Vanillylmandelic acid (VMA) is a metabolite of catecholamines, primarily produced by the breakdown of epinephrine and norepinephrine. Normal levels of VMA in urine typically range from about 2 to 6 milligrams per 24 hours, though this can vary based on the laboratory and individual factors. Elevated levels may indicate conditions such as pheochromocytoma or neuroblastoma, while lower levels may not typically pose concern. Always consult a healthcare professional for interpretation of test results.
