The name for the bands of bunched-together antibodies suggesting MS activity.
People with MS typically have a higher level of antibodies than others, so this can be used as a way to diagnose the condition. You may be asked to have a lumbar puncture to take a sample of spinal fluid, which is then tested to see if this is the case. If the test shows two or more visible ‘bands’ of bunched-together antibodies, known as 'oligoclonal bands', this suggests the presence of disease activity. This occurs in around 80-95% of people with Multiple Sclerosis.
