Panels that include this biomarker

  • Catecholamines, Fractionated, Urinary Free, 24-Hour Urine 004176

    5 analytes · Urine · Fasting not stated · Turnaround 4 - 7 days

    Method and collection
    Method
    Liquid chromatography/tandem mass spectrometry (LC/MS-MS)
    Preparation
    Avoid patient stress. Many drugs (reserpine and α-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
    Collection
    Instruct the patient to void at 8 a.m. and discard the specimen. Preservative must be added to the container prior to the start of collection. Then collect all urine including the final specimen voided at the end of the 24-hour collection period (i.e., 8 a.m. the next morning). Label container. Keep collection on ice. Measure and record total urine volume on the test request form. Remove 20 mL aliquot. pH should be <5. Refer to the Preservative Quick Reference Chart in Specimen Collection: Urine Specimens .

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.
