Myelin Basic Protein Test on Spinal Fluid

Rhode Island rates for HCPCS 83873

This laboratory test measures myelin basic protein, a component of the protective coating around nerve fibers, in a sample of cerebrospinal fluid taken from around the brain and spinal cord. Elevated levels can indicate ongoing damage to that protective coating, which happens in conditions such as multiple sclerosis or other disorders that injure the nervous system. It is used alongside other tests and clinical findings rather than as a stand-alone diagnosis.
