the pituitary gland, adrenal glands, or another source, the health practitioner may utilize additional testing, such as a CT scan, to determine the extent of any gland damage.

Patient needs to have the specimen collected between 3 p.m - 5 p.m.

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

Description: A cortisol test measures the amount of cortisol in the blood. These levels will start off high in the morning and throughout the say they become lower. At midnight they are typically at their lowest level. Someone who works a night shift or has an irregular sleep schedule may have a different pattern. This test can be used to determine Cushing's or Addison's Disease.

Also Known As: Cortisol Total Test, Cortisol Test, Cortisol Blood Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: Test not recommended when patient is on prednisone/prednisolone therapy due to cross reactivity with the antibody used in this test

Average Processing Time: 1 to 2 days

When is a Cortisol Total test ordered?

When a person has symptoms that point to a high level of cortisol and Cushing syndrome, a cortisol test may be recommended.

Women with irregular menstrual periods and increased facial hair may be tested, and children with delayed development and small stature may also be tested.

When someone exhibits symptoms that point to a low cortisol level, adrenal insufficiency, or Addison disease, this test may be ordered.

What does a Cortisol Total blood test check for?

Cortisol is a hormone that plays a function in protein, lipid, and carbohydrate metabolism. It has an effect on blood glucose levels, blood pressure, and immune system regulation. Only a small fraction of cortisol in the blood is "free" and biologically active; the majority is attached to a protein. Cortisol is a hormone that is produced into the urine and found in the saliva. This test determines how much cortisol is present in the blood, urine, or saliva.

Cortisol levels in the blood usually rise and fall in a pattern known as "diurnal variation." It reaches its highest point early in the morning, then gradually decreases over the day, reaching its lowest point around midnight. When a person works irregular shifts and sleeps at different times of the day, this rhythm might fluctuate, and it can be disrupted when a disease or condition inhibits or stimulates cortisol production.

The adrenal glands, two triangle organs that sit on top of the kidneys, generate and emit cortisol. The hypothalamus in the brain and the pituitary gland, a small organ below the brain, control the hormone's production. The hypothalamus produces corticotropin-releasing hormone when blood cortisol levels drop, which tells the pituitary gland to create ACTH. The adrenal glands are stimulated by ACTH to generate and release cortisol. The brain, pituitary, and adrenal glands must all be operating properly in order to produce enough levels of cortisol.

Cushing syndrome is a collection of signs and symptoms associated with an unusually high cortisol level. Cortisol production may be increased as a result of:

• Large doses of glucocorticosteroid hormones are given to treat a range of ailments, including autoimmune illness and certain cancers.
• Tumors that produce ACTH in the pituitary gland and/or other regions of the body.
• Cortisol production by the adrenal glands is increased as a result of a tumor or abnormal expansion of adrenal tissues.

Rarely, CRH-producing malignancies in various regions of the body.

Cortisol production may be reduced as a result of:

• Secondary adrenal insufficiency is caused by an underactive pituitary gland or a pituitary gland tumor that prevents ACTH production.
• Primary adrenal insufficiency, often known as Addison disease, is characterized by underactive or injured adrenal glands that limit cortisol production.

After quitting glucocorticosteroid hormone medication, especially if it was abruptly stopped after a long time of use.

Lab tests often ordered with a Cortisol Total test:

• Cortisol PM
• Cortisol AM
• Cortisol Saliva
• ACTH
• Aldosterone
• 17-Hydroxyprogesterone
• Growth Hormone

Conditions where a Cortisol Test is recommended:

• Addison’s Disease
• Cushing’s Syndrome
• Endocrine Syndromes
• Hypertension
• Pituitary Disorders

How does my health care provider use a Cortisol Total test?

A cortisol test can be used to detect Cushing syndrome, which is characterized by an excess of cortisol, as well as adrenal insufficiency or Addison disease, which are characterized by a deficiency of cortisol. Cortisol is a hormone that regulates protein, lipid, and carbohydrate metabolism, among other functions. Cortisol levels in the blood normally increase and fall in a "diurnal variation" pattern, rising early in the morning, dropping during the day, and reaching their lowest point around midnight.

