About This Test
Elevated values of VMA along with other catecholamine metabolites are suggestive of catecholamine secreting tumor like Neuroblastoma, Pheochromocytoma and other Neural crest tumors. VMA levels may also be useful in monitoring patients who are also treated. Elevated levels are suggestive of Pheochromocytoma but not diagnostic.

TAT Policy
The Turnaround Time (TAT) depends on the following factors:
- Registration date and time
- Type of scan or test

In uncommon circumstances, TAT may be delayed due to test complexity or reasons beyond our control. You will be informed of the estimated TAT at the time of registration.
