Vanillylmandelic acid measurement in the urine is used in the control of mainly children for catecholamine-secreting tumors, in the investigation of arterial hypertension and in the diagnosis and monitoring of neuroblastoma, ganglionuroma and ganglionuroblastoma.

Vanillylmandelic acid (VMA) is the end product of the metabolism of epinephrine (adrenaline) and norepinephrine (noradrenaline) and is excreted in the urine. Concentrations of vanilylmandelic acid and homobanilic acid are elevated in most neuroblastoma patients (more than 90%).

Important Note

Laboratory test results are the most important parameter for the diagnosis and monitoring of all pathological conditions. 70%-80% of diagnostic decisions are based on laboratory tests. Correct interpretation of laboratory results allows a doctor to distinguish "healthy" from "diseased".

Laboratory test results should not be interpreted from the numerical result of a single analysis. Test results should be interpreted in relation to each individual case and family history, clinical findings and the results of other laboratory tests and information. Your personal physician should explain the importance of your test results.

At Diagnostiki Athinon we answer any questions you may have about the test you perform in our laboratory and we contact your doctor to get the best possible medical care.
