Clinical Use

Not recommended for evaluation of pheochromocytoma or paraganglioma. Use to evaluate clinical symptoms of excess catecholamine secretion. For the assessment of pheochromocytoma and paraganglioma, refer to Metanephrines, Plasma (Free) (0050184) or Metanephrines Fractionated by HPLC-MS/MS, Urine (2007996). Small increases in catecholamines (less than 2 times the upper reference limit) usually are the result of physiological stimuli, drugs, or improper specimen collection. Significant elevation of one or more catecholamines (2 or more times the upper reference limit) is associated with an increased probability of a neuroendocrine tumor. Measurement of plasma or urine fractionated metanephrines provides better diagnostic sensitivity than measurement of catecholamines.

Reference Range

Dopamine – 18 years and older seated (15 min) OR supine (30 min): Less than orequal to 240 pmol/L
Epinephrine – 18 years and older seated (15 min): Less than or equal to 330 pmol/L OR supine (30 min):Less than or equal to 265 pmol/L
Norepinephrine -18 years and older seated (15 min): 1050-4800 pmol/L ORsupine (30 min):Less than or equal to 680-3100 pmol/L Medications may interfere with catecholamines and metabolites. The effect of drugs on catecholamine results may not be predictable.
