Dihydrotestosterone (DHT) Testing

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.
