This test measures the level of testosterone in the body, which is mostly bound to transport proteins like sex hormone binding globulin (SHBG). Only a small fraction of testosterone is free and active. Understanding testosterone levels can help in diagnosing and treating conditions such as erectile dysfunction, infertility, gynecomastia (enlarged breast tissue in men), osteoporosis, and in assessing hormone replacement therapy.
What patients is this test right for?
This test may be recommended for men showing symptoms of low testosterone levels or hormonal imbalance, including:
- Difficulty achieving or maintaining an erection
- Low sex drive
- Infertility
- Development of breast tissue
- Loss of bone mass (osteoporosis)
- Low energy levels and mood swings
