A DHT test measures the amount of dihydrotestosterone (DHT) in your blood. DHT is a powerful androgen, a type of hormone that helps develop and maintain male characteristics.
Here's a more detailed breakdown:
-
What DHT is: Dihydrotestosterone (DHT) is a metabolite of testosterone. This means it's created when testosterone is broken down in the body. Although it's derived from testosterone, DHT is a much more potent androgen.
-
What the test measures: The DHT test specifically quantifies the concentration of DHT present in a blood sample.
-
Why the test is done: Doctors order DHT tests for various reasons, including:
- Investigating hair loss (especially male pattern baldness): DHT is a major contributor to androgenetic alopecia.
- Evaluating prostate issues: DHT plays a role in prostate growth, and elevated levels can contribute to benign prostatic hyperplasia (BPH).
- Assessing fertility problems: DHT imbalances can impact sperm production and fertility.
- Diagnosing disorders of sexual development: In some cases, DHT levels can help identify underlying hormonal conditions.
- Suspecting androgen excess or deficiency: The test helps in uncovering the cause of too much or too little androgen activity.
-
How the test is performed: A healthcare professional will draw a blood sample, usually from a vein in your arm. This sample is then sent to a laboratory for analysis.
-
Interpreting the results: DHT levels are compared to established reference ranges. Deviations from these ranges, in conjunction with other clinical findings and tests, help healthcare providers diagnose various conditions.
In summary, the DHT test is a valuable diagnostic tool for assessing hormone levels and identifying potential health issues related to androgen activity.
