Labcorp 1 test
Panels that include this biomarker
Catecholamines, Fractionated, Urinary Free, Random Urine 316203
5 analytes · Urine · Fasting not stated · Turnaround 5 - 9 days
Labcorp catalog pageMethod and collection
- Method
- Liquid chromatography/tandem mass spectrometry (LC/MS-MS)
- Preparation
- Avoid patient stress. Many drugs (reserpine and alpha methyldopa, levodopa, monoamine oxidase inhibitors, and sympathomimetic amines) may interfere and should be discontinued two weeks prior to specimen collection. Nose drops, sinus and cough medicines, bronchodilators and appetite suppressants, α2-agonists, calcium channel blockers, converting enzyme inhibitors, bromocriptine, phenothiazine, tricyclic antidepressants, α- and β-blockers, and labetalol may interfere.1 Mandelamine® interferes, but thiazides do not. Caffeine products should be avoided before and during collection. The patient should not be subjected to hypoglycemia or exertion. Increased intracranial pressure and clonidine withdrawal can cause false-positive results.1,2

Catecholamines, Fractionated, Random Urine 5244
4 analytes · Urine · Fasting not stated · Turnaround Set up: Mon-Fri p.m.
Quest Diagnostics catalog pageMethod and collection
- Method
- Liquid Chromatography/Mass Spectrometry (LC/MS)
- Preparation
- It is preferable for the patient to be off medications for a minimum of 18-24 hours prior to collection. However, common antihypertensives (diuretics, ACE inhibitors, calcium channel blockers, alpha and beta blockers) cause minimal or no interference. Patient should avoid alcohol, coffee, tea, tobacco and strenuous exercise for 8-12 hours prior to collection.

We compile this page from named laboratory catalogs, guidelines and studies. Labs calculate reference intervals from the people they test, for one assay method and one population group, so an interval describes that population rather than an optimal target.
