Abstrakt: Oligoclonal bands (OCBs) represent the presence of intrathecal immunoglobulin G (IgG) as detected by isoelectric focusing and immunofixation. Cerebrospinal fluid (CSF) analysed alongside a paired serum sample gives five different immunofixation patterns. These are: type 1--the normal physiological state with no intrathecal IgG synthesis; type 2--evidence for intrathecal IgG synthesis, with CSF- restricted OCBs; type 3--evidence for intrathecal IgG synthesis, with CSF- restricted OCBs, but with additional, identical bands in the CSF and serum; type 4--absence of intrathecal IgG synthesis, but with identical OCBs in CSF and serum; and type 5--absence of intrathecal IgG synthesis, with a monoclonal band in CSF and serum. Analysis of these patterns can help to diagnose a range of neurological conditions, including multiple sclerosis. However, it is important to interpret OCB results alongside other CSF tests and their clinical context. [ABSTRACT FROM AUTHOR]
