Testosterone
About Test
The Testosterone test measures the level of testosterone, a key hormone in the body, in the blood. Testosterone is primarily produced in the testes in men and the ovaries in women, with small amounts produced by the adrenal glands in both sexes. It plays a crucial role in the development of male sexual characteristics, muscle mass, bone density, and overall energy levels. In women, it contributes to bone strength, muscle mass, and sexual function.
This test is used to diagnose and monitor conditions related to abnormal testosterone levels. Elevated testosterone levels in men can indicate conditions such as testosterone replacement therapy misuse, adrenal tumours, or polycystic ovary syndrome (PCOS) in women. Low testosterone levels can be associated with conditions such as hypogonadism, certain types of pituitary disorders, or age-related testosterone decline.
Monitoring testosterone levels helps healthcare providers assess hormonal balance, diagnose endocrine disorders, and guide treatment strategies to maintain optimal hormone levels and support overall health and well-being. Regular testing is important for managing conditions related to hormonal imbalances effectively.
