DHEA-S (dehydroepiandrosterone sulfate)

Adrenal · specimen: blood

Indicated in specific situations

Also called: DHEAS, DHEA sulfate, DHEA-SO4, dehydroepiandrosterone sulphate

Chart note

Pick Ordered or Not ordered to see the note.

Indicated when

  • Working up hyperandrogenism or hirsutism in women: DHEA-S is part of the recommended androgen testing when a patient has an abnormal hirsutism score [1]
  • Suspected androgen-secreting adrenal tumour, especially with rapid-onset or severe virilization [1]
  • Part of the work-up for PCOS-pattern hyperandrogenism, to help localize an androgen source to the adrenal gland [1]

Not indicated when

  • Routine use of DHEA-S to diagnose 'androgen deficiency' in women, or to justify DHEA supplementation for low energy, low libido, or general well-being: no well-defined deficiency syndrome exists and levels do not correlate reliably with symptoms [2]
  • Screening asymptomatic patients for 'adrenal fatigue' [3, 4]

Why not

DHEA-S has wide population variability and no validated symptom-correlated reference range for 'low energy' or 'adrenal fatigue,' so ordering and treating to a number outside a directed hyperandrogenism or tumour work-up risks unnecessary DHEA supplementation, which the Endocrine Society specifically recommends against for routine use in women given limited effectiveness and safety data [2].

Better first step

If the concern is hirsutism or possible hyperandrogenism, use a validated hirsutism score and test DHEA-S alongside total or free testosterone as part of that specific work-up [1]; if the concern is general fatigue or low libido, look for other causes rather than treating a DHEA-S number.

Typical ND rationale

An ND may order DHEA-S as one of the adrenal hormones to check in a patient with fatigue or low resilience to stress, reasoning that DHEA, made by the adrenal glands, contributes to energy and hormone balance, and that a low level would explain symptoms and justify DHEA supplementation.

Where the ND is right

DHEA-S is genuinely useful, and the instinct to think of the adrenal gland as an androgen source is correct: in a woman with hirsutism, irregular cycles, or other signs of hyperandrogenism, DHEA-S is a recommended part of the diagnostic work-up [1].

Ontario coverage & CONO orderability

OHIP status
insured
Listed by name in the 2026 Schedule of Benefits for Laboratory Services (L347 Dehydroepiandrosterone sulphate (DHEAS)); insured when ordered by a physician, midwife, or NP who has clinically assessed the patient. The Schedule entry carries no specimen qualifier, so this applies to the standard serum/blood assay; saliva and urine DHEA-S variants are unverified (see cono_orderable). ND-ordered testing is patient-paid regardless [7, 8].
CONO orderable
Yes — CONO list #53, #151, #174
CONO 53 (blood), 151 (urine), 174 (saliva) — all 'Dehydroepiandrosterone sulphate (DHEAS).' Only the blood assay (CONO 53) is confidently matched to the OHIP-listed L347; the saliva and urine variants' coverage is unverified because the Schedule entry does not specify specimen.

Linked conditions

Counselling script

“DHEA-S is a useful test when there are signs of too much male-type hormone, like new facial hair, acne or irregular periods, because it helps show whether the adrenal gland is the source. It isn't a good test for tiredness or low libido, since healthy people's levels vary widely and a low number doesn't mean you need DHEA supplements. I don't see those signs today, so I'd focus on other causes of how you're feeling.”

Revisit if

  • New excess hair growth (hirsutism)
  • New or worsening acne with irregular periods
  • Rapid-onset virilization

Evidence notes

The OHIP listing (L347) has no specimen qualifier in the Schedule text; this record treats it as covering the standard serum assay only, consistent with how the CONO list separately itemizes saliva (174) and urine (151) as distinct specimens. No Canadian-specific guideline on DHEA-S testing was located within budget; a PCOS-specific international guideline was not fetched this session (deprioritized under the token budget in favour of the more directly on-point hirsutism guideline) and could sharpen the PCOS linkage on clinical review.
