CSF oligoclonal banding is a test to look for inflammation-related proteins in the cerebrospinal fluid (CSF), the clear fluid that flows in the space surrounding the spinal cord and brain.

Oligoclonal bands are proteins called immunoglobulins, which suggest inflammation of the central nervous system. The presence of oligoclonal bands may be a sign of multiple sclerosis.

Cerebrospinal fluid - immunofixation

A sample of CSF is needed. A lumbar puncture (spinal tap) is the most common way to collect this sample. For information on this procedure, see the article on lumbar puncture.

Other methods for collecting CSF are rarely used, by may be recommended in some cases. They include:

• Cisternal puncture
• Ventricular puncture
• Removal of CSF from a tube that is already in the CSF, such as a shunt or ventricular drain.

After the sample is taken, it is sent to a laboratory for evaluation.

This test helps support, but does not confirm, the diagnosis of multiple sclerosis (MS). The presence of oligoclonal bands in the CSF can also be seen in other illnesses.
