If they find that a person has MS, they will work with the individual to develop a treatment plan based on their particular needs. Two or more oligoclonal IgG bands (OB) detected by separation of cerebrospinal fluid (CSF) proteins while not demonstrable in corresponding serum reflect a local B-cell response accompanying central nervous system (CNS) inflammation. Lin MW, Suan D, Lenton K, Henniker T, Burke T, Vucic S, Fulcher DA. Next, theyll apply a local anesthetic.

Abnormal CSF OCB patterns have been reported in 70% to 80% of MS patients. The person conducting the test will clean your back with antiseptic. Only a small number of oligoclonal IgG bands in 7 of 10 CSF and serum pairs had identical isoelectric points and the same type of L chain. Tiu VE, Popescu BO, Enache II, Tiu C, Terecoasa E, Panea CA. 1. Therefore, the International Myeloma Working Group Mass Spectrometry Committee created a set of recommendations for the evaluation of monoclonal proteins in multiple myeloma and related disorders, using mass spectrometry.
