ANDROSTENEDIONE (A4)

Androstenedione is a steroid hormone produced by the adrenal glands and gonads, serving as a precursor to testosterone and estrogen. The androstenedione test measures the level of this hormone in the blood and is used to assess adrenal and gonadal function. Elevated levels of androstenedione can indicate conditions such as polycystic ovary syndrome (PCOS), adrenal hyperplasia, or adrenal tumors. In men, abnormal levels may be associated with testicular dysfunction. This test is valuable for diagnosing hormonal imbalances, guiding fertility evaluations, and monitoring the effectiveness of treatments for disorders affecting adrenal and gonadal function.
