About the test

This test quantifies the serum levels of total and free DHT using liquid chromatography-tandem mass spectrometry (LC/MS) and dialysis. It aids in diagnosing and managing conditions related to altered androgen metabolism. It is particularly useful in evaluating conditions such as 5-alpha-reductase deficiency, a genetic disorder that can impact male sexual development.
