Dihydrotestosterone, (DHT) LC/MS/MS (Quest Diagnostics)

HSA/FSA reimbursable
DHT is a potent androgen derived from testosterone via 5-alpha-reductase activity. 5-alpha-reductase deficiency results in incompletely virilized males (phenotypic females). This diagnosis is supported by an elevated ratio of testosterone to DHT.

What is a Dihydrotestosterone Test?
A Dihydrotestosterone test is used to measure the amount of DHT, which plays a role in causing male pattern baldness and prostate issues among other problems, in a patient's blood. DHT is closely related to testosterone, though it is a much more potent form required for sexual development in men. Aging men tend to have higher levels of DHT that may potentially lead to issues with lower bone density and muscle strength, poor red blood cell production, as well as lowered sex drive and sperm production.
Who May Need a Dihydrotestosterone Test?
Dihydrotestosterone tests are primarily designed for men and women on testosterone replacement therapy whose physicians want to ensure their levels are within an optimal range. They are also utilized to identify issues with DHT in men who are experiencing problems with lowered sex drive, infertility, extreme hair loss, and lower bone density and muscle strength. In women, the test is useful in determining if high levels of DHT are contributing to hair loss or the presence of male characteristics such as excess facial or body hair.
What Should I Expect from My Dihydrotestosterone Test?
A Dihydrotestosterone test begins with a blood sample being drawn from a patient in order for it to be analyzed by a medical laboratory. Dihydrotestosterone tests do not require patients to refrain from eating for any time period prior to the test being performed. Common reference ranges do exist among dihydrotestosterone results, though some labs may have different ranges for you and your physician. Speak to your doctor regarding your results to get more information on how they concern you and your health specifically.
FAQ
-
What is dihydrotestosterone?
Dihydrotestosterone, also known as DHT or 5-alpha dihydrotestosterone, is an androgen sex hormone produced primarily in the testes and adrenal glands. DHT plays a major role in:
- Male pattern baldness
- Prostate growth
- Development of male sex organs (testes and penis)
-
Why is a dihydrotestosterone blood test important?
The dihydrotestosterone blood test is important because it provides information on an individual's sex hormone levels.
Dihydrotestosterone is an androgen hormone, part of a complex group of hormones responsible for male secondary sex characteristics. This test can determine if there is a potential issue with testosterone and your body's ability to convert this hormone into dihydrotestosterone. Some symptoms of low DHT are:
- Male infertility
- Erectile dysfunction
- Increased body fat in different areas
- Delayed development of sex organs
*Decreased sex drive
-
Who should get a dihydrotestosterone blood test?
Dihydrotestosterone helps fuel the development of male sex characteristics and regulates a man's reproductive system. You may want to have this test done if you have male-specific health concerns, such as:
- Erectile dysfunction
- Suspicion of a low sperm count
- Low testosterone production
If your results are abnormal, speak to your doctor for guidance on further testing or to explore treatment options.
-
Does DHT build muscle?
DHT does help in muscle building. Some studies have shown that DHT may increase the force production in fast-contracting muscles and decrease it in slow ones. These findings are leading scientists to suggest that DHT is a great muscle-building hormone, as much as testosterone.
