What this test is
Cortisol is a hormone produced by the adrenal glands that helps regulate metabolism, immune response, and the body's reaction to stress. This blood test quantifies the total amount of cortisol circulating in the blood at the time of collection. It is typically used alongside other tests to assess adrenal function.
What it measures
- Cortisol — reflects the amount of this hormone in the blood at the time of collection
What the test involves
The test requires a standard blood draw, usually from a vein in your arm, performed at a collection facility. The sample is then sent to a laboratory for analysis, and results are typically available within a few business days.
Why it is often ordered
A clinician may order a cortisol blood test when symptoms suggest an adrenal gland disorder, such as fatigue, weight changes, or blood pressure abnormalities. It can also be used to monitor conditions or treatments that affect cortisol production.
Preparation
Preparation instructions can vary depending on the time of collection and the reason for testing, so follow the specific directions provided by the collection laboratory. This may include timing the draw to a certain hour or avoiding certain medications beforehand.
How results are reported
Results are reported as a numerical value, often in micrograms per deciliter, and may include a reference range for context. Reference ranges differ between laboratories, so your result should always be interpreted using the range provided by the testing lab.