Brief Description: DHEA Sulfate is a blood test that is measuring the levels of Dehydroepiandrosterone Sulfate in the blood. It is often used to diagnose any problems in the adrenal glands such as cancer or a tumor. It can also be used to evaluate the cause of early puberty in young boys and male characteristics or appearance in women.

Also Known As: DHEA-SO4 Test, DHEAS Test, DHES1 Test, Dehydroepiandrosterone Sulfate Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

Average Processing Time: 2 to 3 days

When is a DHEA Sulfate test ordered?

When excess androgen production is suspected and/or a health practitioner wants to analyze a person's adrenal gland function, a DHEAS test, along with other hormone testing, may be requested.

It can be assessed when a woman exhibits signs and symptoms of amenorrhea, infertility, and/or virilization. The intensity of these alterations varies, but they may include:

• A huskier voice
• Hair on the face or on the body that is excessive
• Baldness in men
• Muscularity
• Acne
• The Adam's apple has been enlarged
• Breast size has shrunk

It may also be ordered if a young girl exhibits evidence of virilization or if a female infant's external genitalia are not clearly male or female.

When young males show indicators of premature puberty, such as a deeper voice, pubic hair, muscularity, and an enlarged penis before the age of typical puberty, DHEAS may be evaluated.

What does a DHEA Sulfate blood test check for?

Male sex hormone dehydroepiandrosterone sulfate is found in both men and women. This test determines the amount of DHEAS in your blood.

DHEAS:

• At puberty, it aids in the development of male secondary sexual traits.
• Can be transformed into more strong androgens like testosterone and androstenedione by the body.
• It has the ability to transform into estrogen.

DHEAS is almost entirely produced by the adrenal glands, with minor contributions from a woman's ovaries and a man's testicles.

It's a good indicator of how well the adrenal glands are working. Overproduction of DHEAS can be caused by malignant and non-cancerous adrenal tumors, as well as adrenal hyperplasia. DHEAS can be produced by an ovarian tumor in rare cases.

DHEAS excess:

• In adult men, it may go unnoticed.
• In young boys, it can cause early puberty.
• Menstrual irregularities and the development of masculine physical traits in girls and women, such as excess body and facial hair
• Can result in a female infant being born with genitals that aren't clearly male or female

Lab tests often ordered with a DHEA Sulfate test:

• Testosterone
• ACTH
• FSH
• LH
• Prolactin
• Estrogen
• Estradiol
• Sex Hormone Binding Globulin
• 17-Hydroxyprogesterone
• Androstenedione

Conditions where a DHEA Sulfate test is recommended:

• PCOS
• Infertility
• Endocrine Syndromes
• Adrenal Insufficiency
• Congenital Adrenal Hyperplasia

How does my health care provider use a DHEA Sulfate test?

The dehydroepiandrosterone sulfate test is ordered in conjunction with testosterone and other male hormones assays to:

• Examine the adrenal glands' performance.
• Differentiate DHEAS-secreting disorders produced by the adrenal glands from those caused by the testicles or, in rare cases, the ovaries
• Adrenocortical tumors and adrenal malignancies can be diagnosed with this test.
• Assist in the diagnosis of congenital and adult-onset adrenal hyperplasia.

DHEAS levels are frequently examined in women, along with other hormones like FSH, LH, prolactin, estrogen, and testosterone, to help diagnose polycystic ovarian syndrome and rule out other reasons of infertility, lack of monthly cycle, and excess facial and body hair.

DHEAS levels, along with other hormones, may be requested to examine and diagnose the cause of young females developing masculine physical traits and young boys developing early puberty.

What do my DHEA-S test results mean?

A normal DHEAS level, together with other normal male hormone levels, suggests that the adrenal gland is working properly. When an adrenal tumor or cancer is present but not secreting hormones, DHEAS may be normal.

A high DHEAS blood level could indicate that the person's symptoms are caused or exacerbated by excessive DHEAS production. An elevated level of DHEAS, on the other hand, is not used to make a diagnosis of any particular condition; rather, it usually signals that further testing is required to determine the source of the hormone imbalance. An adrenocortical tumor, Cushing illness, adrenal cancer, or adrenal hyperplasia, as well as a DHEAS-producing ovarian tumor, can all cause high DHEAS.

