A pregnenolone test measures the level of pregnenolone in your blood. Pregnenolone is a hormone made mainly by the adrenal glands and is a building block for other hormones like cortisol and sex hormones. This test is usually ordered when a doctor suspects a hormone imbalance or wants to check how your adrenal glands are working.

What it measures

  • Pregnenolone — The main hormone measured, often reported in nanograms per deciliter (ng/dL).
  • DHEA — Another adrenal hormone that may be checked alongside pregnenolone.
  • Cortisol — A stress hormone that can help show how the adrenal glands are functioning.
  • Progesterone — A hormone made from pregnenolone, useful for understanding hormone pathways.

Who it is for

Doctors may order this test for people with symptoms of hormone imbalance, such as unusual fatigue, mood changes, or irregular periods. It is also used in some evaluations of adrenal gland disorders.

Preparation

No special preparation is usually needed. Your doctor may ask you to have the blood drawn at a certain time of day, often in the morning, because hormone levels can change throughout the day.

Results and what they mean

Results are reported as a number for each hormone measured, along with a reference range from the lab. Your doctor will interpret these numbers based on your symptoms, age, and other tests. This information is general and not a substitute for medical advice.
