Test Overview

Test Methodology

Nephelometry

Test Usage

The level of CSF albumin is used as a reference to indicate whether an increase of the IgG is due to local secretion or to increased permeability of the blood capillaries. CSF IgG is frequently elevated in multiple sclerosis; elevations occur also in CNS syphilis, postvaccinial encephalitis, subacute sclerosing leukoencephalitis, and other primary inflammatory states of the CNS.

Reference Range

CSF IgG: 0-4.5 mg/dL; CSF Albumin: 5-34 mg/dL; CSF IgG/Albumin ratio: 0.02-0.20

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
