Useful For

Measurement of circulating levels of Dehydroepiandrosterone sulfate (DHEAS), an adrenal steroid, is important in investigations of abnormal hair growth (hirsutism) and balding (alopecia) in women.  It is also of value in the assessment of adrenarche and delayed puberty.  DHEAS in circulation originates almost entirely from the adrenals, though in men some may also derive from the testes.  Although DHEAS is weakly androgenic, it can metabolize to more potent androgens like androstenedione and testosterone, and thus be an indirect cause of hirsutism or virilization.
