A doctor will need to conduct additional testing to determine the presence of MS. To test OCB levels, a doctor will need to perform a CSF oligoclonal banding test, which involves inserting a needle into the spine to collect CSF. The oligoclonal band pattern is blurred when a concomitant inflammatory response causes increased protein leakage of plasma proteins into the CSF. Cavuoti D, Baskin L, Jialal I. Acta Neurol Scand. Spasticity is a common symptom of multiple sclerosis. In some cases, all the lanes are homogeneously darkened to the same degree. Oligoclonal bands are visible as an increased concentration of restricted bands of IgG after isoelectric focusing and immunofixation of IgG. Background Meningoencephalitis of unknown origin (MUO) is an inflammatory disease of the canine central nervous system (CNS) that shares several features with multiple sclerosis (MS) in humans.
