Hormonal evaluation for acne will usually include tests of serum DHEAS, free testosterone and total testosterone levels.
Elevation of serum DHEAS levels indicates an adrenal source of androgen production. Modest elevations of DHEAS are most commonly associated with late-onset congenital adrenal hyperplasia that may not have been previously diagnosed.
Elevation of testosterone is associated with excess androgens produced by the ovaries. Modest elevation of testosterone is most commonly associated with Polycystic Ovary Syndrome (PCOS).
All these results require further evaluation by your physician.
Important: Hormonal blood tests should be drawn just prior to, or during menses. As oral contraceptives at the time of testing can mask an underlying endocrine abnormality, testing should be performed at least 4 to 6 weeks after you stop the oral contraceptive.
