Interpretive Data
Note
CSF electrophoresis may be useful in the diagnosis of tumors in the central nervous system or neurological illness. Oligoclonal Band Profile (ARUP test code 0080440) or Myelin Basic Protein (ARUP test code 0080515) may be more appropriate for patients with suspected multiple sclerosis. For the evaluation of blood brain barrier integrity, Immunoglobulin G, CSF Index (ARUP test code 0050676), included in the Oligoclonal Band Profile test, may be useful.
