Catecholamines - urine

Catecholamine measurements in pheochromocytoma and

Dopamine, epinephrine (adrenaline), and norepinephrine are the main catecholamines.

Compared to intraneuronal deamination, extraneuronal O-methylation of norepinephrine and epinephrine to metanephrines represent minor pathways of metabolism.The three catecholamines (norepinephrine, epinephrine, and dopamine) are the principal secretory products of neural tissue.

In patients who are thought to have a pheochromocytoma, biochemical tests should be done to measure the levels of catecholamines (adrenaline, noradrenaline, and dopamine) and metanephrines (i.e. the molecules that catecholamines break down into).
