The vanillylmandelic acid (VMA) test is primarily used to detect and rule out tumors called neuroblastomas in children with an abdominal mass or other symptoms suggestive of the disease. It may be ordered along with an homovanillic acid (HVA) test to help diagnose a neuroblastoma, to monitor the effectiveness of treatment, and to monitor for neuroblastoma recurrence.A urine creatinine test is typically also ordered, especially with random urine testing, and tests results are frequently reported as VMA-to-creatinine and HVA-to-creatinine ratios. Since creatinine is a substance that is passed into the urine at a relatively constant rate, it serves as a comparison to the amounts of VMA and HVA.A VMA test was once frequently ordered to detect pheochromocytomas, but the preferred tests are now plasma free metanephrines, urine metanephrines, and urine or plasma catecholamine tests. The VMA test may still be ordered along with one or more of these tests to help detect and rule out a pheochromocytoma.
