Dehydroepiandrosterone sulphate (DHEAS) is the sulphated ester of the 19-carbon androgen DHEA, produced by the adrenal gland. DHEAS is the most abundant circulating androgen and shows no diurnal rhythm. DHEAS acts as a precursor to other androgens, such as androstenedione and testosterone.
Measurement of DHEAS may be of benefit for the investigation of excess androgen. DHEAS is relatively specific for the adrenal glands, whereas other androgens, such as testosterone and androstenedione are also produced by the gonads.
