CSF oligoclonal banding
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.
- Alternative Names
Cerebrospinal fluid - immunofixation
- How the test is performed
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.
- How to prepare for the test
- How the test will feel
- Why the test is performed
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.
- Normal Values
Normally, one or no bands should be found in the CSF.
Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
- What abnormal results mean
There are two or more bandings found in the CSF and not in the blood. This may be a sign of multiple sclerosis or other inflammatory processes.
