Evaluate hypertension, especially if paroxysmal; evaluate orthostatic hypotension; diagnose pheochromocytoma; preoperative evaluation of suspected childhood adrenal neoplasms (i.e., neuroblastoma); evaluate possible multiple endocrine adenomatosis. Slightly elevated concentrations (100-200 ug/24 hr) of urinary free catecholamines are consistent with essential hypertension; elevated concentrations (>200 ug/24 hr) are suggestive of pheochromocytoma. Further confirmation of elevated urinary catecholamines can be obtained by determination of urinary metanephrines.

Keep specimen refrigerated during collection if possible.
Record the total volume on both container and requisition.
If possible, patient should discontinue all drugs at least 1 week
prior to collection. Some medications known to interfere with the
assay include: Alpha-methyldopa (Aldomet), Isoproterenol, Labetalol,
Mandelamine, Metaclopramide, Acetaminophen (high concentrations only),
Cimetidine, and Catecholamine-containing drugs, MAO inhibitors,
diuretics, vasodilators.
Acid additive (hydrochloric, nitric or acetic acid) is acceptable
but not necessary if the specimen is refrigerated during collection
and transportation.
