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.

Before you go

  • Whether any medications or supplements should be paused before the test
  • The preferred time of day for your blood draw
  • Whether fasting or other dietary restrictions are needed
