Cortisol AM & PM Test in Kansas

The Cortisol AM & PM Test measures cortisol levels in your blood at two different times of day. Cortisol is a hormone made by the adrenal glands that helps regulate stress response, blood sugar, and metabolism. Doctors order this test to check for conditions like Cushing's syndrome or Addison's disease, which affect cortisol production.

What it measures

Cortisol (morning) — The level of cortisol in your blood drawn in the morning, when it is usually highest.
Cortisol (evening) — The level of cortisol in your blood drawn in the evening, when it is usually lower.
Diurnal variation — The difference between morning and evening cortisol levels, which helps show if your daily rhythm is normal.

Who it is for

This test is typically ordered by an endocrinologist or primary care doctor when you have symptoms of a hormone imbalance, such as unexplained weight gain, fatigue, or high blood pressure.

Preparation

No special preparation is usually needed, but you may be asked to avoid eating, drinking caffeine, or exercising for a few hours before each blood draw. Your doctor will give you specific timing instructions for the morning and evening samples.

Results and what they mean

Results are reported as two cortisol values with reference ranges for the time of day. Your clinician will interpret these numbers along with your symptoms and other tests. This information is not medical advice; only a healthcare professional can diagnose or treat any condition.
