Among 161 patients in whom both serum and urine demonstrated positive results for monoclonal protein and who were, posttreatment, negative for serum immunofixation, just 3 (1.9%) displayed positive urine immunofixation. Oligoclonal bands (OCBs) are bands of immunoglobulins that are seen when a patient's blood serum, or cerebrospinal fluid (CSF) is analyzed. Local CNS synthesis implies local CNS disease, especially multiple sclerosis but sometimes other CNS inflammation, infection or neoplasia. In: Burtis CA, Bruns DE, eds. Increased intrathecal Ig synthesis may occur in other inflammatory CSF diseases and, therefore this assay is not specific for MS. You will be made to wear a hospital gown with an open back.

However, they should let the doctor know about any medications they are taking, including blood thinners, and any medical history that relates to their spine. Examining CSF and serum in parallel for OCBs of IgG provides more diagnostic information than examining CSF alone, and the latter is potentially misleading. These technical issues can lead to difficulties in distinguishing between negative results (type 1 pattern = absence of OCBs in serum and CSF and type 4 pattern = presence of identical OCBs in both serum and CSF) and results indicating intrathecal IgG synthesis (pattern 2 = presence of OCBs in CSF and type 3 = presence of OCBs in CSF and additional identical OCBs in both serum and CSF).
