Plasma-Free Metanephrine and Normetanephrine Quantification for Clinical Applications Validated by Combining Solid-Phase Extraction and HPLC-MS/MS [PDF]
Plasma-free metanephrines are the most sensitive and specific biochemical markers for diagnosing catecholamine-secreting tumors, such as pheochromocytoma and paraganglioma.

Optimized procedures for testing plasma metanephrines in patients on hemodialysis [PDF]
Diagnosis of pheochromocytomas and paragangliomas in patients receiving hemodialysis is troublesome. The aim of the study was to establish optimal conditions for blood sampling for mass spectrometric measurements of normetanephrine, metanephrine and 3 ...

Urine-normetanephrine, a predictor of mortality risk in patients with adrenal adenomas [PDF]
Urine-metanephrines are used in the screening for pheochromocytomas in patients with adrenal incidentalomas, but their potential as markers for mortality in patients with adrenal adenomas has not been studied. A retrospective cohort study was designed to

Measuring of metanephrine by UV-Vis peak of surface absorption Plasmon resonance of silver nanoparticles by response surface methodology [PDF]
A simple and low-cost spectrophotometry method was proposed based on resonance Plasmon peak of silver nanoparticles for measurement of metanephrine(MN) drug. This method was based on reducing property of metanephrine and it was founded that this compound

Urinary Free Metanephrines for Diagnosis of Pheochromocytoma and Paraganglioma [PDF]
Background Pheochromocytoma and paraganglioma (PPGL) is diagnosed through biochemical confirmation of excessive catecholamines in urine and plasma. Recent technological developments have allowed us to measure urinary free metanephrines; however, the ...
