What this test is
Testosterone testing measures the level of testosterone, a hormone important for sexual development, muscle mass, and mood in both men and women. It is used to investigate symptoms such as fatigue, low sex drive, or infertility. The test can also monitor the effects of hormone therapy.
What it measures
- Total Testosterone — reflects the total amount of testosterone in the blood
- Free Testosterone — reflects the unbound, biologically active portion of testosterone
- Bioavailable Testosterone — reflects testosterone that is loosely bound and available to tissues
- Sex Hormone Binding Globulin (SHBG) — reflects a protein that binds testosterone and affects its availability
What the test involves
The test involves a standard blood draw, usually from a vein in the arm. In some cases, a saliva or urine sample may be collected instead, depending on the lab's protocol.
Why it is often ordered
A clinician may order testosterone testing to evaluate symptoms like decreased sex drive, erectile dysfunction, or unexplained fatigue. It can also help diagnose conditions such as hypogonadism or testosterone excess, and to monitor hormone replacement therapy.
Preparation
Preparation instructions vary by laboratory and may include fasting or timing the test for the morning. Always follow the specific instructions provided by the collection lab.
How results are reported
Results are typically reported as a numeric value with a reference range, which varies by laboratory and by the method used. Your clinician will interpret your results in the context of your symptoms and medical history.
