About this test
The Total Testosterone Test measures the overall amount of testosterone in the blood. Testosterone is the main male sex hormone, but it is present in everyone and plays a role in muscle mass, bone density, mood, and sexual function. Total testosterone includes both free testosterone and testosterone bound to proteins. This test is used when levels are suspected to be too high or too low. Because levels vary through the day, your provider may recommend a specific collection time. Results are interpreted with your age, symptoms, and other hormone tests.
What this test measures
- Total Testosterone Measures the overall level of testosterone in the blood, including bound and free forms.
Who this test may be right for
- Men with low energy, mood changes, or reduced libido being evaluated.
- Individuals whose provider suspects testosterone levels are too high or too low.
- People being monitored during treatment for a known hormone condition.
- Anyone whose provider wants a baseline testosterone measurement.
- People being evaluated for delayed or early development concerns.
Before your visit
- Your provider may recommend a morning collection because testosterone levels are often higher earlier in the day.
- No fasting is required unless your provider gives other instructions.
- Tell your provider about any hormone medications or supplements you take.
- Avoid strenuous exercise right before collection if your provider advises.
Understanding your results
The report shows your total testosterone level compared with the reference range, which depends on age and sex. A low level may be associated with certain hormone patterns, while a high level may have other causes, but a single value is not diagnostic. Testosterone varies through the day and can be affected by medications and other health factors. Discuss any abnormal or unexpected result with a healthcare provider, who can interpret it with your symptoms and decide whether additional testing is needed.
