Test Overview
Test Methodology

Isoelectric Focusing (IEF) with IgG Immunoblot Detection

Reference Range *

CSF Olig Bands Interpretation: <4 bands. A finding of 4 or more cerebrospinal fluid (CSF)-specific bands (i.e., bands that are present in CSF but are absent in serum) is consistent with multiple sclerosis. The presence of oligoclonal band is unrelated to disease activity.

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

Test Limitations

Increased intrathecal Ig synthesis may occur in other infammatory CSF diseases and, therefore, this assay is not specfic for MS.