DHEAS levels may be high in polycystic ovary syndrome, but they may also be normal, as PCOS is usually associated with ovarian androgen production.

Adrenal insufficiency, adrenal dysfunction, Addison disease, or hypopituitarism, a disorder characterized by low levels of pituitary hormones that govern the generation and secretion of adrenal hormones, can all produce low DHEAS levels.

Description: Estradiol is a blood test that is used to measure the levels of Estradiol in the blood's serum. Estradiol is one of the Estrogen hormones in the body.  Estradiol, Ultrasensitive LC/MS/MS #30289 is a more appropriate test for children that have not yet started a menstrual cycle.

Also Known As: E2 Test, Estrogen 2 Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

Average Processing Time: 1 to 2 days

When is an Estradiol test ordered?

Tests for estradiol for women may be ordered if:

• After menopause, a woman may experience symptoms such as abnormal vaginal bleeding or irregular or absent menstrual cycles.
• When a woman is unable to conceive, a series of estradiol readings taken over the course of her menstrual cycle may be used to track follicle development before using in vitro fertilization procedures
• A woman is experiencing menopause symptoms such as hot flashes, night sweats, sleeplessness, and/or irregular or absent menstrual cycles.
• If a menopausal woman is on hormone replacement therapy, her doctor may order estrone levels on a regular basis to check her progress.

Men and young boys may be subjected to estradiol testing if:

• A boy's puberty is delayed, as evidenced by slow or delayed growth of testicles and penis, as well as a lack of deepening of voice or growth of body hair.
• Signs of feminization, such as larger breasts.

What does an Estradiol blood test check for?

Estradiol, or E2, is a component of Estrogen that is present in the blood. For women, Estradiol is something that should be produced naturally, and the body produces larger amounts of Estradiol during puberty and it fluctuates throughout the menstrual cycle. Estradiol is most prominent in women of reproductive age. Low levels are common in girls who have not yet had their first menstrual cycle and in women after their reproductive age.

Lab tests often ordered with an Estradiol test:

• Estrogen, Total, Serum
• Estriol
• Estrone
• Testosterone Free and Total

Conditions where an Estradiol test is recommended:

• Infertility
• Menopause
• Polycystic Ovarian Syndrome
• Hormone Imbalance
• Premature, delayed, or abnormal development of sex organs

Commonly Asked Questions:

How does my health care provider use an Estradiol test?

Estrogen tests are used to detect a deficit or excess of estrogen in a woman, as well as to aid in the diagnosis of a range of illnesses linked to this imbalance. They may also be ordered to monitor the health of the growing fetus and placenta during pregnancy, as well as to help predict the timing of a woman's ovulation. Estrogen testing can be used to detect a hormone excess and its origin in men.

In the case of girls and women

Estradiol testing may be requested for the following reasons:

• Diagnose early-onset puberty, which occurs when a girl develops secondary sex traits much earlier than anticipated, or late puberty, which occurs when a female develops secondary sex characteristics or begins menstruation later than predicted.
• Examine menstrual irregularities such as the absence of menstrual periods, infertility, and unusual vaginal bleeding.
• Evaluate ovary function and look for signs of ovarian failure.
• Serial measurements of estradiol can be used to track follicle development in the ovary in the days leading up to in vitro fertilization.
• Keep track of any hormone replacement therapy you're getting to help with your fertility.
• Keep track of menopausal hormone replacement medication, which is used to treat symptoms caused by estrogen insufficiency.
• Identify cancers that produce estrogen.
• As with breast cancer, keep an eye on anti-estrogen therapy.

Boys and men may be subjected to estradiol testing in order to:

• Assist in the diagnosis of delayed puberty
• Assist in determining the cause of larger breasts or other feminization indications.
• Detect an excess of relative estrogen due to a testosterone or androgen deficit.
• Identify cancers that produce estrogen.

What do my Estradiol test results mean?

