Androstenedione, Urine Creatinine Ratio Unit Converter

Androstenedione is a steroid hormone that acts as a precursor to the major sex hormones testosterone and estrogen. On its own, it has relatively weak androgenic effects. Its importance lies in the body's ability to convert it into more potent hormones in various tissues.

This test measures androstenedione levels in urine, normalized to creatinine to account for differences in urine concentration. Creatinine correction provides a more consistent measurement than raw urine values, as it adjusts for hydration status.

Urinary androstenedione correlates strongly with serum androstenedione, total testosterone, and free testosterone levels, making it a useful marker for assessing overall androgen status.

Androstenedione is produced by the adrenal glands (in both sexes), the ovaries (in women), and the testes (in men). The pituitary hormones ACTH and LH regulate its release from the adrenal glands and gonads, respectively.
