DIHYDROXY TESTOSTERONE

This Test measures the level of dihydrotestosterone (DHT), a potent male sex hormone derived from testosterone. DHT plays a key role in the development of male characteristics, hair growth, and prostate function.

The purpose of the test is to:

• Measure DHT hormone levels in the blood
• Assess androgen (male hormone) balance
• Investigate hair loss or excessive hair growth
• Help diagnose hormonal or endocrine disorders

DIHYDROXY TESTOSTERONE Test

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.

DIHYDROXY TESTOSTERONE Test is Recommended for Individuals:

• Men with suspected androgen-related hormonal abnormalities
• Individuals being evaluated for abnormalities in testosterone metabolism
• Patients with certain disorders of sexual development or puberty
• Men with unexplained changes related to androgen activity
• Selected patients being evaluated for male-pattern hair loss
• Women with symptoms of excess androgen activity, such as excessive facial or body hair, when advised by a healthcare provider
• Patients undergoing evaluation for conditions involving 5-alpha-reductase activity

FAQs

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.
