Ordering Recommendation

May be used in the assessment of multiple sclerosis to detect unique IgG oligoclonal bands in cerebrospinal fluid (CSF) in conjunction with a matched serum specimen. The preferred test to assess for multiple sclerosis is Oligoclonal Band Profile (0080440).

Note

Specimens must be assayed together for interpretation.
This test reports only the number of oligoclonal bands.  A patient is considered positive for CSF oligoclonal bands if there are two or more bands in the CSF immunoglobulin region that are not present in the serum. In order to confirm local production of oligoclonal IgG in CSF, a matched serum sample is required. Oligoclonal bands present in CSF, but not in serum, indicate central nervous system production. Oligoclonal bands are performed using isoelectric focusing and immunofixation.
