WebCatecholamines are a group of similar hormones released into the bloodstream in response to physical or emotional stress. The primary catecholamines are: Dopamine, Epinephrine (adrenaline), and. Norepinephrine. Catecholamine testing measures the amounts of these hormones in the urine and/or blood. Urine testing is recommended over blood testing. WebFalse-negatives and false-positives occur. Urine collections for metanephrines are among the best tests for pheochromocytoma. 1 Sheps et al use urinary catecholamine fractionation as confirmation, following a metanephrine test. 1 Neuroblastoma is better worked up with urinary collections for HVA and VMA.
