The VMA blood test is not common; VMA is typically measured in urine. The test helps detect and monitor neuroendocrine tumors, such as pheochromocytoma and neuroblastoma.
How do you prepare for a vanillylmandelic acid test?
To prepare for a vanillylmandelic acid (VMA) test, avoid certain foods and medications before collection. Your doctor may provide specific instructions, often including restrictions on coffee, chocolate, and certain drugs.
What causes high VMA in urine?
Elevated VMA levels in urine may indicate neuroendocrine tumors, stress, medications, or certain foods. Neuroblastoma, a childhood cancer, can also cause increased VMA excretion.
What happens if VMA is high?
A high VMA result suggests potential neuroendocrine tumor activity. Further diagnostic tests and imaging may be needed to confirm the presence and location of the tumor. Early detection allows for timely intervention and treatment.
