The Free Metanephrines test in (EDTA) plasma measures three metabolites of the catecholamines epinephrine, norepinephrine and dopamine. These catecholamines are made in the adrenal gland to regulate the heartbeat, blood pressure and glucose concentrations. They can also be released in excess by rare tumors, such as pheochromocytomas and paragangliomas, on adrenal and extra-adrenal chromaffin tissue. The majority of these tumors release epinephrine and norepinephrine. Some rare tumors however excrete mostly, or sometimes solely, dopamine.
