Test Overview
Quantitative Enzyme-Linked Immunoassay
The most common indication for ordering the MBP test is in the differential diagnosis of Multiple Sclerosis (MS). Elevated concentrations of MBP in the CSF is only an indication of demyelination, which can occur in clinical contexts other than MS. Therefore, elevated concentration of MBP in the CSF should not be considered as a diagnostic marker for MS. Recent revisions to the diagnostic criteria for MS include CSF oligoclonal IgG bands and/or increased IgG index, but not MBP measurements.

Specimen Requirements
Place CSF in a clean plastic screw capped tube or container and freeze.
Additional Information
Hemolysis is associated with falsely-elevated levels of MBP in the cerebrospinal fluid. CSF should be free from contamination with blood, if possible. If all available CSF is bloody, centrifuge the sample and separate supernatant from cells prior to freezing the sample. Test sent to ARUP Laboratories.
