URINE V.M.A
The Urine V.M.A test measures the amount of vanillylmandelic acid in the urine, which is a metabolic end product of catecholamines (adrenaline and noradrenaline). These hormones are produced by the adrenal glands and are involved in regulating stress responses, blood pressure, and heart rate.
Elevated V.M.A levels may indicate the presence of certain tumors such as pheochromocytoma (adrenal gland tumor) or neuroblastoma, especially in children. It is often recommended when symptoms like persistent high blood pressure, headaches, sweating, palpitations, or anxiety are present. The test may also be used to monitor treatment in patients diagnosed with these conditions.
The test typically requires a 24-hour urine collection for accurate results. Proper sample collection is important to avoid false results. The Urine V.M.A test helps in early detection and monitoring of hormone-secreting tumors, enabling timely diagnosis and effective management.
