Plasma and urinary metanephrines determined by an enzyme immunoassay, but not serum chromogranin A for the diagnosis of pheochromocytoma in patients with adrenal mass.


Adrenal pheochromocytomas are neoplasms characterized by catecholamine excess. Determination of metanephrines by high-pressure liquid chromatography has been well established for the diagnosis of pheochromocytomas, demonstrating high sensitivity and specificity.