Estradiol is one of the three Estrogens that have a large impact on the women's body throughout the menstrual cycle. When these hormones are too high or too low, it could cause irregular bleeding, infertility, complications with menopause, and delayed or premature puberty. Out of range levels can also be indicative of an ovarian condition such as PCOS. It is important to note that these values will fluctuate throughout a woman's cycle. The Estrogen hormones work together and if one is out of range, the others may also be out of range. It is recommended to follow up with a licensed healthcare professional to determine the best treatment if need.

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

IMPORTANT - Note this Estradiol test is not for children that have yet to start their menstrual cycle.  If this test is ordered for a child that has yet to begin their menstrual cycle Quest Diagnostics labs will substitute in Estradiol, Ultrasensitive LC/MS/MS - #30289 at an additional charge of $34

Description: A Follicle Stimulating Hormone, or FSH, test is a blood test that measures the levels of FSH in the blood. This can be used to diagnose conditions related to the sex organs, early or late puberty, or a condition affecting the pituitary or hypothalamus. It is also used to predict ovulation, evaluate infertility and monitor during infertility treatment. Levels that are out of range can help, along with several other hormone test, to evaluate the cause of irregular menstrual cycles.

Also Known As: Follicle Stimulating Hormone Test, Follitropin Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

Average Processing Time: 1 to 2 days

When is a FSH test ordered?

An FSH test may be recommended for a woman if she is having trouble conceiving or has irregular or absent menstrual periods.

When a woman's menstrual cycle has ended or grown erratic, FSH may be ordered to see if she has entered menopause.

When a man's spouse is unable to conceive, when he has a low sperm count, or when he has low muscle mass or diminished sex drive, for example, the test may be ordered.

When a health care provider detects a pituitary issue in a woman or a man, testing may be ordered. Because a pituitary problem can disrupt the production of a variety of hormones, other signs and symptoms may appear in addition to those described above. Fatigue, weakness, unexpected weight loss, and decreased appetite are just a few examples.

When a boy or girl does not seem to be entering puberty at the proper age, FSH and LH may be prescribed. Puberty symptoms include:

• Breast enlargement in young women
• Pubic hair development
• In boys, the testicles and penis grow.
• In girls, menstruation begins.

What does a FSH blood test check for?

FSH is a hormone linked to production and the development of eggs and sperm in both men and women. FSH is measured in the blood.

The pituitary gland, a grape-sized structure near the base of the brain, produces FSH. The hypothalamus in the brain, the pituitary gland, and hormones generated by the ovaries or testicles all work together to control FSH production. The hypothalamus secretes gonadotropin-releasing hormone, which causes the pituitary to secrete FSH and luteinizing hormone, a hormone that is closely related to FSH and is also important in reproduction.

During the follicular phase of the menstrual cycle, FSH increases the growth and maturation of eggs in the ovaries in women. The menstrual cycle is divided into two phases: follicular and luteal, each lasting approximately 14 days. During this follicular phase, FSH triggers the follicle's synthesis of estradiol, and the two hormones collaborate to help the egg follicle develop further. A surge of FSH and luteinizing hormone occurs near the end of the follicular period. Shortly after this burst of hormones, the egg is released from the ovary. The hormones inhibin, estradiol, and progesterone all help the pituitary gland regulate the quantity of FSH released. FSH also improves the ovary's ability to respond to LH.

Ovarian function declines and eventually quits as a woman matures and approaches menopause. FSH and LH levels rise as a result of this.

FSH induces the development of mature sperm in men's testicles, as well as the production of androgen binding proteins. After adolescence, men's FSH levels remain rather steady.

FSH levels rise early after birth in infants and children, then fall to very low levels by 6 months in boys and 1-2 years in girls. Prior to the onset of puberty and the development of secondary sexual characteristics, concentrations begin to rise again.

The production of too much or too little FSH can be caused by disorders affecting the brain, pituitary, ovaries, or testicles, resulting in infertility, irregular menstrual cycles, or early or delayed sexual development.

