Use:The primary clinical use of AD levels is evaluation of hirsutism (abnormal hair growth) in which it is elevated in 60% of the cases. AD levels may also be elevated polycystic ovarian disease, congenital adrenal hyperplasia, and tumors of the adrenals or gonads. AD is not helpful in separating adrenal from gonadal causes of excess androgen secretion. Serum AD concentrations exhibit diurnal variation. Highest values occur at about 7:00 a.m., with lowest levels around 4:00 p.m., a magnitude of change of at least two. Levels also vary with the phase of the menstrual cycle. As the follicle matures and ovulation occurs, there is a twofold increase in AD levels that is maintained throughout the luteal phase.
