About this test
DHEA-S is an adrenal hormone and the body's largest reservoir for making testosterone and estrogen. It is steady through the day, so it does not need timing, and it declines slowly with age.
It is checked in PCOS and unwanted hair growth workups to see whether the adrenal glands are contributing, and in adrenal questions more broadly. A high value is read with testosterone and cortisol; supplements containing DHEA raise it.
Reading your result
DHEA-S declines gradually with age and is raised by DHEA supplements and adrenal overactivity. It is steady across the day and the cycle, so timing is not a factor.
Steroid medicines and some hormonal treatments lower it. Because it is stable across the day and the cycle, a single value is usually enough, and it is read with testosterone and cortisol when the question is adrenal.
