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

    Method and collection
    Method
    Chromatography/Mass Spectrometry
    Collection
    The use of serum separator tube (SST) is not recommended. Obtain serum by drawing blood into an evacuated tube without anticoagulant and with a non-coated interior. Allow 20 minutes for clotting. Centrifuge and immediately separate serum or plasma specimens from the cells into clean, plastic transport tube.

Labcorp 2 tests

Single-analyte tests

  • Carbamazepine, Serum or Plasma 007419

    Serum · Fasting not stated · Turnaround Within 1 day

    Method and collection
    Method
    Immunoassay
    Collection
    Transfer separated serum or plasma to a plastic transport tube. Draw trough levels immediately prior to next dose. Due to variability of absorption, the trough level may not represent the lowest drug level during the dosing interval, so multiple determinations may be necessary in some patients.
    Reference notes
    Therapeutic: In conjunction with other antiepileptic drugs: 4.0−8.0 μg/mL; carbamazepine alone: 6.0−12.0 μg/mL

    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.

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.
