What This Test Measures
This test measures dihydrotestosterone (DHT), an androgen hormone produced primarily in the prostate gland, hair follicles, and adrenal glands through the conversion of testosterone. DHT is analyzed using LC/MS methodology on a blood sample.
DHT is an active androgen that plays a role in the development and maintenance of masculine physical characteristics. This test reports your circulating DHT level, giving your healthcare provider a data point to consider alongside your symptoms and medical history.
Benefits
- Measures circulating dihydrotestosterone (DHT) levels in the blood
- Uses LC/MS methodology for laboratory analysis
- Supports evaluation of male pattern hair loss
- Supports evaluation of prostate related concerns
- Helps assess androgen related symptoms in men and women
- Requires no special preparation before testing
Who Is This Test For?
- Individuals experiencing male pattern hair loss
- Individuals with prostate concerns, including prostate enlargement
- Women experiencing irregular or absent menstrual periods
- Individuals experiencing infertility concerns related to androgen levels
- Women experiencing hirsutism or other signs of excess androgen
- Individuals whose healthcare provider wants to evaluate adrenal gland function

FAQ
1. What is the purpose of this hormone test?
This test measures dihydrotestosterone (DHT), a circulating androgen hormone, using LC/MS methodology on a blood sample. It may help a healthcare provider evaluate the cause of male pattern hair loss, prostate problems, or symptoms related to excess androgen production. This test measures DHT alone and is not a hormone panel.
2. Who would benefit from this test?
People experiencing male pattern hair loss or prostate concerns may consider this test. It may also be relevant for women experiencing irregular or absent menstrual periods, infertility, or hirsutism, or for anyone whose provider wants to evaluate adrenal gland function. Results are best reviewed with a healthcare provider familiar with your history.
3. When should I order this test?
You might consider this test if you are noticing male pattern hair loss, prostate related symptoms, or signs of excess androgen such as irregular periods, infertility, or hirsutism. A healthcare provider may also order it to evaluate adrenal gland function. This test does not replace a full medical evaluation.
4. How does this test differ from other hormone tests?
This test measures dihydrotestosterone (DHT) specifically, a circulating androgen that is more potent than testosterone. It does not measure testosterone, adrenal androgens, or any other hormone. Because DHT is analyzed using LC/MS methodology, results reflect this specific analytical approach rather than immunoassay based testing.
5. Do I need to fast before this test?
No special preparation is required for this test.
6. How quickly will I get results?
Results are typically available in 5-10 days. Results may take longer based on weather, holidays, or lab delays.
7. How do I interpret the results?
Interpreting your DHT result depends on factors such as your symptoms, medical history, sex, age, and any medications or supplements you take. Your provider may also consider this result alongside other laboratory findings when forming a clinical picture. An abnormal result does not automatically confirm a hormonal condition, and a normal result does not rule one out.
Disclaimer: Reference ranges may vary by laboratory. Listed ranges are general guidelines and may differ from those used by the performing lab. Always consult your healthcare provider for interpretation.
8. What should I do if my results are abnormal?
If your results fall outside the expected range, review them with a qualified healthcare provider. They can help determine what the result means in the context of your symptoms and history, and whether additional evaluation may be appropriate.
9. How often should I get tested?
Testing frequency should be determined as directed by your healthcare provider based on your individual symptoms and health history.
