DHEA-Sulfate is a hormone produced by the adrenal glands that serves as a precursor to both testosterone and estrogen. It's the most abundant steroid hormone in the body and declines steadily with age. Testing DHEA-S can help evaluate adrenal function, PCOS in women, and hormone imbalances. It's also used to investigate symptoms like fatigue, low libido, and unexplained hair loss.
DHEA-Sulfate — the most abundant adrenal androgen, peaking at age 25 then declining ~10% per decade. Used to evaluate adrenal function, premature pubarche, hirsutism in women, and androgenic alopecia.
Women with hirsutism, hair thinning, or suspected PCOS; men investigating low T (DHEA precursor); anyone evaluating adrenal vs ovarian/testicular sources of androgen excess; anti-aging/hormone optimization users.

What can throw off this result
Physician-reviewed “Before your test” pages — what each factor does, for how long, and what to do about it.
A DHEA-Sulfate test costs $32.99 at TestWell — $38.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. Ordered directly from the labs' own consumer sites, the same test lists at $69.00 at Labcorp OnDemand (list prices checked Sep 12, 2026). Hospital outpatient labs typically bill around $130.00 self-pay for the same test, and often more. With insurance, what you pay depends on your deductible and your plan's negotiated rate; TestWell's price is fixed before the draw and is HSA/FSA-eligible.

DHEA-Sulfate (DHEA-S) is the storage form, stable across the day. DHEA itself has a short half-life and fluctuates. DHEA-S is the standard clinical test for adrenal androgen status.
TestWell charges $32.99 — vs $49 at Quest Direct and $80-$180 at hospital labs.
Age-adjusted ranges (women): 20-30y 65-380 mcg/dL, 30-40y 45-270, 40-50y 32-240, 50-60y 26-200, 60-70y 13-130. Men: 20-30y 280-640, declining to 24-244 by 70+.
Yes — high DHEA-S with normal testosterone points to adrenal source; high DHEA-S with high T points to PCOS or rare androgen-secreting tumor. Order Testosterone Total alongside.

Oral contraceptives and estrogen can change a DHEA-Sulfate test result without anything being wrong. Oral contraceptives and estrogen can lower DHEA-Sulfate — A low free T on the pill does not mean androgen deficiency; if testing for PCOS, results are muted. Each factor is covered on our physician-reviewed "Before your test" pages; when one applies, the fix is usually to remove it and retest.
