Catecholamines, Urine

What is the Catecholamines, Urine Test?

The Catecholamines, Urine test measures the levels of catecholamines—epinephrine (adrenaline), norepinephrine (noradrenaline), and dopamine—excreted in urine, usually over a 24-hour collection period. It helps diagnose adrenal gland disorders and rare hormone-producing tumors.

Why is this test done?

Your doctor may recommend this test to:

• Diagnose pheochromocytoma or paraganglioma
• Investigate unexplained high blood pressure
• Evaluate episodes of rapid heartbeat, sweating, or severe headaches
• Monitor treatment of catecholamine-producing tumors
• Assess adrenal gland function
