  • VMA (Vanillylmandelic Acid), 24-Hour Urine with Creatinine 39517

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

    Method and collection
    Method
    High Performance Liquid Chromatography (HPLC)
    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.

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.
