Plasma metanephrines in renal failure [PDF]

Kidney International, 2005
Diagnosis of pheochromocytoma in renal failure poses a diagnostic dilemma due to lack of reliability of conventional urinary measurements of catecholamine excess. Measurements of the plasma metanephrines, normetanephrine and metanephrine (the O-methylated metabolites of norepinephrine and epinephrine), provide an alternative diagnostic test.

Biochemical Diagnosis of Catecholamine-Producing Tumors of Childhood: Neuroblastoma, Pheochromocytoma and Paraganglioma

Frontiers in Endocrinology, 2022
Catecholamine-producing tumors of childhood include most notably neuroblastoma, but also pheochromocytoma and paraganglioma (PPGL). Diagnosis of the former depends largely on biopsy-dependent histopathology, but this is contraindicated in PPGL where ...
