About Dihydrotestosterone (DHT)
The DHT test is used to measure the concentrations of the dihydrotestosterone hormone in the blood sample. This hormone is produced by the reduction of testosterone by 5-alpha reductase. DHT plays an important role in the formation of masculine characteristics such as facial hair, a deep voice, and the development of male reproductive organs. Abnormal DHT levels can lead to various complications based on one's age and sexual development stage. Thus, it is recommended to undergo this test to aid in the diagnosis of various conditions, including prostate cancer, polycystic ovary syndrome (PCOS), etc.

Test preparation
No special preparation is required for this test. Some medications might affect the test results, so be sure your healthcare provider is aware of any prescription drugs, over-the-counter medicines, or dietary supplements you are taking.
Interpretation of the Test Results
The reference ranges for the DHT test may vary based on age, gender, and from lab to lab. The normal reference ranges are given in nanograms per decilitre (ng/dL).
| Parameters | Reference range (males) | Reference range (females) |
|---|---|---|
| DHT | 30-85 ng/dL | 4-22 ng/dL |
Deviation from normal results indicates the following:
- Elevated levels of DHT may be caused due to prostate cancer, idiopathic hirsutism (presence of coarse hairs), and polycystic ovary syndrome (PCOS).
- Low levels of DHT may be caused due to Klinefelter's syndrome (extra copy of the X chromosome), azoospermia (no sperm in the ejaculate), and anorchia (absence of both testes at birth).
FAQs on Dihydrotestosterone (DHT)
A blood sample is collected from a vein in your arm using a small needle. Usually, this procedure does not take more than 5 minutes.
No, there are no associated risks with the dopamine test. It is a simple blood test that carries minimal risks, such as experiencing a slight sting or bruise at the needle insertion site. Typically, these discomforts subside within a short period of time, ranging from a few minutes to a couple of hours. In rare cases, there is a possibility of infection at the needle insertion site.
The dopamine test result is usually available within 3-8 days after the sample collection. However, this duration may vary depending on the diagnostic clinic.
Yes, certain medications such as antiemetic drugs (used to treat nausea and vomiting) and antipsychotic drugs can have an impact on dopamine levels. To ensure accurate results, it is important to inform the healthcare provider about all the medications you are currently taking prior to the test.
Dopamine is often referred to as the "feel-good" hormone because it is responsible for providing a sense of pleasure and motivation. Engaging in pleasurable activities prompts the brain to release large amounts of dopamine, resulting in a heightened feeling of well-being and a desire for more. This explains the addictive nature of junk food and sugar, as they stimulate the release of dopamine in the brain, creating a sensation of euphoria and a craving to repeat that experience.
