CSF is used in the diagnosis of multiple sclerosis (MS) by identifying increased intrathecal IgG synthesis qualitatively (oligoclonal bands). 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 approximately 95% of MS patients, two immunoglobulin G (IgG) oligoclonal bands (OCBs) are detectable exclusively in the cerebrospinal fluid (CSF). Please enable it to take advantage of the complete set of features! These bands in the CSF pattern are produced by a limited number of immunocompetent cell clones, each producing IgG with its own specificity. 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. 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. Oligoclonal bands are visible as an increased concentration of restricted bands of IgG after isoelectric focusing and immunofixation of IgG.

Examining CSF and serum in parallel for OCBs of IgG provides more diagnostic information than examining CSF alone, and the latter is potentially misleading. Multiple sclerosis is a disease that can cause permanent damage to your bodys nerves and the communication mechanisms between your brain and body. In addition, when protein electrophoresis assays are positive for a monoclonal protein, serum and urine immunofixation are indicated for the appropriate identification of the immunoglobulin and the corresponding light chain.
