Additional Codes

Mayo Test ID
DHEA_

Reporting Name

Dehydroepiandrosterone, S

Useful For

Diagnosing and differential diagnosis of hyperandrogenism (in conjunction with measurements of other sex steroids)

 

An initial screen in adults might include dehydroepiandrosterone (DHEA)/dehydroepiandrosterone sulfate (DHEAS) and bioavailable testosterone measurement. Depending on results, this may be supplemented with measurements of sex hormone-binding globulin and occasionally other androgenic steroids (eg, 17-hydroxyprogesterone).

 

An adjunct in the diagnosis of congenital adrenal hyperplasia (CAH); DHEA/DHEAS measurements play a secondary role to the measurements of cortisol/cortisone, 17 alpha-hydroxyprogesterone, and androstenedione.