Lab tests often ordered with a FSH test:

• Estrogen
• Estradiol
• LH
• Testosterone
• Progesterone
• Androstenedione
• Sperm Analysis
• Anti-Mullerian Hormone
• Prolactin
• Sex Hormone Binding Globulin

Conditions where a FSH test is recommended:

• Infertility
• Menopause
• Pituitary Disorders
• Endocrine Syndromes
• PCOS

How does my health care provider use a FSH test?

There are various applications for the follicle-stimulating hormone test, which is a hormone linked to reproduction and the development of eggs in women and sperm in men.

The test can be used with additional hormone assays including luteinizing hormone, testosterone, estradiol, and/or progesterone in both women and men to help:

• Find out what's causing infertility.
• Diagnose conditions involving ovarian or testicular dysfunction.
• Aid in the diagnosis of diseases of the pituitary or hypothalamus, which can impact FSH production.

FSH levels are also relevant in women for:

• Menstrual irregularities are being investigated.
• Menopause start or confirmation prediction

FSH levels in males are used to determine the cause of a low sperm count.

FSH and LH are used to diagnose delayed or precocious puberty in children. Puberty timing irregularities could indicate a more significant disease involving the hypothalamus, pituitary gland, ovaries, testicles, or other systems. LH and FSH levels can help distinguish between benign symptoms and real disease. Once it's been determined that the symptoms are due to an actual condition, more testing can be done to figure out what's causing them.

What do my FSH test results mean?

FSH test findings are frequently combined with those from other hormone testing, such as LH, estrogens, and/or testosterone.

A high or low FSH level as part of an infertility workup is not diagnostic, but it does provide some insight into the cause. A hormone imbalance, for example, can influence a woman's menstrual cycle and/or ovulation. To make a diagnosis, a doctor will take into account all of the information gathered during the examination.

Women's Health

FSH and LH levels can assist distinguish between primary ovarian failure and secondary ovarian failure.

Primary ovarian failure is associated with high levels of FSH and LH.

Low FSH and LH levels are indicative of secondary ovarian failure caused by a pituitary or hypothalamic issue. Low FSH levels in the blood have been linked to an increased risk of ovarian cancer.

Men's Health

Primary testicular failure causes high FSH levels. As shown below, this can be the result of developmental problems in testicular growth or testicular damage.

Low levels are indicative of pituitary or hypothalamic dysfunction.

Children's Health

Precocious puberty is defined by high levels of FSH and LH, as well as the development of secondary sexual traits at an extremely young age. This occurs far more frequently in girls than in boys. This abnormal development is usually caused by a problem with the central nervous system, which can have a variety of causes.

Normal prepubescent LH and FSH levels in children who are showing signs of pubertal alterations could suggest a syndrome known as "precocious pseudopuberty." Elevated levels of the hormones estrogen or testosterone cause the signs and symptoms.

LH and FSH levels can be normal or below what is expected for a child of this age range in delayed puberty.

This can be used to diagnose conditions related to the sex organs, early or late puberty, or a condition affecting the pituitary or hypothalamus. It is also used to predict ovulation, evaluate infertility and monitor during infertility treatment. Levels that are out of range can help, along with several other hormone test, to evaluate the cause of irregular menstrual cycles.

A Luteinizing Hormone, or LH, Test is a test that measures the level of the LH in the blood. It is used to predict ovulation, evaluate infertility and monitor during infertility treatment, or identify a pituitary disorder. It can also help along with several other hormone test to evaluate the cause of irregular menstrual cycles.

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

Average Processing Time: 1 to 2 days

When is a FSH and LH test ordered?

An FSH and LH test may be recommended for a woman if she is having trouble conceiving or has irregular or absent menstrual periods.

When a woman's menstrual cycle has ended or grown erratic, FSH and LH may be ordered to see if she has entered menopause.

When a man's spouse is unable to conceive, when he has a low sperm count, or when he has low muscle mass or diminished sex drive, for example, the test may be ordered.

When a health care provider detects a pituitary issue in a woman or a man, testing may be ordered. Because a pituitary problem can disrupt the production of a variety of hormones, other signs and symptoms may appear in addition to those described above. Fatigue, weakness, unexpected weight loss, and decreased appetite are just a few examples.

What does a FSH and LH blood test check for?

