- Dehydroepiandrosterone (DHEA)
- Dehydroepiandrosterone Sulfate (DHEA S)
AD, DHEA, and DHEA S are blood tests used to measure precursors of the hormones testosterone and estrone that are released by the testicles and adrenal glands. These hormones regulate masculine characteristics in both males and females. Certain diseases can affect the amount of these hormones within the body. Abnormal levels, especially during puberty, can lead to changes in hair growth and male body characteristics in females, and early or delayed puberty in males. High levels are the result of adrenal or ovarian cancer, Cushing's syndrome, or Stein-Leventhal syndrome. Gonad failure, or adrenal insufficiency causes low levels of these hormones.
