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

  • Multiple Sclerosis Panel 17728

    2 analytes · Serum · Fasting not stated

    Method and collection
    Method
    Isoelectric Focusing (IEF) • Radioimmunoassay (RIA)
    Collection
    Please see the individual tests for specific specimen requirements and stabilities. Both CSF and serum are required specimens. It is preferred that the collection date and time be the same for both; however, it is acceptable for them to be drawn within 48 hours of each other. If no serum is supplied, the client will be contacted to confirm the order. CSF collection tube #4 is preferred. Submitting 4th lumbar puncture collection tube minimizes blood contamination. Transport temperature: Refrigerate CSF specimens at 2-8° C in sterile plastic CSF vial(s) and send refrigerated (cold packs) to the laboratory or freeze CSF specimens at -20° C and send frozen samples to the laboratory on dry ice.

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.
