Panels that include this biomarker

  • Vanillylmandelic Acid (VMA), 24-Hour Urine 004143

    2 analytes · Urine · Fasting not stated · Turnaround 3 - 4 days

    Method and collection
    Method
    Liquid chromatography/tandem mass spectrometry (LC/MS-MS)
    Preparation
    Patient should avoid salicylates, caffeine, phenothiazine, and antihypertension agents. Also coffee, tea, chocolate, fruit (especially bananas and any vanilla containing substances for 72 hours prior to collection).
    Collection
    Instruct the patient to void at 8 AM and discard the specimen. Then collect all urine, including the final specimen voided at the end of the 24-hour collection period (ie, 8 AM the next morning). Measure and record total urine volume. Mix well; send aliquot. Label container with patient's name, date and time collection started, and date and time collection completed.

  • Catecholamines, Fractionated, Urinary Free and Vanillylmandelic Acid (VMA), 24-Hour Urine 286161

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

    Method and collection
    Method
    Liquid chromatography/tandem mass spectrometry (LC/MS-MS)
    Preparation
    See Catecholamines, Fractionated, Urinary Free, 24-Hour Urine [004176] and Vanillylmandelic Acid (VMA), 24-Hour Urine [004143] .
    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 1 test

Single-analyte tests

  • VMA (Vanillylmandelic Acid), 24-Hour Urine without Creatinine 934

    Urine · Fasting not stated · Turnaround Set up: Mon-Fri (p.m.); Report available: 5 days

    Method and collection
    Method
    High Performance Liquid Chromatography (HPLC) • Electrochemical Detection
    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 (including use of nicotine patch), bananas, citrus fruits and strenuous exercise 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.
    Reference notes

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.
