The Total Testosterone test measures the total amount of testosterone in your blood, including both bound and free forms. Testosterone is a key hormone responsible for various functions in both men and women, including muscle mass, energy levels, and sexual health. Abnormal testosterone levels can lead to a variety of symptoms, such as fatigue, low libido, and mood swings. This test is essential for anyone looking to understand their hormonal balance, particularly those experiencing symptoms related to low testosterone levels or andropause in men.
