metanephrine
(′med·ə′ne′frən)
(biochemistry) An inactive metabolite of epinephrine (3-O-methylepinephrine) that is excreted in the urine; it is recovered and measured as a test for pheochromocytoma.

metanephrine
or metadrenaline
3-O-methylepinephrine; an inactive metabolite of epinephrine, produced by the action of catechol O-methyltransferase. Small quantities are normally found in the urine, and larger amounts occur in the urine of patients with catecholamine-secreting tumours.

Metanephrine is a metabolite of epinephrine created by action of catechol-O-methyl transferase on epinephrine. An article in the Journal of the American Medical Association, 2002, indicated that the measurement of plasma free metanephrines is the best tool in the diagnosis of pheochromocytoma, an adrenal medullary neoplasm.[1]
