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

Quest Diagnostics, IgG/Albumin Ratio, CSF 39484

PopulationInterval
IgG, CSF0.8-7.7 mg/dL
Albumin, CSF8.0-42.0 mg/dL
IgG/Albumin Ratio<0.28

Tests

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

    Method and collection
    Method
    Nephelometry
    Collection
    Both CSF & 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.

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.
