Testosterone Test: What to Expect and How to Interpret Results

What to Expect from a Testosterone Test?
A testosterone test measures the level of testosterone, a key hormone in both men and women, but especially important for male sexual development and health. During the test, a healthcare provider draws blood from a vein, usually from your arm. This is a simple procedure that typically takes a few minutes. The results help diagnose conditions like hypogonadism (low testosterone), infertility, or hormonal imbalances. Normal levels vary by age and sex, so understanding your results in context is essential for proper diagnosis.

What to Expect and How to Interpret Testosterone Test Results

A testosterone test is a vital diagnostic tool, particularly in evaluating male sexual health, but also important for women. Here's what you can expect and how to interpret your results:

Test Procedure
The test is a standard blood test where a sample is drawn from a vein in your arm. It usually takes a few minutes and may be done in the morning when testosterone levels are highest. No special preparation is needed, but your doctor might advise fasting.
Understanding Your Results
- Normal Ranges:
  - In adult men, normal testosterone levels range between 300-1,000 ng/dL.
  - In adult women, normal levels range from 15-70 ng/dL.
- Low Testosterone (Hypogonadism):
  Low levels may indicate conditions such as hypogonadism, where the body produces insufficient testosterone, leading to symptoms like fatigue, decreased libido, and infertility.
- High Testosterone:
  High levels can occur due to conditions like polycystic ovary syndrome (PCOS) in women or the use of anabolic steroids. In men, abnormally high testosterone may lead to aggressive behavior or other health issues.
Follow-up and Treatment:
Depending on the results, further testing, lifestyle changes, or hormone therapy might be recommended.
