Ranges

Each lab publishes a reference range for the population groups it tests, usually the middle 95% of results. These intervals describe that population, not an optimal or healthy target. How ranges differ

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 .
    Reference notes

    7 analytes · Urine · Fasting not stated · Turnaround 6 - 9 days

    Method and collection
    Method
    Liquid chromatography/tandem mass spectrometry (LC/MS-MS)

    Collection
    Preservative must be added to the container prior to the start of collection. Collect 24-hour urine. Mix well. Send 60 mL aliquot. Record total 24-hour urine volume on test request form. Final pH must be <5. Note: Do not use boric acid or acetic acid as a preservative. Refer to the Preservative Quick Reference Chart in Specimen Collection: Urine Specimens .

Quest Diagnostics 2 tests

Panels that include this biomarker

  • Catecholamines, Fractionated, 24-Hour Urine without Creatinine 318

    4 analytes · Urine · Fasting not stated · Turnaround Set up: Mon-Wed, Fri, Sat a.m.; Report available: 4 days

    Method 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) may cause minimal or no interference. Patient should avoid tobacco, tea, coffee, and strenuous exercise for 8-12 hours prior to collection.
    Collection
    Collect 24-hour urine with 25 mL 6N HCL to maintain a pH ≤3. If no preservative is used, specimen must be stored refrigerated during collection but shipped frozen and pH must be ≤6. Record 24-hour urine volume and patient's age on test request form and on urine container.

  • Catecholamines, Fractionated, 24-Hour Urine with Creatinine 39627

    5 analytes · Urine · Fasting not stated · Turnaround Set up: Mon-Fri p.m.

    Method and collection
    Method
    Liquid Chromatography/Mass Spectrometry (LC/MS)
    Preparation
    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. Patient should avoid alcohol, coffee, tea, tobacco and strenuous exercise prior to collection.
    Collection
    Collect 24-hour urine with 25 mL of 6N HCl to maintain a pH ≤3. If no preservative is used, specimen must be stored refrigerated during collection but shipped frozen and pH must be ≤6. Record 24-hour urine volume and patient's age on test request form and urine container.

Verify these ranges and sources

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.
