Book a Test- VMA (24 Hrs)

VMA, or vanillylmandelic acid, is a metabolite of the catecholamine hormones epinephrine and norepinephrine. The VMA test measures the level of VMA in the urine over a 24-hour period. This test is used to diagnose and monitor conditions related to excessive production of catecholamines, such as pheochromocytoma, a rare tumor of the adrenal gland. Elevated levels of VMA in the urine can indicate the presence of a pheochromocytoma or other conditions that affect the adrenal gland. The VMA test is often used in conjunction with other tests, such as the catecholamine test, to confirm the diagnosis. The 24-hour urine collection allows for a more accurate measurement of VMA levels, as catecholamine production can vary throughout the day. By measuring VMA levels over a 24-hour period, healthcare providers can gain a better understanding of the body's catecholamine production.
