The purpose of the test is to:
The Dihydrotestosterone (DHT) test measures the level of dihydrotestosterone in the blood. DHT is a potent androgen hormone produced when testosterone is converted by the enzyme 5-alpha-reductase. It plays an important role in male sexual development, prostate function, and the development of male-pattern hair growth.
DHT testing may be considered when a healthcare provider needs to evaluate androgen-related conditions, abnormal sexual development, or suspected problems with testosterone metabolism. It may also be used in selected cases involving hair loss, hirsutism, or disorders affecting androgen activity.
DHT results are generally interpreted together with other hormone tests and the individual's symptoms and medical history.
1. What is DHT and what does the DHT test measure?
DHT, or dihydrotestosterone, is a potent androgen formed from testosterone. The DHT test measures the amount of this hormone in the blood.
2. Is DHT responsible for hair loss?
DHT contributes to male-pattern hair loss in genetically susceptible individuals by affecting hair follicles. However, hair loss can have many causes, and a DHT test alone does not diagnose the reason for hair loss.
3. Can DHT levels be affected by medication?
Yes. Medicines that affect testosterone conversion, particularly 5-alpha-reductase inhibitors, can reduce DHT levels. Inform your healthcare provider about all medicines and supplements you are taking before testing.
