Vanillylmandelic Acid (VMA) is an end-stage metabolite of the catecholamines epinephrine and norepinephrine. It is produced via intermediary metabolites. VMA is found in the urine, along with other catecholamine metabolites. This test is used as a marker for three types of tumors: pheochromocytoma, neuroblastoma and ganglioneuroma. Patients with essential hypertension occasionally have borderline increased values for urinary VMA. Other related tests: Catecholamines and Metanephrines.
