Liquid Chromatography - Tandem Mass Spectrometry (LC-MS/MS)
Evaluation of androgen disorders, characterized frequently by an elevated level of androstenedione and/or testosterone, which may suggest excess androgen production by the ovary.
0 - 17 yrs: no reference range; adult males (18 - 150 yrs): 0.4 - 1.5 ng/mL; adult females (18 - 150 yrs): 0.3 - 2.0 ng/mL
Androstenedione is an adrenal androgen. Therefore, physiological states that can result in partial or complete adrenal or gonadal failure may cause low androstenedione levels. Supplements containing androstenedione and dehydroepiandrosterone sulfate can also cause elevated serum androstenedione levels.
