The role of urinary fractionated metanephrines in the diagnosis of phaeochromocytoma.

Abstract

ELISA is a simple and reliable method for measuring uMN and uNMN. The test has a good NPV and can be used as an initial screening test for ruling out phaeochromocytoma. Each hospital will have to define the cut-off value for the assay being used, choosing a proper control population.
