The Sex Hormone Binding Globulin (SHBG) test measures the level of SHBG in your blood. SHBG is a protein produced mainly by the liver that binds to sex hormones such as oestrogen, dihydrotestosterone (DHT), and testosterone, regulating their availability for tissue use. Although it binds all three hormones, it is especially crucial for managing testosterone levels. Abnormal SHBG levels can signal testosterone-related issues, such as low testosterone in men or high testosterone in women. You might need this test if you have symptoms linked to abnormal testosterone levels. For men, these symptoms include low sex drive, erectile dysfunction, and fertility problems. For women, symptoms might involve excessive hair growth, a deepening voice, irregular or absent menstrual periods, acne, and weight gain. The SHBG test can help clarify testosterone issues when total testosterone levels alone do not explain your symptoms. If you live in Bangalore and are experiencing symptoms like the ones mentioned above, consider getting an SHBG test. This will help diagnose any potential hormonal imbalances and guide treatment approaches.
