Dehydroepiandrosterone (DHEA) Blood Test
This page explains the dehydroepiandrosterone (dhea) blood test, what it measures, and how to arrange it. A DHEA blood test measures the amount of dehydroepiandrosterone (DHEA) and often its sulfate form (DHEA-S) in your blood. DHEA is a hormone made mainly by the adrenal glands that the body uses to make other hormones, including testosterone and estrogen. It is usually ordered when a clinician is checking adrenal function or looking into symptoms that may relate to hormone imbalance.

A DHEA blood test measures the amount of dehydroepiandrosterone (DHEA) and often its sulfate form (DHEA-S) in your blood. DHEA is a hormone made mainly by the adrenal glands that the body uses to make other hormones, including testosterone and estrogen. It is usually ordered when a clinician is checking adrenal function or looking into symptoms that may relate to hormone imbalance.
What it measures
- DHEA — The active form of the hormone, which rises and falls throughout the day.
- DHEA-S — A more stable storage form that changes slowly, so it is often preferred for testing.
- Total DHEA or DHEA-S level — Reported as a number, usually in micrograms per deciliter (mcg/dL).
- Reference range — The expected range for your age and sex, since DHEA naturally declines with age.
Who it is for
A clinician such as a primary care doctor, endocrinologist, or gynecologist may order this test. It is often used when symptoms suggest low or high adrenal hormone levels, or to monitor a known adrenal condition.
Preparation
No fasting is usually required. Tell your clinician about any hormone supplements, since DHEA products can affect the result; timing may matter because DHEA levels vary during the day.
Results and what they mean
Results are reported as a number compared with a reference range for your age and sex. A clinician interprets the result along with your symptoms, other hormone tests, and medical history. This is general information only and is not medical advice; discuss your results with a qualified clinician.

Frequently asked questions
Do I need to fast before this test?
Fasting is typically not required, but follow any instructions your clinician gives you.
Can supplements affect my result?
Yes. DHEA, testosterone, and some other hormone products can change your level, so tell your clinician what you take.
Why is DHEA-S sometimes tested instead of DHEA?
DHEA-S stays steadier through the day, which can make it easier to interpret than the rapidly changing DHEA level.
How soon will I get results?
Turnaround is commonly 1 to 3 business days, though it can vary by lab.
