What Does VMA Stand For?

VMA stands for Vanillylmandelic Acid

Vanillylmandelic Acid (VMA) is a phenolic compound and a significant metabolite of catecholamines, specifically epinephrine and norepinephrine. It is primarily excreted in urine and is commonly used as a biomarker in clinical diagnostics, particularly for the detection and monitoring of certain neuroendocrine tumors, such as pheochromocytomas and neuroblastomas. Elevated levels of VMA in urine can indicate abnormal catecholamine metabolism, aiding in the diagnosis and management of these conditions.
