The Plasma Metanephrine test measures metanephrine levels in the blood to help diagnose adrenal gland tumors such as pheochromocytoma.
The Plasma Metanephrine test is a blood test used to measure the levels of metanephrines, which are metabolites of catecholamines (adrenaline and noradrenaline). These substances are produced by the adrenal glands and play a key role in regulating blood pressure and stress response.
Elevated levels of metanephrines may indicate the presence of rare adrenal tumors such as pheochromocytoma or paraganglioma. These tumors can cause excessive production of hormones, leading to symptoms like high blood pressure, headaches, sweating, and rapid heart rate.
The purpose of this test is to
