This blood test is often done for women who seem to have too many male hormones. It can also be done when a woman has a low sex drive and when a boy starts puberty too early. DHEA stands for dehydroepiandrosterone. This is a hormone found in the adrenal glands, above the kidneys. DHEA helps to make other hormones, like testosterone in men and estrogen in women. Your natural DHEA levels are highest when you're a young adult. They get lower as you age. In your adrenal glands and liver, DHEA changes to DHEA-S (DHEA-sulfate).
