Quick answer

A DHEA sulfate test is a blood test that measures dehydroepiandrosterone sulfate, an androgen produced mainly by the adrenal glands. It is often ordered when a provider wants to assess adrenal androgen production, investigate signs such as excess hair growth or acne in women, or evaluate symptoms that may relate to hormonal imbalance. The result is interpreted with age and sex in mind.

What this test measures

DHEA sulfate is the sulfated form of DHEA and is one of the most abundant steroid hormones in circulation. Because it has a longer half-life than unconjugated DHEA, it is often preferred for assessing adrenal androgen output. Levels are naturally highest in early adulthood and decline with age, so reference ranges are stratified accordingly.

The test uses a serum sample collected from a vein, and no special preparation is usually required, though some laboratories may request a morning draw. Results are reported as a concentration with an age- and sex-specific reference range from the performing laboratory. Serial measurements can help a provider track changes over time.

People may order this test when evaluating adrenal function, unexplained androgen symptoms, or a possible adrenal condition. It is also used in some fertility and hormone evaluations, and in monitoring contexts determined by a provider. It is not a standalone diagnostic tool, and results should be interpreted alongside the broader clinical picture.

Frequently Asked Questions

What is DHEA sulfate?

It is the sulfated form of DHEA, an adrenal hormone that serves as a building block for testosterone and estrogen production in the body.

Why are age-based reference ranges used?

DHEA sulfate levels naturally peak in early adulthood and decline with age, so laboratories compare results with ranges specific to age and sex.

Can this test diagnose an adrenal disorder?

No. It provides one measurement that a qualified healthcare provider interprets with symptoms, history, and other testing before reaching any conclusion.

Do I need to fast?

Fasting is not usually required, but follow the instructions supplied with your order in case the laboratory requests it.

Can DHEA sulfate be monitored over time?

Yes. Repeat measurements can help a provider observe trends, particularly when monitoring a known condition or the effect of a treatment plan.
