Test Overview
Test Methodology

Liquid Chromatography - Tandem Mass Spectrometry (LC-MS/MS)

Test Usage

Evaluation of androgen disorders, characterized frequently by an elevated level of androstenedione and/or testosterone, which may suggest excess androgen production by the ovary.

Reference Range *

0 - 17 yrs: no reference range; adult males (18 - 150 yrs): 40.0 - 150.0 ng/dL; adult females (18 - 150 yrs): 30.0 - 200.0 ng/dL

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Test Limitations

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.
