The results can help diagnose conditions of the central nervous. What Is a Somatosensory Evoked Potential (SEP) Test? Collection Instructions: Label specimen as spinal fluid. However, the target specificities of the IgG in MS OCBs have remained undiscovered. Have you found anything out yet? Examining CSF and serum in parallel for OCBs of IgG provides more diagnostic information than examining CSF alone, and the latter is potentially misleading. A doctor may use a CSF oligoclonal banding test to help confirm a diagnosis of MS. PMC Gurtner KM, Shosha E, Bryant SC, Andreguetto BD, Murray DL, Pittock SJ, Willrich MAV. Unconcentrated CSF and diluted serum are electrophoresed by isoelectric focusing.

WebEvaluation of these oligoclonal bands have centred on disease-specific conditions such as multiple sclerosis and a range of inflammatory conditions, often emphasizing the intrathecal production. Dr. Clardy has received personal compensation for serving as an employee of Veterans Health Administration (VHA). Online ISSN:1526-632X, The most widely read and highly cited peer-reviewed neurology journal, Matched or Unique Cerebrospinal Fluid Oligoclonal Bands: Clinical Characteristics and Diagnostic Utility (S3.009). If the test comes back positive for OCB levels, but a doctor cannot diagnose MS, they will likely order further testing to determine the underlying cause of the elevated OCB levels. Thompson AJ, Banwell BL, Barkhof F, et al: Diagnosis of multiple sclerosis: 2017 revisions of the McDonald criteria. WebIn order to confirm local production of oligoclonal IgG in CSF, a matched serum sample is required. Oligoclonal Banding, Serum and Cerebrospinal Fluid However, as the National Multiple Sclerosis Foundation states, test scores are not enough to confirm a diagnosis. The assay uses reagents from Helena Laboratories. Bookshelf Last medically reviewed on March 18, 2022. The CSF oligoclonal band screen looks for these bands in your CSF.

WebWhen the oligoclonal band assay detects 2 or more unique IgG bands in the cerebrospinal fluid (CSF), the result is positive. They will remove the needle and apply a dressing. When the oligoclonal band assay detects 2 or more unique IgG bands in the cerebrospinal fluid (CSF), the result is positive. Cerebrospinal fluid (CSF) analysis at the time of diagnosis is used for investigation of CSF pathology and for differential diagnosis work up. Increased intrathecal Ig synthesis may occur in other inflammatory CSF diseases and, therefore this assay is not specific for MS. CSF Oligoclonal Bands Interpretation: <2 bands.
