Disappearance Rate of Catecholamines, Total Metanephrines, and Neuropeptide Y from the Plasma of Patients after Resection of Pheochromocytoma

Abstract

A larger increase and a longer persistence of total metanephrines (reflecting predominantly sulfo-conjugated metanephrines) than catecholamines and NPY in plasma may contribute to their greater diagnostic accuracy in pheochromocytoma.
