DHEA
Dehydroepiandrosterone (DHEA) is an androgen synthesized and secreted primarily by the adrenal cortex. It has a short half-life and its concentration in the blood is 300-fold lower than that of DHEA sulfate. There is a circadian rhythm of secretion with highest concentrations in the morning. DHEA is a sensitive indicator of adrenal androgenic secretion and its determination can be used for the diagnosis and differential diagnosis of hyperandrogenism and premature adrenarche and as an aid in the diagnosis of congenital adrenal hyperplasia.
