A testosterone test measures the levels of testosterone in the blood. It is used to determine if a person has normal testosterone levels or if they may have a testosterone deficiency or excess.
The total testosterone test measures the overall amount of testosterone in the blood, including both free testosterone (unbound to proteins) and testosterone that is bound to proteins. Normal total testosterone levels in adult males typically range from 300 to 1,000 nanograms per deciliter (ng/dL).
Abnormal levels of testosterone can have various effects on the body, including changes in mood, energy levels, muscle mass, and sexual function. Low testosterone levels can cause symptoms such as fatigue, reduced libido, erectile dysfunction, and infertility, while high testosterone levels can lead to symptoms such as acne, aggression, and an increased risk of heart disease.
It is important to discuss test results with a healthcare provider to determine the appropriate treatment plan if abnormal testosterone levels are detected.
