A cortisol levels blood test measures the amount of cortisol, a hormone your adrenal glands make, in your blood. It is ordered to check for conditions such as Addison's disease or Cushing's syndrome, and to evaluate symptoms like fatigue, weight changes, or high blood pressure.

What it measures

  • Cortisol — The main hormone being measured; levels change throughout the day.
  • Collection time — The time the blood was drawn, because cortisol peaks in the morning and drops later.
  • Reference range — The expected range for the time of day your sample was taken.

Who it is for

Doctors order this test when they suspect a cortisol imbalance, such as too much or too little cortisol, based on symptoms like unexplained weight gain or loss, fatigue, or darkening of the skin.

Preparation

Preparation depends on the time your test is scheduled. Often no fasting is required, but your doctor may ask you to avoid certain medications or to have the test at a specific time, such as early morning.

Results and what they mean

Results are reported as a number in micrograms per deciliter (mcg/dL) and are compared to a reference range for the time of day. Your clinician interprets the result along with your symptoms and other tests. This is general information, not medical advice; only your healthcare provider can diagnose or treat any condition.
