Compare - Metabolism Test (EW)

The following is a list of what is included in the item above. Click the test(s) below to view what biomarkers are measured along with an explanation of what the biomarker is measuring.

Also known as: Cortisol AM

Cortisol, A.M.

A cortisol level is a blood test that measures the amount of cortisol, a steroid hormone produced by the adrenal gland. The test is done to check for increased or decreased cortisol production. Cortisol is a steroid hormone released from the adrenal gland in response to ACTH, a hormone from the pituitary gland in the brain. Cortisol affects many different body systems. It plays a role in: bone, circulatory system, immune system. metabolism of fats, carbohydrates, and protein. ervous system and stress responses.

Also known as: Testosterone Free Dialysis and Total LCMSMS

Free Testosterone

In many cases, measurement of total testosterone provides the doctor with adequate information. However, in certain cases, for example when the level of SHBG is abnormal, a test for free or bioavailable testosterone may be performed as it may more accurately reflect the presence of a medical condition.


A testosterone test measures the amount of the male hormone, testosterone, in the blood. Both men and women produce this hormone. In males, the testicles produce most of the testosterone in the body. Levels are most often checked to evaluate signs of low testosterone: In boys -- early or late puberty and in men -- impotence, low level of sexual interest, infertility, thinning of the bones In females, the ovaries produce most of the testosterone and levels are most often checked to evaluate signs of higher testosterone levels, such as: decreased breast size, excess hair growth, increased size of the clitoris. irregular or absent menstrual periods and male-pattern baldness or hair thinning.

Also known as: Thyroid Stimulating Hormone, Thyroid Stimulating Hormone (TSH), Thyrotropin


A TSH test is a lab test that measures the amount of thyroid stimulating hormone (TSH) in your blood. TSH is produced by the pituitary gland. It tells the thyroid gland to make and release thyroid hormones into the blood.


*Important Information on Lab Test Processing Times: Ulta Lab Tests is committed to informing you about the processing times for your lab tests processed through Quest Diagnostics. Please note that the estimated processing time for each test, indicated in business days, is based on data from the past 30 days across the 13 Quest Diagnostics laboratories for each test. These estimates are intended to serve as a guide and are not guarantees. Factors such as laboratory workload, weather conditions, holidays, and the need for additional testing or maintenance can influence actual processing times. We aim to offer estimates to help you plan accordingly. Please understand that these times may vary, and processing times are not guaranteed.

Brief Description: The Metabolism Lab Test is a comprehensive panel that includes the measurement of several key markers related to metabolic health. This panel assesses various aspects of the endocrine system, including cortisol levels, thyroid function, and testosterone levels. These markers play crucial roles in metabolism, energy regulation, and overall well-being.

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: Specimen must be collected before 9am

Specific to Cortisol: Assay is not recommended when patient is receiving prednisone/prednisolone therapy due to cross reactivity with the antibody used in this assay Specimen must be collected before 9 am.

Specific to TSH: Specimen collection after fluorescein dye angiography should be delayed for at least 3 days. For patients on hemodialysis, specimen collection should be delayed for 2 weeks.

According to the assay manufacturer Siemens: "Samples containing fluorescein can produce falsely depressed values when tested with the Advia Centaur TSH3 Ultra assay."

When and Why the Metabolism Lab Test May Be Ordered

Timing of the Test: The Metabolism Lab Test may be ordered when healthcare providers want to evaluate a patient's metabolic status or investigate specific symptoms related to hormonal imbalances. It is typically performed in the morning to capture cortisol levels at their peak.

Reasons for Ordering the Test:

  1. Assessment of Hormonal Balance: Healthcare providers may order this test when patients present with symptoms or conditions suggestive of hormonal imbalances. These symptoms may include fatigue, weight changes, mood disturbances, and menstrual irregularities.

  2. Evaluation of Adrenal Function: Cortisol, measured in the morning (Cortisol AM), is a key hormone produced by the adrenal glands. Abnormal cortisol levels can indicate adrenal dysfunction, such as Cushing's syndrome or Addison's disease.

  3. Thyroid Function Evaluation: The test includes Thyroid Stimulating Hormone (TSH) measurement, which helps assess thyroid function. TSH levels are often used to diagnose thyroid disorders, such as hypothyroidism or hyperthyroidism.

  4. Assessment of Testosterone Levels: Testosterone levels, both total and free, are important for male health. Abnormal testosterone levels can impact energy, muscle mass, mood, and sexual function. The test can be ordered to investigate testosterone-related symptoms.

  5. Monitoring Hormone Replacement Therapy: For individuals receiving hormone replacement therapy (e.g., thyroid medication or testosterone replacement), this panel can help healthcare providers adjust the treatment and ensure it remains within therapeutic ranges.

What the Metabolism Lab Test Checks For

The Metabolism Lab Test assesses the following markers:

  1. Cortisol AM (Morning Cortisol): Cortisol is a hormone that plays a crucial role in regulating metabolism, managing stress, and maintaining overall health. Abnormal cortisol levels can indicate adrenal gland dysfunction or stress-related conditions.

  2. Testosterone Free: Free testosterone represents the unbound, bioavailable form of testosterone in the bloodstream. It is essential for various male functions, including muscle development, mood, and sexual health.

  3. Testosterone Total: Total testosterone measures the overall amount of testosterone in the blood, including both bound and unbound forms. It is an important marker for assessing male health and hormonal balance.

  4. Thyroid Stimulating Hormone (TSH): TSH is produced by the pituitary gland and regulates thyroid hormone production. Abnormal TSH levels can indicate thyroid disorders, such as hypothyroidism or hyperthyroidism.

How Health Care Providers Use the Results of the Metabolism Lab Test

Healthcare providers use the results of the Metabolism Lab Test to:

  1. Diagnose Hormonal Imbalances: Abnormalities in cortisol, testosterone, or TSH levels can help diagnose conditions related to adrenal gland dysfunction, low testosterone, or thyroid disorders.

  2. Guide Treatment: The test results assist healthcare providers in developing treatment plans tailored to the patient's specific hormonal imbalances. This may include hormone replacement therapy, lifestyle modifications, or dietary recommendations.

  3. Monitor Hormone Therapy: For individuals undergoing hormone replacement therapy, regular monitoring of hormone levels ensures that therapy remains effective and within therapeutic ranges.

  4. Assess Overall Metabolic Health: This panel provides valuable insights into the patient's metabolic health and can help identify factors contributing to symptoms like fatigue, mood changes, or weight fluctuations.

  5. Screen for Hormonal Disorders: The test can be used as a screening tool to detect potential hormonal disorders early, allowing for prompt intervention and management.

In summary, the Metabolism Lab Test is a comprehensive assessment of hormonal markers related to metabolism and overall health. It aids in diagnosing hormonal imbalances and guiding appropriate treatment strategies to optimize metabolic function and well-being.

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