The Metanephrines (Plasma) test is a specialized blood test that measures the levels of metanephrines metabolites (breakdown products) of catecholamines (adrenaline, noradrenaline, and dopamine) in the bloodstream, serving as a highly sensitive and specific marker for diagnosing catecholamine-producing tumors such as pheochromocytoma (a rare tumor of the adrenal glands) and paraganglioma (tumors arising from nerve tissue). For residents of Delhi, this test is particularly valuable in diagnosing and evaluating causes of resistant or episodic high blood pressure (hypertension), severe headaches, excessive sweating, rapid heartbeat, palpitations, anxiety or panic attacks, tremors, unexplained weight loss, high blood sugar levels, and family history of pheochromocytoma or related genetic syndromes such as multiple endocrine neoplasia type 2 (MEN 2), neurofibromatosis type 1, or von Hippel-Lindau disease, helping physicians identify the underlying causes of symptoms such as sudden spikes in blood pressure, pounding headaches, profuse sweating, racing heart, chest pain, shortness of breath, or anxiety attacks, and develop appropriate treatment strategies including surgical removal of tumors, blood pressure management, genetic counseling, or further diagnostic evaluations for optimal cardiovascular health, adrenal function, and overall wellness management.With Seviyaar, Delhi residents can access NABL-certified laboratories that maintain strict quality standards for accurate diagnostic results.
