The plasma free metanephrines test is used to help diagnose or rule out the presence of a rare tumor called a pheochromocytoma or a paraganglioma that releases excess metanephrines. Testing also may be used when a tumor has been treated or removed to monitor for recurrence.Metanephrine and normetanephrine are breakdown products (metabolites) of epinephrine (adrenaline) and norepinephrine. Epinephrine and norepinephrine are hormones called catecholamines that are released into the blood in response to physical or emotional stress and help regulate the flow and pressure of blood throughout the body. (For more on this, see the "What is being tested/" section.) Since pheochromocytomas and paragangliomas produce these hormones in excess, measuring the amount in the blood and/or urine may help detect the tumor.
