In approximately 95% of MS patients, two immunoglobulin G (IgG) oligoclonal bands (OCBs) are detectable exclusively in the cerebrospinal fluid (CSF). 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). Typically, the monoclonal protein is discovered, and workup then ensues. Diagnoses in the second group of patients, with unique CSF OCBs in addition to serum OCBs, resembled those among patients with CSF OCBs alone.
