What does it measure?
DHEA sulfate is made mainly by the adrenal glands above the kidneys. It can be converted into other sex hormones. A blood measurement may help assess excess facial or body hair, acne with other hormone signs, early puberty, or a suspected adrenal disorder. [1]
Before the test
- Sample
- A blood sample from a vein.
- Preparation
- Usually no special preparation is needed for this test alone. Mention any DHEA supplement.
What can the result mean?
Higher levels can occur when the adrenal glands produce more androgens, including in some people with PCOS or certain adrenal conditions. Lower levels become more common with age and may also occur with illness or reduced adrenal function. A low result alone does not diagnose adrenal insufficiency. [1]
When is it useful, and how is it read?
The test is particularly useful when investigating excess androgen effects and a possible adrenal contribution. Its meaning changes when paired with testosterone and the speed or severity of symptoms. A low result alone does not diagnose adrenal insufficiency or establish a need for DHEA supplements. [1] [2]
What can affect it?
The expected range depends strongly on age and sex. DHEA supplements directly affect the result, and steroid medicines can alter adrenal hormone production. Your symptoms and other hormone measurements help distinguish a meaningful change from expected variation. [1]
DHEA-S changes substantially with age
DHEA-S usually falls as people get older. A value that would be low for a young adult may fit an older person’s expected pattern, so age-specific interpretation matters more than comparing with someone else’s result. [1]
Questions you might have
Should I compare my DHEA-S with a younger person’s?
No. Expected levels change with age and sex. Use the laboratory interval appropriate to you. [1]
Does DHEA-S mainly reflect ovarian hormones?
No. Most DHEA-S comes from the adrenal glands. It adds information about adrenal androgen production. [1]
What comes next?
Review an unexpected result with your clinician rather than using DHEA as an anti-aging supplement. Further testing should follow the clinical question, sometimes including testosterone or other adrenal hormones. Rapidly developing androgen-related changes deserve timely assessment, even if you otherwise feel well. [1]
Is this level unusual for my age, and what specific question would another test answer?
The reference interval and units on your report are part of understanding your result. Understand units, reference intervals, and treatment targets.
