Vanillylmandelic acid (VMA) is the major metabolite of the catecholamines. Increased levels of VMA are often seen in patients with pheochromocytoma. VMA levels are of value for evaluation of hypertension, diagnosis and follow up of neuroblastoma, ganglioneuroma, and ganglioneuroblastoma. Urinary VMA is increased in about 90% of patients with neuroblastoma. Neuroblastoma patients with a Homovanillic acid (HVA) to VMA ratio of less than 1 or greater than 2 have an unfavorable prognosis. [Information from Tietz Clinical Guide to Laboratory Tests, 4th edition, AHB Wu, 2006 and LOINC partner 1, 2007 11 21.] Elevated VMA in cerebrospinal fluid (CSF) without a concomitant elevation of urine VMA may be a marker for neuroectodermal brain tumors and could potentially be used to monitor treatment efficacy.
