DHEA-S is an androgenic steroid secreted by the adrenal cortex and is the major androgen precursor in females.
Methodology
Immunoassay-Competitive principle
- Elevated DHEA-S values aid in the diagnosis of hirsutism and virilism
- Elevated DHEA-S levels may be useful for the diagnosis of:1-4
- All forms of excess androgen
- Hyperprolactinemia
- Polycystic ovarian syndrome
- Exclusion of an androgen producing tumor of the adrenal cortex
- Genetic enzyme defects of the adrenal cortex (adrenogenital syndrome)
- Hyperplasia of the adrenal cortex as well as androgen producing tumors
- High doses of biotin (> 5 mg/day) may interfere with assay results. Patient assumed to be refraining from biotin supplementation for at least 3 days prior to blood draw.
