Urine: Vanillylmandelic Acid (VMA)

Understanding Vanillylmandelic Acid (VMA)
Vanillylmandelic acid (VMA) is a key metabolic byproduct of catecholamines, including epinephrine (adrenaline), norepinephrine (noradrenaline), and dopamine. Measuring VMA levels in urine provides valuable insight into the function of the adrenal glands and the nervous system.

VMA and Catecholamine-Secreting Tumours
Elevated levels of VMA are often associated with catecholamine-secreting tumours such as neuroblastoma, pheochromocytoma, and other neural crest-derived tumours. These conditions may produce excessive amounts of catecholamines, leading to increased VMA levels detectable through laboratory testing.

Special Requirements for VMA Testing
VMA testing often requires a 24-hour urine collection, and it is essential to record the total volume of the sample. Due to the specialised nature of the test, patients are advised to contact the laboratory in advance for instructions and to schedule an appointment.

Private VMA Testing in Slough and Surrounding Areas
Specialist VMA urine testing is available in Slough, Windsor, Maidenhead, and surrounding Berkshire regions. This diagnostic service supports the early detection and monitoring of adrenal and neural crest tumours, ensuring accurate and timely medical care.
