24 Hrs Urinary VMA(Vanillyl Mandelic Acid) is to diagnose or rule out a neuroblastoma or other neuroendocrine tumor; to monitor the effectiveness of treatment. A 24-hour urine sample is preferred; sometimes a random urine sample is acceptable for the test.
This test I done to screen children for catecholamine-secreting tumors with a 24-hour urine collection when requesting testing for only vanillylmandelic acid. To support a diagnosis of neuroblastoma and to monitor patients with a treated neuroblastoma.
