Good reasons to test
  • Unexplained fatigue, reduced vitality, or mood changes
  • Investigating androgen excess (acne, hirsutism, irregular periods)
  • Adrenal function or stress response assessment

No fasting required. Morning preferred — adrenal hormone levels are typically higher in the morning Results arrive in 3 to 5 business days, explained in plain language in your dashboard. Most results sit within the usual range - that is still useful, and anything unexpected supports a conversation with your healthcare practitioner.

Why this test

DHEA-S is one of the most abundant hormones in the body — and one of the first to decline with age.

DHEA sulphate (DHEA-S) is produced primarily by the adrenal glands and serves as a precursor to both testosterone and oestrogen. Levels peak in the mid-twenties and decline steadily thereafter. Very low levels may be associated with adrenal insufficiency; very high levels may suggest adrenal tumour or congenital adrenal hyperplasia. This test is often used in the context of fatigue, androgen excess, or adrenal function assessment.

Understanding your results

Within reference range

Your DHEA-S is within the expected range for your demographic (see full report for age/sex-specific ranges)

Low-normal

Within range — interpretation is age and sex-dependent

Below reference range

May warrant investigation of adrenal function — discuss with your healthcare practitioner

Above reference range

Elevated DHEA-S may warrant further investigation — discuss with your healthcare practitioner

Reference ranges vary by laboratory and personal context. Your result is shown against the lab's range in your dashboard, alongside what it means.

DHEA-S is your body's own production of DHEA in its sulphated (storage) form. DHEA supplements are available in some countries, but their use should be discussed with a healthcare practitioner — this test measures your natural levels, not supplement levels.

The adrenal glands naturally produce less DHEA-S over time, a process sometimes called adrenopause. This is a normal part of ageing, though the magnitude of decline varies between individuals.

No fasting is required. Morning testing is preferred as adrenal hormones are typically higher earlier in the day.

Once or twice a year if monitoring adrenal or hormonal function. Otherwise, a baseline with a repeat if symptoms change — DHEA-S declines naturally with age, so comparing results over time is meaningful.
