The three catecholamines (norepinephrine, epinephrine, and dopamine) are the principal secretory products of neural tissue. Clinically, the measurement of circulating catecholamines is valuable in the diagnosis of catecholamine secreting tumors associated chiefly with hypertension (pheochromocytomas, neuroblastomas, and gangliomas) and with the evaluation of orthostatic hypotension.

Collect 24-hour urine with 25 mL of 6N HCL to maintain a pH below 3.
Urine without preservative is acceptable if pH is below 6 and the
sample is shipped frozen. Record 24-hour urine volume on test request
form and urine vial. It is preferable for the patient to be off
medications for three days prior to collection. However, common
antihypertensives (diuretics, ACE inhibitors, calcium channel
blockers, alpha and beta blockers) cause minimal or no interference.
