Tests that Measure Testosterone Levels
Testosterone is a key hormone in men's health, influencing various physical and mental functions. To properly assess testosterone levels, healthcare providers may use several specific tests.
1. Total Testosterone Test
This is the most common test used to measure testosterone levels in the blood. It evaluates the overall amount of testosterone present, providing a baseline for diagnosis.
2. Free Testosterone Test
This test measures the fraction of testosterone that is not bound to proteins in the blood, which is active and readily available for use by the body. It helps in evaluating hormonal balance more accurately.
3. Bioavailable Testosterone Test
This test assesses both free testosterone and the testosterone that is loosely bound to albumin, providing a more comprehensive understanding of the testosterone that is accessible to tissues.
4. Luteinizing Hormone (LH) Test
While not a direct testosterone test, measuring LH levels can help determine the cause of abnormal testosterone levels, as LH stimulates testosterone production in the testes.
5. Follicle Stimulating Hormone (FSH) Test
Similar to the LH test, FSH is assessed to evaluate the function of the testes and overall hormonal health, providing context for testosterone levels.
Consult your healthcare provider to determine which tests are appropriate based on individual symptoms and health status.
