DHEA Sulfate (DHEA-S) (1134)

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.
