Clinical practice guidelines recommend the measurement of metanephrines in plasma or urine over catecholamines for the diagnosis and monitoring of phaeochromocytoma and paraganglioma. Requests received for urine catecholamines testing after 1/10/2019 will be interpreted as a request for urine metanephrines

If VMA or HVA are requested on a child, consult Chemical Pathologist (Dr Lam) 9496 5140
