Order TestUse
Measurement of fractionated catecholamines (epinephrine, norepinephrine, dopamine, and total catecholamines) in plasma collected in the supine position is used to evaluate disorders involving catecholamine secretion, such as pheochromocytomas and paragangliomas. Supine collection minimizes physiologic elevation related to posture and optimizes diagnostic accuracy.
