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

  • Sensory Neuropathy Complete Antibody Panel 15977

    13 analytes · Serum · Fasting required

    Method and collection
    Method
    Immunoassay (IA) • Immunotyping • Immunofixation
    Preparation
    Overnight fasting is required
    Collection
    See individual tests. Multiple tubes required for testing. Cryoglobulin Screen and reflex: 3 mL serum required: 2 mL minimum. Since multiple tubes are needed for this panel, designate one tube exclusively for cryoglobulin and treat it differently from the other tubes collected. Allow blood in the tube designated for cryoglobulin to clot for one (1) hour in a 37° C water bath, incubator, heat block, or heel warmer. After clotting, centrifuge the specimen as quickly as possible. It is not necessary to use a warm centrifuge but do not use a refrigerated one. Decant all of the cryoglobulin serum into one transport vial (do not aliquot any of the cryoglobulin serum into any other tube). Transport at room temperature. Note: If the sample is not kept at 37° C during clotting, the cryoglobulin, if present, can precipitate during centrifugation and be lost in the clot resulting in a false negative result.

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.
