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

Labcorp 3 tests

Single-analyte tests

  • Alprazolam, Serum or Plasma 842039

    Serum · Fasting not stated · Turnaround 7 - 10 days

    Method and collection
    Method
    Liquid chromatography/tandem mass spectrometry (LC/MS-MS)
    Preparation
    Trough levels are most reproducible.
    Collection
    Serum or plasma should be separated from cells within two hours of venipuncture. Submit serum or plasma in a plastic transport tube.
    Reference notes
    5−25 ng/mL. Note: Some patients respond well to high-dose alprazolam therapy with resultant serum concentrations 25−55 ng/mL.

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.
