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). After the test, you may notice a bruise at the needle insertion site - it will subside on its own in a few days. What Is a Somatosensory Evoked Potential (SEP) Test? If there are two or more oligoclonal bands present in your CSF with no corresponding bands in the serum, the result is considered positive. The speed of movement is dictated by their charge. Hereditary spastic paraparesis. Finally, when several bands with sharp borders are seen after immunofixation in cerebrospinal fluid (CSF) but not in serum, the result is reported as positive for oligoclonal bands. The presence of no oligoclonal bands or one band is normal.

Management of clinically and radiologically isolated syndromes suggestive of multiple sclerosis. 1. 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.
