This test measures the level of dihydrotestosterone (DHT) in the blood, which is crucial for diagnosing conditions like 5-alpha-reductase deficiency that affects male sexual development. It's also used to monitor the effectiveness of treatments that impact androgen levels. DHT is a key androgen involved in the development of male external genitalia, prostate growth, and skin health. It's mainly produced from testosterone through the action of 5-alpha-reductase in tissues.
