===Cerebrospinal fluid (lumbar puncture)===
Testing of cerebrospinal fluid obtained from a [[lumbar puncture]] can provide evidence of chronic inflammation in the central nervous system. The cerebrospinal fluid is tested for [[oligoclonal band]]s of IgG on [[electrophoresis]], which are inflammation markers found in 75–85% of people with MS.<ref name="pmid11456302" /><ref name="pmid16945427">{{cite journal | vauthors = Link H, Huang YM | title = Oligoclonal bands in multiple sclerosis cerebrospinal fluid: an update on methodology and clinical usefulness | journal = Journal of Neuroimmunology | volume = 180 | issue = 1–2 | pages = 17–28 | date = November 2006 | pmid = 16945427 | doi = 10.1016/j.jneuroim.2006.07.006 | s2cid = 22724352 }}</ref>
