Dihydrotestosterone

What this laboratory test evaluates

DetailsDihydrotestosterone (DHT) Test – This test measures the level of DHT, a powerful androgen made from testosterone through the action of 5-Alpha-Reductase. Understanding DHT levels is crucial for diagnosing conditions related to hormone balance, such as 5-Alpha-Reductase deficiency, which can lead to underdeveloped male characteristics (appearing as phenotypic females). The test helps by comparing the ratio of testosterone to DHT.

What patients is this test right for?This test is particularly important for individuals showing signs of hormonal imbalance or those with conditions affecting their sexual development.

What type of sample is required for this test?1 mL of serum is needed, collected in a red-top tube (no gel).
