Plasma metanephrine levels are widely considered the diagnostic test of choice for phaeochromocytoma in people but have not ...
Background: Measurements of plasma normetanephrine and metanephrine provide a useful diagnostic test for phaeochromocytoma, but this depends on appropriate reference intervals. Upper cut-offs set too high compromise diagnostic sensitivity, whereas set too low, false-positives are a problem. This stu...

Blood collected into k(2)EDTA tubes was processed within 30 min. Separated plasma was aliquoted (脳2) and frozen at -40掳C prior to analyses. One aliquot was analysed for plasma metanephrines using the LDN 2-Met ELISA and the other by LC-MS/MS.The mean bias of -32% for normeta...
