The Testosterone test evaluates levels of this crucial hormone to diagnose and manage conditions related to hormonal imbalances. Low testosterone levels in men can result in symptoms such as reduced libido, erectile dysfunction, fatigue, and decreased muscle mass. In women, low levels might cause symptoms like reduced libido and mood changes. Elevated testosterone levels may be linked to conditions like PCOS in women or testosterone-secreting tumors in both sexes. The test is essential for assessing reproductive health, diagnosing hormonal disorders, and guiding appropriate treatment.
