In healthy nonobese men aged 19 to 39, harmonized reference work identified an approximate normal range of 264 to 916 ng/dL, with a median near 531 ng/dL. It helps determine who may qualify for therapy alongside symptoms; it does not mean every treated man should be driven to the same number regardless of response or formulation (Mulhall et al., Journal of Urology, 2018). There is no universal magic number that is ideal for every patient on testosterone therapy. For an adult male, 500 ng/dl is within a healthy range. People using this treatment over the long term could experience potentially severe side effects, such as an increased risk of heart problems. Treatments for low or high testosterone will depend on the underlying health condition. The total testosterone level test is a blood test. Health professionals use LH and FSH readings to explore a possible cause of low testosterone and diagnose hypogonadism. A general rule of thumb is that free testosterone less than 50–65 pg/mL is considered low. Because of this, free testosterone is theorized—although still debated—to be a good proxy for how much of your testosterone is actively working. Bioavailable testosterone includes testosterone that is free or loosely attached to albumin. For all these reasons, your healthcare provider will carefully consider if TRT is safe for you based on your unique characteristics. But there aren’t many studies on the long-term effects of TRT (for example, over decades). If you don’t have these health concerns, TRT is generally safe. Certain existing health conditions make TRT unsafe, like prostate cancer, breast cancer and heart failure. By age 70, levels may be 40-50% lower than in young adulthood. Treatment decisions should be based on both lab values and symptoms, not numbers alone. At Highland Longevity, we offer comprehensive testosterone evaluation including total testosterone, free testosterone, SHBG, and other relevant markers. The reasons for testosterone tests include having symptoms of hormone imbalance or health concerns. Understanding testosterone levels is important for detecting hormone imbalances and supporting optimal health and well-being. For females, the test is mostly used for symptoms of high T levels. You may need this test if you have symptoms of abnormal testosterone levels. A testosterone levels test may be used with other tests to help your provider find the cause of abnormal testosterone levels.