FSH and LH are hormones linked to production and the development of eggs and sperm in both men and women. FSH and LH is measured in the blood.

The pituitary gland produces FSH and LH. The hypothalamus in the brain, the pituitary gland, and hormones generated by the ovaries or testicles all work together to control FSH and LH production. The hypothalamus secretes gonadotropin-releasing hormone, which causes the pituitary to secrete FSH and luteinizing hormone.

During the follicular phase of the menstrual cycle, FSH and LH increases the growth and maturation of eggs in the ovaries in women. The menstrual cycle is divided into two phases: follicular and luteal, each lasting approximately 14 days. During this follicular phase, FSH triggers the follicle's synthesis of estradiol, and the two hormones collaborate to help the egg follicle develop further. A surge of FSH and luteinizing hormone occurs near the end of the follicular period. Shortly after this burst of hormones, the egg is released from the ovary. The hormones inhibin, estradiol, and progesterone all help the pituitary gland regulate the quantity of FSH released. FSH also improves the ovary's ability to respond to LH.

Ovarian function declines and eventually quits as a woman matures and approaches menopause. FSH and LH levels rise as a result of this.

FSH induces the development of mature sperm in men's testicles, as well as the production of androgen binding proteins. After adolescence, men's FSH levels remain rather steady.

FSH levels rise early after birth in infants and children, and then quickly fall to low levels by 6 months of age in boys and  around 1 and half years of age in girls. Before puberty and the development of secondary sexual characteristics, FSH levels begin to rise again.

The production of too much or too little FSH and LH can be caused by disorders affecting the brain, pituitary, ovaries, or testicles, resulting in infertility, irregular menstrual cycles, or early or delayed sexual development.

Lab tests often ordered with a FSH and LH test:

• Estrogen
• Estradiol
• Testosterone
• Progesterone
• Androstenedione
• Sperm Analysis
• Anti-Mullerian Hormone
• Prolactin
• Sex Hormone Binding Globulin

Conditions where a FSH and LH test is recommended:

• Infertility
• Menopause
• Pituitary Disorders
• Endocrine Syndromes
• PCOS

How does my health care provider use a FSH and LH test?

There are various applications for the follicle-stimulating hormone and luteinizing hormone test, which are hormones linked to reproduction and the development of eggs in women and sperm in men.

The test can be used with additional hormone assays including luteinizing hormone, testosterone, estradiol, and/or progesterone in both women and men to help:

• Find out what's causing infertility.
• Diagnose conditions involving ovarian or testicular dysfunction.
• Aid in the diagnosis of diseases of the pituitary or hypothalamus, which can impact FSH production.

FSH and LH levels are also relevant in women for:

• Menstrual irregularities are being investigated.
• Menopause start or confirmation prediction

FSH and LH levels in males are used to determine the cause of a low sperm count.

FSH and LH are used to identify delayed or early puberty in children. Puberty timing irregularities could indicate a more significant disease involving the hypothalamus, pituitary gland, ovaries, testicles, or other systems. LH and FSH levels can help distinguish between benign symptoms and real disease. Once it's been determined that the symptoms are due to an actual condition, more testing can be done to figure out what's causing them.

What do my FSH and LH test results mean?

FSH and LH test findings are frequently combined with those from other hormone testing estrogens, and/or testosterone.

A high or low FSH level as part of an infertility workup is not diagnostic, but it does provide some insight into the cause. A hormone imbalance, for example, can influence a woman's menstrual cycle and/or ovulation. To make a diagnosis, a doctor will take into account all of the information gathered during the examination.

Women's Health

• FSH and LH levels can assist distinguish between primary ovarian failure and secondary ovarian failure.
• Primary ovarian failure is associated with high levels of FSH and LH.
• Low FSH and LH levels are indicative of secondary ovarian failure caused by a pituitary or hypothalamic issue. Low FSH levels in the blood have been linked to an increased risk of ovarian cancer.

Men's Health

• Primary testicular failure causes high FSH levels. As shown below, this can be the result of developmental problems in testicular growth or testicular damage.
• Low levels are indicative of pituitary or hypothalamic dysfunction.

