Comments
Any request for plasma catecholamines will be tested for plasma metanephrines instead.
Testing for Plasma Free Metanephrines (the O-methylated metabolites of catecholamines) is now considered
the preferred test in screening for the presence of neuroendocrine secreting tumours such as phaeochromocytomas
and paragangliomas. (Ref: Lenders et al 2022, JAMA 287:1427-1434)
