oligoclonal bands

Immunoglobulins found in the cerebrospinal fluid of patients with multiple sclerosis (MS) and, occasionally, in other neurological conditions. They are used as a marker of MS when magnetic resonance imaging studies of the brain are not diagnostic.

The likelihood of progressing from CIS to MS is directly related to the presence of CSF oligoclonal bands (OCB), motor symptoms, and finding of high numbers of MRI white matter lesions.
CSF-specific oligoclonal bands (OCB) were determined by isoelectric focusing in polyacrylamide gels with consecutive silver staining.
Usually the diagnosis of demyelinating disease is supported by the presence of lesions involving the periventricular and corpus callosumareas and the detection of oligoclonal bands from cephalospinal fluid [33, 34].
Using fluid from the lumbar puncture, spinal fluid, we are able to search for specific indicators, including oligoclonal bands, white blood cell count, total protein, and IgG index, that have been associated with MS and other inflammatory diseases.
(1) In 2010, the College of American Pathologists (CAP) began offering a new proficiency survey on oligoclonal bands, OLI, which includes paired CSF and serum samples for laboratories performing these assays.
Cerebrospinal fluid examination showed no oligoclonal bands and magnetic resonance imaging of the spine was normal.
CSF examination was again undertaken and was positive for oligoclonal bands. Repeat testing with the MMSE gave a score of 22/30.
