What is

DHEA (Dehydroepiandrosterone) is an androgen hormone produced from cholesterol that your body converts into other hormones, including testosterone and oestrogen.

Why measure

Most of the DHEA in your body exists in your blood in the sulphated form, DHEAS, which we measure in this test. Measuring DHEAS can help to investigate adrenal insufficiency and tell you whether your levels are normal for your age. DHEAS can also help to identify polycystic ovaries as levels are likely to be elevated.

What could low
DHEA levels indicate?

DHEA levels in the body naturally decline as you get older. It affects many areas of health and well-being, and levels naturally decline as you get older. Research is continuing into whether DHEA can boost the immune system or help manage diabetes and lupus symptoms. Research is continuing into whether lower levels of DHEA can explain certain age-related ailments such as heart disease in older men, whether it has the ability to boost the immune system, and whether it can help in managing diabetes and easing lupus symptoms. There may also be a role for it in improving the chances of successful IVF.
