Gurtner KM, Shosha E, Bryant SC, Andreguetto BD, Murray DL, Pittock SJ, Willrich MAV. 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. A normal result is no bands or just one band. You may also sit up and bend over. BMJ Case Rep. 2020 May 27;13(5):e234316. If the result is negative, it is safe to conclude that a pure kappa or lambda light chain is present. 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). 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. After a few moments, it will begin working. The determination of intrathecal IgM, including IgM/lipid-specific IgM OCBs, on the other hand, seems to be of prognostic relevance and is associated with a more aggressive disease course.

Their presence suggests inflammation of the central nervous system due to infection or another disease. How is a CSF sample collected for an immunofixation test? Tests that show an elevated level of OCBs indicate that a person might be living with MS. Approximately 2% to 3% of clinically confirmed MS patients show little or no evidence of oligoclonal bands in the CSF; however oligoclonal bands may develop as the disease progresses. A negative urine or serum immunofixation result does not always rule out a plasma cell dyscrasia, as a nonsecretory or oligosecretory multiple myeloma can present with a negative immunofixation finding in both the urine and the serum. Immunofixation consists of an electrophoresis phase and a fixation phase. CSF is a clear, colourless fluid found in your CNS. (2016). Oligoclonal bands are visible as an increased concentration of restricted bands of IgG after isoelectric focusing and immunofixation of IgG. CSF is used in the diagnosis of multiple sclerosis (MS) by identifying increased intrathecal IgG synthesis qualitatively (oligoclonal bands). Before -, N Engl J Med.

Oligoclonal bands: An immunological and clinical approach. Collection Instructions: Label specimen as spinal fluid. It means that the immunoglobulins are being produced in your CNS. Increased intrathecal Ig synthesis may occur in other inflammatory CSF diseases and, therefore this assay is not specific for MS. In particular, cerebrospinal fluid (CSF)-restricted OCBs represent a hallmark of multiple sclerosis (MS), where they can be detected in > 90% of cases and support its diagnosis, although a specific causative agent inducing B cell activation has not yet been identified. However, their presence alone does not mean that a person definitely has MS. A doctor will need to conduct additional testing to determine the presence of MS. To test OCB levels, a doctor will need to perform a CSF oligoclonal banding test, which involves inserting a needle into the spine to collect CSF. The detection of increased intrathecal immunoglobulin synthesis is the basis for current diagnostic laboratory tests for MS.
