OMG, you are so describing me. Have you found anything out yet? I've been dealing with this now for 2 years with no answers and countless tests. Increased IgG production by the central nervous system is not specific for multiple sclerosis, but is an indication of chronic neural inflammation. The doctor or nurse will then perform the following steps: Lab technicians will then analyze the CSF sample for OCBs. The diagnostic process will also involve the doctor: If elevated OCB levels are present but a person does not fit the criteria for MS, a doctor will likely continue to search for the underlying cause. The test alone is not enough to diagnose MS. A doctor must also find: The CSF oligoclonal banding screening involves undergoing a procedure called a lumbar puncture. Isoelectric focusing (IEF) on agarose gels followed by immunoblotting is the technique recommended for OCB detection, analyzing paired undiluted CSF and serum samples. Author Lone Frank talks about Dr. Robert Heath, who was hailed a pioneer and criticized as an exploiter during his career. Examining CSF and serum in parallel for OCBs of IgG provides more diagnostic information than examining CSF alone, and the latter is potentially misleading.
