Bookshelf This sample is often difficult to collect, and suboptimal collection might alter the result. Diagnoses in the second group of patients, with unique CSF OCBs in addition to serum OCBs, resembled those among patients with CSF OCBs alone. Immunofixation in CSF for the detection of oligoclonal bands is indicated every time there is suspicion for multiple sclerosis. [18, 19], Detection of a paraprotein by immunofixation is possible in lymphomas. A doctor will insert a needle through the skin and into the spine. They will insert the thin needle between the two bones in the lower back and extract the sample. If the monoclonal protein level decreases or is undetectable after chemotherapy, it might indicate a response to treatment. [QxMD MEDLINE Link]. 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).
