Dihydrotestosterone

Dihydrotestosterone

The Dihydrotestosterone (DHT) test is a diagnostic tool used to measure the levels of DHT, a potent androgen hormone, in the blood. DHT is crucial for the development of male characteristics, playing a significant role during fetal development and puberty. It is responsible for the formation of male external genitalia and secondary sexual characteristics. In adulthood, DHT is linked to conditions such as male pattern hair loss and prostate enlargement. The test involves collecting a blood sample, typically serum, which is analyzed in a laboratory. Results are generally available within 3-15 business days, depending on the methodology used. The DHT test is essential for diagnosing conditions like 5-alpha-reductase deficiency and monitoring treatments for androgenetic alopecia and benign prostatic hyperplasia (BPH). Despite its usefulness, the test has limitations, as DHT levels do not always correlate with the severity of related conditions. Understanding DHT's role and accurately measuring it is vital for effective health management.

Purpose of the test

Dihydrotestosterone (DHT) is a potent androgen crucial for male characteristics. It forms from testosterone via 5-alpha-reductase, mainly in genital skin and prostate for AMAB, and skin for AFAB. Key roles include:

- Sexual Development: Essential for male genitalia formation during fetal development and puberty.
- Adult Physiology: Influences male pattern hair loss and prostate enlargement.

DHT blood tests diagnose related conditions and monitor treatment effectiveness. Specimen requirements include serum in a red-top tube. Results typically take 3-15 days. Limitations include DHT's binding to SHBG, affecting measurement accuracy.

Who Should Get Tested

Dihydrotestosterone (DHT) plays a vital role in male development and health. Testing for DHT levels can be crucial for diagnosing and managing certain conditions. Key individuals who may need DHT testing include:

- Those with suspected 5-alpha-reductase deficiency: This genetic disorder affects DHT production, impacting genital development.
- Individuals experiencing androgenetic alopecia: High DHT levels can contribute to hair loss.
- Patients with benign prostatic hyperplasia (BPH): Monitoring DHT can help manage prostate enlargement.
- Those undergoing 5-alpha-reductase inhibitor therapy: Testing ensures treatment effectiveness.

Understanding DHT's role aids in addressing these health concerns.

Blood Test Preparation Guidelines

Time of day

It is recommended to schedule your appointment for blood tests in the morning hours between 7:00-10:00.

Fasting

It is recommended to fast for approximately 12 hours before blood sampling. The last meal of the previous day should ideally be consumed around 6:00 p.m. On the day before the test, avoid heavy and fatty meals as well as alcohol.

Stay hydrated

Drinking water prior to testing can help with sample collection.

Other factors

Tests should not be performed after a sleepless night or intense physical activity. It is recommended to avoid exercise and stress immediately before blood collection and to not smoke. A short rest is recommended.

Medications and supplements:

Blood samples should be collected before the morning dose. Some drugs can interfere with test results. Consult with your doctor whether you can delay your dose because of lab tests.

Biotin supplements:

High doses of biotin supplements can affect test results, causing false elevation or reduction. It's recommended to avoid taking biotin for at least 72 hours before blood collection. If you are taking biotin, inform the personnel collecting the blood so that they can provide specific instructions.

Interpreting Test Results

Understanding test results for Dihydrotestosterone (DHT) is crucial for diagnosing and managing health conditions. Here's a brief overview:

- Role in Development: DHT is vital for male genital development and secondary sexual characteristics.
- Adult Effects: Influences hair loss and prostate health.
- Testing Purpose: Diagnoses conditions like 5-alpha-reductase deficiency and monitors treatment efficacy.
- Specimen Requirements: Serum or plasma, collected in a red-top tube.
- Turnaround Time: Typically 3-15 business days.
- Limitations: Free DHT measurement is more accurate due to binding with SHBG.
