Tests

Check the catalog code, specimen, method and preparation for every test that measures Voriconazole. Select up to five tests to compare them side by side.

Labcorp 3 tests

Single-analyte tests

  • Voriconazole, Serum or Plasma 700353

    Serum · Fasting not stated · Turnaround 3 - 7 days

    Method and collection
    Method
    Liquid chromatography/tandem mass spectrometry (LC/MS-MS)
    Collection
    Transfer separated serum or plasma to a plastic transport tube. Do not use a gel barrier tube. The use of gel-barrier tubes is not recommended due to slow absorption of the drug by the gel. Depending on the specimen volume and storage times, the decrease in drug level due to absorption may be clinically significant.

Quest Diagnostics 2 tests

Single-analyte tests

  • Voriconazole 94096

    Serum · Fasting not stated · Turnaround Set up: Mon-Sat

    Method and collection
    Method
    Chromatography/Mass Spectrometry
    Reference notes
    Steady state trough levels are achieved within 1 day when an IV loading dose is used and after approximately 5 days of oral or IV therapy without a loading dose. Therapeutic range Prophylaxis: trough >0.5 mcg/mL Therapeutic range for treatment: trough 2.0-5.5 mcg/mL Serum trough levels ≥1 mcg/mL are reported to be associated with lack of therapeutic response and serum trough levels >5.5 mcg/mL have been reported to be associated with reversible neurological adverse events and hepatotoxicity. Co-administration of drugs that metabolically induce or inhibit CYP2C19, or other conditions that affect CYP2C19 may alter voriconazole metabolism.

    Method and collection
    Method
    Colorimetric Micro-broth Dilution
    Collection
    Pure growth of isolated mature colonies of rapidly growing, non-fastidious yeast including Candida spp. and cryptococcus species, and miscellaneous other rapid growing yeast. Identification of the isolate is required.

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.
