The Sex Hormone Binding Globulin (SHBG) test in serum is an important test used to assess the balance of sex hormones in the body. This test measures the amount of protein that binds to hormones such as testosterone and estrogen, helping to understand the levels of these active hormones. SHBG levels are influenced by several factors, including age, sex, weight, and health conditions such as obesity or diabetes. This test is useful in diagnosing a range of medical conditions, such as endocrine disorders or fertility issues, and is also used to evaluate the effectiveness of hormone therapies. The SHBG test helps doctors make informed decisions regarding treatment plans and monitor any changes in patients’ health status.
