Test ID: VMAR
Vanillylmandelic Acid, Random, Urine
Useful For 
Suggests clinical disorders or settings where the test may be helpful
Screening children for catecholamine-secreting tumors with a random urine collection when requesting vanillylmandelic acid only
Supporting a diagnosis of neuroblastoma
Monitoring patients with a treated neuroblastoma
Highlights
Vanillylmandelic acid (VMA) and other catecholamine metabolites such as homovanillic acid (HVA) measurement in urine are used for screening children for catecholamine-secreting tumors such as neuroblastoma and other neural crest tumors and monitoring those who have had treatment for these tumors.
More than 90% of individuals with neuroblastoma have elevated VMA or HVA.
VMA is not the analyte of choice for diagnosis of pheochromocytoma, which is better detected by testing for metanephrines.
Treatment with L-dopa can impact test results and should be discontinued 24 hours prior to collection. Bactrim can impact test results and should be noted at time of collection.
