Adrenal Gland Hormone Test - Plasma Free Metanephrines and Normetanephrines Test

Measuring the concentration of free metanephrine and norepinephrine in plasma using microchromatographic techniques (such as HPLC or LC-MS/MS). Metanephrines are metabolites of catecholamines (adrenaline and noradrenaline) and are secreted directly from pheochromocytoma and neuroendocrine tumors. The assay is highly sensitive and specific.