Children's Health

• Precocious puberty is defined by high levels of FSH and LH, as well as the development of secondary sexual traits at an extremely young age. This occurs far more frequently in girls than in boys. This abnormal development is usually caused by a problem with the central nervous system, which can have a variety of causes.
• Normal prepubescent LH and FSH levels in children who are showing signs of pubertal alterations could suggest a syndrome known as "precocious pseudopuberty."
• For children with delayed puberty, LH and FSH levels can be normal or below what is expected for children of their age.

Description: A growth hormone test is going to measure the amount of growth hormone in the body. It is used to determine if a person is deficient in growth hormone causing slowed growth. Less commonly, it can be used to determine if there is too much growth hormone causing gigantism or acromegaly.

Also Known As: GH Test, Growth Hormone GH, HGH Test, Human Growth Hormone (hGH), Somatotropin, Growth Hormone Stimulation Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: Patients should be fasting and have rested for at least 30 minutes prior to collection.

Average Processing Time: 3 to 4 days

When is a Growth Hormone test ordered?

When a kid exhibits the following signs and symptoms of growth hormone insufficiency, GH testing is recommended.

• A child's growth rate is slowed in early life
• Delay in puberty compared to other children of the same chronological age
• Bone growth is delayed 

Stimulation testing may be requested for an adult when there are symptoms of GHD and/or hypopituitarism, such as:

• Bone density has decreased
• Fatigue
• Deficiencies in lipids, such as excessive cholesterol
• Exercise tolerance is reduced

Other hormone testing, such as thyroid testing, is usually done first to rule out other causes of comparable symptoms. In both children and adults, GH deficiency is uncommon. If GH deficiency was detected in childhood or there is a history of hypothalamic or pituitary illness, it is conceivable in adults.

What does a Growth Hormone blood test check for?

Growth hormone is a hormone that is necessary for children's appropriate growth and development. From birth to adolescence, it promotes correct linear bone growth. Growth hormone regulates the rate at which the body produces energy from meals as well as lipids, proteins, and glucose in both children and adults. It also aids in the regulation of red blood cell formation and muscle mass.

The pituitary gland, a grape-sized gland behind the bridge of the nose at the base of the brain, produces growth hormone. It's released into the bloodstream in pulses throughout the day and night, with maxima occurring largely at night. As a result, a single measurement of GH in blood is difficult to interpret and is rarely relevant in clinical practice. If the sample is collected during a pulse, the value will be higher; if it is taken between pulses, the value will be lower. As a result, GH stimulation and suppression tests are frequently employed to detect GH anomalies.

GH insufficiency is a condition in which the body does not produce enough of

Insufficient GH production causes children to grow more slowly and to be smaller for their age. Some children are born with GH shortage, but others may develop a shortfall later in life as a result of a brain injury or tumor. These disorders can damage the pituitary gland, resulting in a reduction in pituitary function and decreased pituitary hormone production. The cause of a deficit is sometimes unknown.

Growth hormone is involved in the regulation of bone density, muscular mass, and glucose and lipid metabolism in adults. It can also have an impact on the heart and kidneys. Deficiencies might start in childhood or emerge later in life. Damage to the pituitary gland from a head injury, a brain tumor, surgery, or radiation treatment, for example, might create a deficit. Pituitary hormones may be reduced as a result of this. A GH deficit can cause a loss of bone density, muscle mass, and lipid levels to change. Adults with decreased bone density and/or muscle strength, as well as elevated lipids, are not routinely tested for GH insufficiency. These illnesses are caused by GH deficiency, which is a fairly unusual cause.

Excess GH

A GH-secreting pituitary tumor is the most common cause of excessive GH. Surgically removing the pituitary tumor that is producing the excess and/or treating it with medicines or radiation are frequently options. In most situations, GH and IGF-1 levels will revert to normal or near normal levels as a result of this.

In youngsters, too much GH can cause their long bones to continue to develop past puberty, culminating in gigantism, a rare disorder characterized by heights of 7 feet or more. Excess GH can cause face thickness, general weakness, delayed puberty, and headaches in those who have it.

