A DHEA blood test measures the levels of Dehydroepiandrosterone in the blood. DHEA is a parent, or master, steroid hormone that the body changes into the androstenedione hormone (Dehydroepiandrosterone Sulfate or DHEA-S). The body then changes androstenedione into the major male and female hormones. A DHEA blood test is often combined with a DHEA-S blood test, which both can additionally indicate how well adrenal glands are functioning.

Dehydroepiandrosterone is a steroid hormone produced by both the testis and adrenal glands (cortex). DHEA levels increase before the onset of adrenarche (puberty) and decrease significantly with as people age. DHEA and DHEA-S are the major precursors of 17-ketosteroids. This blood test can also be used to evaluate adrenal carcinomas, which often secrete large volumes of DHEA.
