Why it is Done

Vanillylmandelic acid (VMA) is one of the breakdown products (metabolites) of epinephrine (adrenaline) and norepinephrine. Epinephrine and norepinephrine belong to a group of similar hormones called catecholamines. This test measures the amount of VMA that is passed into the urine, typically over a 24-hour period, to detect excess epinephrine and norepinephrine. It is used to detect tumors called neuroblastomas and other neuroendocrine tumors.

What is this test

Vanillyl Mandelic Acid help diagnose or rule out a neuroblastoma or other neuroendocrine tumor; to monitor the effectiveness of treatment.
