Catecholamines Free, 24-Hours Urine analysis is a test used to measure levels of catecholamines, which are important hormones that play a key role in the body’s response to stress. This analysis includes measuring dopamine, norepinephrine, and epinephrine in a urine sample collected over a 24-hour period. The sample is collected carefully to provide accurate information about the levels of these hormones. Catecholamine levels are important indicators of adrenal gland health and help diagnose several health conditions, such as neurogenic tumors (such as pheochromocytoma) and disorders related to blood pressure regulation. This test is recommended for individuals who experience symptoms such as high blood pressure, rapid heartbeat, anxiety, or unexplained changes in mood or energy. It is considered a valuable tool for evaluating hormonal disorders and monitoring the body’s response to stress.
