What Is a Dihydrotestosterone Test?
A DHT test measures the concentration of dihydrotestosterone in the blood. This hormone, converted from testosterone via the enzyme 5-alpha-reductase, is a key regulator in:
- Male sexual characteristics
- Hair follicle health
- Prostate development
- Hormonal balance in both men and women
The test helps physicians identify hormonal imbalances that may contribute to hair loss, androgenic disorders, or fertility issues.
Why Is a DHT Test Important?
Testing for DHT levels can help:
- Diagnose androgen-related hair loss or thinning
- Evaluate hormonal imbalances in men and women
- Monitor the effects of treatment targeting DHT
- Assess fertility concerns linked to high or low androgen levels
For understanding the impact of elevated DHT on hair and overall health, see our article: Causes of High DHT in Men.
Normal Range for DHT
Normal DHT levels vary depending on age, sex, and laboratory standards:
- Men: Typically 30–85 ng/dL
- Women: Usually 3–30 ng/dL
Deviations from these ranges may indicate androgenic imbalance. Abnormal results should be interpreted alongside testosterone levels and clinical symptoms.

Causes of Abnormal DHT Levels
High DHT levels may result from:
- Overactive 5-alpha-reductase enzyme
- Genetic predisposition
- Certain medications or supplements
- Hormonal imbalances, including elevated testosterone
Low DHT levels may occur due to:
- Hypogonadism (low testosterone)
- Enzyme deficiencies
- Certain medical conditions affecting androgen metabolism

Symptoms That May Lead to Testing
Testing is often recommended if you experience:
- Androgenic hair loss (thinning on the scalp or receding hairline)
- Unexplained infertility
- Acne or oily skin associated with androgen excess
- Prostate enlargement in men
- Hormonal irregularities in women

How the DHT Test is Performed
- Blood is typically drawn in the morning when hormone levels are stable
- No fasting is generally required unless the physician specifies otherwise
- Laboratory analysis uses immunoassay or mass spectrometry techniques to quantify DHT accurately
Interpreting DHT Test Results
- High DHT: May indicate increased androgen activity; often linked to hair loss or prostate issues in men
- Low DHT: Could reflect reduced androgen function; may contribute to hormonal deficiencies
- Always interpret results in the context of total testosterone, free testosterone, and clinical symptoms
Treatment and Management
- Elevated DHT: Management may include 5-alpha-reductase inhibitors, lifestyle adjustments, or natural methods to reduce androgen activity
- Low DHT: May require addressing underlying hormonal deficiencies or optimizing testosterone levels under medical supervision
Is a DHT Test Useful for Women?
Yes, a DHT test may be useful for women in certain situations, especially when symptoms suggest increased androgen activity.
A doctor may request a Dihydrotestosterone test for women who have:
- Hair thinning or unexplained hair loss.
- Unwanted facial or body hair growth.
- Severe or persistent acne.
- Irregular menstrual cycles.
- Suspected androgen excess.
- Possible hormone-related hair loss.
When Should You See a Doctor for Hair Loss?
You should consider seeing a doctor if your hair loss is:
- Persistent.
- Sudden or severe.
- Causing visible bald patches.
- Associated with acne or menstrual irregularities.
- Linked to fatigue, weight changes, or other symptoms.
- Happening with a strong family history of pattern baldness.
- Not improving despite good hair care and nutrition.
Early evaluation can help identify the cause and improve the chances of managing hair loss effectively.
How to Prepare for a DHT Test
Before taking a Dihydrotestosterone test, follow these simple steps:
- Tell your doctor or laboratory about any medications or supplements you take.
- Ask whether the sample should be collected at a specific time of day.
- Morning collection may be preferred in some cases because hormone levels can vary during the day.
- Fasting is usually not required unless your doctor requests it or other tests are being done.
- Bring previous hormone or blood test results if available.
- Do not interpret the result without medical guidance.

Frequently Asked Questions
What is a Dihydrotestosterone test?
A Dihydrotestosterone test is a blood test that measures the level of DHT, a hormone derived from testosterone and linked to androgen activity in the body.
Is a DHT test the same as a DHT blood test?
Yes. A DHT test is usually performed using a blood sample, so it is commonly called a DHT blood test.
Why do doctors request a DHT test for hair loss?
Doctors may request a DHT test for hair loss when they suspect that androgen hormones may be contributing to pattern hair loss or hair thinning.
Does a DHT test diagnose baldness?
No. A DHT test may help evaluate one hormonal factor, but it does not diagnose baldness by itself. Hair loss diagnosis usually requires medical evaluation and sometimes other tests.
Does a DHT test require fasting?
In most cases, fasting is not required for a DHT test. However, you should follow your doctor’s or laboratory’s instructions, especially if other blood tests are being done.
What is the normal range for a DHT test?
The DHT test normal range varies depending on age, sex, laboratory method, and measurement unit. Always compare your result with the reference range shown on your lab report.
What do high DHT levels mean?
High DHT levels may suggest increased androgen activity. They may be associated with hair loss, acne, unwanted hair growth, or other hormonal symptoms, but the result must be interpreted by a doctor.
What do low DHT levels mean?
Low DHT levels may be related to low testosterone, reduced 5-alpha reductase activity, certain medications, or other hormonal conditions.
Is a DHT test useful for women?
Yes. A DHT test may be requested for women with hair thinning, acne, unwanted hair growth, irregular cycles, or suspected androgen imbalance.
How long does it take to get DHT test results?
DHT test result turnaround time may vary from one laboratory to another depending on the testing method and the number of tests requested. In most cases, DHT test results are available within 1 to 3 days, but they may take longer if the sample is sent to a reference laboratory or if additional tests are ordered.
How much does a DHT test cost?
The DHT test price varies between laboratories depending on the testing method, location, and whether the test is ordered alone or within a hormone panel. Contact the laboratory for the latest price.
