| Usage: |
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. |
