The Vanilmandelic Acid (VMA), 24-Hour Urine Test measures the level of VMA, a breakdown product of catecholamines (dopamine, norepinephrine, and epinephrine), in the urine over a 24-hour period. Catecholamines are hormones produced by the adrenal glands that are involved in the body’s stress response. Elevated VMA levels may indicate certain types of tumors, such as pheochromocytoma or neuroblastoma.

    Why It’s Done:
    This test is used to:
    • Diagnose pheochromocytoma: A rare tumor of the adrenal glands that can cause excessive catecholamine production.
    • Assess neuroblastoma: A cancer of the nerve tissue that primarily affects children, where VMA levels may be elevated.
    • Monitor treatment: In patients with diagnosed pheochromocytoma or neuroblastoma, to check the effectiveness of treatments or surgery.
    • Evaluate catecholamine-related conditions: Such as hyperthyroidism or stress-related disorders.

    Sample Collection:
    • A 24-hour urine sample is required for this test.
    • The sample must be collected over a full 24-hour period to ensure an accurate measurement of VMA levels.
    • The sample should be stored properly during the collection period, and in some cases, a preservative may be added.
