What is 24 Hrs Urinary Vanillyl Mandelic Acid (VMA)?

This test measures the amount of Vanillyl Mandelic Acid (VMA) excreted in your urine over a 24-hour period. VMA is a breakdown product of certain hormones (catecholamines) produced by the adrenal glands.

Why is this test important?

Elevated VMA levels can indicate the presence of rare tumors of the adrenal glands or nervous system, such as pheochromocytoma or neuroblastoma. It's crucial for diagnosis and monitoring of these conditions.

How to Prepare

You will need to collect all your urine for a full 24-hour period. Certain foods, medications, and stress can affect results, so specific dietary and medication restrictions may be required before and during collection. Consult your doctor for detailed instructions.
