Pathology. The symptoms of multiple sclerosis are unpredictable, varying from person to person and fluctuating over time. A serum sample is taken at the time of the lumbar puncture as oligoclonal bands may be present in CSF alone or CSF and blood. CSF is used in the diagnosis of multiple sclerosis (MS) by identifying increased intrathecal IgG synthesis qualitatively (oligoclonal bands). OCBs can also be present in other central nervous system (CNS) disorders, including antibody-mediated, inflammatory, infectious, and neurodegenerative conditions, as well as in both chronic and early disease stages, suggesting the occurrence of primary or concomitant immune-mediated processes. Bands present only in the CSF indicate local CNS disorders, especially multiple sclerosis, and sometimes other conditions such as CNS infection, inflammation or neoplasia (tumours or cancers). In some cases, all the lanes are homogeneously darkened to the same degree. Interpretation. On the contrary, a persistent monoclonal protein despite treatment is a sign of refractory disease. doi: 10.1371/journal.pone.0186842.

Two or more oligoclonal IgG bands (OB) detected by separation of cerebrospinal fluid (CSF) proteins while not demonstrable in corresponding serum reflect a local B-cell response accompanying central nervous system (CNS) inflammation. The results show that the individual MS patient had oligoclonal IgG bands in serum, differ with respect to number, isoelectric point and L chain type from the oligoclonal IgG profile seen in the patient's CSF. After a few moments, it will begin working. 22:1262-8.

Federal government websites often end in .gov or .mil. The separated immunoglobulins (Ig) are visualized by an IgG immunoblot, and OCBs that are present in the CSF and not in the serum are reported. If the CSF protein concentration is >200 mg/dL, even high immunoglobulin production in the central nervous system can be obscured by the presence of plasma proteins. The diagnostic process will also involve the doctor: If elevated OCB levels are present but a person does not fit the criteria for MS, a doctor will likely continue to search for the underlying cause. The separated immunoglobulins (Ig) are visualized by an IgG immunoblot, and OCBs that are present in the CSF and not in the serum are reported. In a cohort of 1307 patients analyzed in 2018, where 159 had demyelinating disease, the Mayo Clinic oligoclonal banding test had a clinical sensitivity of 74% and clinical specificity of 89%, with a ROC AUC of 0.813 when 2 or more unique cerebrospinal fluid bands are used as a cutoff for positive. Saint Luke's Regional Laboratories began using this method in September 2003. During the fixation phase, antiserum containing anti-IgG, anti-IgA, anti-IgM, anti-light chain kappa, or anti-light chain lambda is inoculated with the serum proteins.
