About the test
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.
Who might consider it:
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

Preparation
- Due to changes in testosterone levels throughout the day, two morning (8:00-10:00 a.m.) specimens obtained on different days are recommended by The Endocrine Society for screening.
- Dietary supplements containing biotin may interfere in assays and may skew results to be either falsely high or falsely low. For patients receiving the recommended daily doses of biotin, draw samples at least 8 hours following the last biotin supplementation. For patients on mega-doses of biotin supplements, draw samples at least 72 hours following the last biotin supplementation.
