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/Alb Ratio, CSF. Select up to five tests to compare them side by side.

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.
