Diagnostic test for pheochromocytoma

A diagnostic test for pheochromocytoma refers to the clinical and laboratory evaluation used to identify or rule out a pheochromocytoma, which is a rare, usually benign neuroendocrine tumor originating from chromaffin tissue in the adrenal medulla The condition primarily impacts the endocrine and cardiovascular systems in adult and pediatric populations through the excessive, autonomous secretion of catecholamines such as norepinephrine and epinephrine Confirmatory testing identifies autonomous ...

Defining pathophysiologic and clinical features include episodic or sustained hypertension, tachycardia, palpitations, diaphoresis, and severe headaches resulting from hyperadrenergic stimulation

Confirmatory testing identifies autonomous catecholamine overproduction via elevated fractionated metanephrines in plasma or 24-hour urine collections, functional suppression or provocative testing, or targeted diagnostic imaging