Excess GH in adults can cause acromegaly, an uncommon disorder characterised by bone thickening rather than bone lengthening. Increased GH levels can lead to bigger hands and feet, expanded facial bones, carpal tunnel syndrome, and abnormally enlarged internal organs, despite symptoms like skin thickening, sweating, weariness, headaches, and joint discomfort being modest at first. Skin tags and intestinal polyps can also be caused by too much GH.

If neglected, acromegaly and gigantism can result in type 2 diabetes, a higher risk of high blood pressure, cardiovascular disease, arthritis, and, generally, a shorter lifespan.

Lab tests often ordered with a Growth Hormone test:

• IGF-1
• Growth Hormone Releasing Hormone
• TSH
• Free T3
• Free T4
• Cortisol
• Glucose
• Prolactin
• IGF BP-3

Conditions where a Growth Hormone test is recommended:

• Pituitary Disorders
• Thyroid Disorders
• Endocrine Syndromes

How does my health care provider use a Growth Hormone test?

Growth hormone testing is frequently done as a follow-up to other aberrant pituitary hormone test results in order to diagnose growth hormone insufficiency and evaluate pituitary gland function.

GH testing is also used to detect excess GH and to diagnose and track acromegaly and gigantism treatment.

Growth hormone is required for appropriate development and growth in children, as well as for the regulation of metabolism in both children and adults. GH is produced by the pituitary gland and released into the blood in pulses throughout the day.

Because growth hormone is released in pulses, a single blood level measurement is rarely useful in clinical practice. As a result, it's common to do tests to see if the pituitary is suppressing or stimulating growth hormone secretion.

GH stimulation tests are used to identify hypopituitarism and GH insufficiency. A sample of blood is collected after 10-12 hours of fasting for a stimulation test. The person is then given an intravenous solution of a chemical that generally stimulates the production of GH from the pituitary under under medical supervision. Blood is obtained at regular intervals and GH levels are measured to evaluate if the pituitary gland was stimulated to produce the desired levels of GH. The most common stimulant is arginine, but clonidine and glucagon are also utilized. Vigorous exercise, which generally induces an increase in GH, could be employed as a GH release stimulant.

GH suppression tests aid in the detection of GH excess. A blood sample is drawn after 10-12 hours of fasting for a suppression test. A standard glucose solution is then given to the person to drink. Blood samples are taken at regular intervals and examined for GH to evaluate if the glucose dose has suppressed the pituitary gland adequately.

Insulin-like growth factor-1 is produced in response to growth hormone. IGF-1 is a hormone that helps promote appropriate bone and tissue growth and development by mediating the effects of GH. Unlike GH, however, its blood level remains constant throughout the day. As a result, IGF-1 is a good indication of average GH levels, and the IGF-1 test is frequently used to diagnose GH shortage or excess.

A GH suppression test and IGF testing can also be used to track how well a GH-producing pituitary tumor is responding to treatment. If a tumor is found, the levels of GH and IGF-1 can be evaluated after it is removed to see if the tumor was completely eliminated. For years following, tests may be required at regular intervals to monitor GH production and detect tumor recurrence.

Prolactin, free T4, TSH, cortisol, FSH, LH, and testosterone are some of the other blood tests that can be used to assess pituitary gland function. These tests are routinely done before GH testing to ensure that they are normal and/or under control with medication before GH testing. Hypothyroidism, for example, must be treated before GH deficiency testing in children; otherwise, a falsely low GH result may be seen.

What do my growth hormone test results mean?

If the person has signs and symptoms of GHD and their GH levels are not significantly stimulated after a GH stimulation test, it is likely that they have a GH deficiency that the health practitioner can treat.

Thyroid issues can induce symptoms similar to GHD, therefore if the person's TSH and/or T4 levels are abnormal, it will likely be addressed first. Hypopituitarism and/or a general decline in pituitary function are also possible. GH deficiency tests should not be done until a person's thyroid function has been assessed. If a child has hypothyroidism, the condition should be addressed and the child's growth rate assessed before GH testing is considered.

If a person engages in rigorous exercise but does not see a rise in GH levels, they may have a GH deficiency. This discovery would need to be followed up with more testing.
