Oligoclonal Band Profile Oligoclonal Band Profile ARUP Test Link Mnemonic OLIGO Synonym CSF Oligoclonal Bands - MS Panel - MS Profile - Multiple Sclerosis Panel - Multiple Sclerosis Panel without Myelin Basic Protein - Multiple Sclerosis Profile - Oligoclonal Banding - IgG Index - IgG Synthesis Rate - MS - Isoelectric Focusing - IEF Includes CSF Oligoclonal Bands, CSF & Serum IgG, CSF & Serum Albumin, IgG Index, CSF IgG Synthesis Rate, Albumin Index, CSF IgG/Albumin Ratio, Interpretation Guidelines Preferred test in the workup of multiple sclerosis. Detect unique IgG oligoclonal bands in cerebrospinal fluid (CSF) in conjunction with a matched serum specimen. Calculate CSF IgG index. Specimen Collection Requirements Collect Serum AND CSF, one 5.0 mL gold (SST) or 7.0 mL red top tube AND 1.5 mL CSF in a sterile container. IMPORTANT: Serum must be collected within 48 hours of CSF collection. Handling Allow serum to clot completely at room temperature (minimum: SST – 30 minutes and red top tubes – 60 minutes). Centrifuge and separate serum from red and white cells within 2 hours of collection. Transfer serum and CSF to two separate ARUP Standard Transport Tubes. Preferred Volume 1.0 mL Serum; 1.5 mL CSF Minimum Volume 0.5 mL Serum; 0.7 mL CSF Transport Refrigerated (2-8°C) Rejection Criteria Grossly hemolyzed specimens, plasma specimens and specimens collected outside the 48 hour window. Stability SERUM (AFTER SEPARATION FROM CELLS): Room Temperature (18-26 °C): 8 hours; Refrigerated (2-8 °C): 7 days; Frozen (≤ -20 °C): 1 year CSF: Room Temperature (18-26 °C): 8 hours; Refrigerated (2-8 °C): 7 days; Frozen (≤ -20 °C): 1 year Testing Information Note Specimens must be assayed together for interpretation. Performed 7 days per week Reported 2-4 days Method Isoelectric Focusing, Electrophoresis, Nephelometry Referral Lab ARUP (0080440) Reference Values Reference Values Professional interpretation provided by ARUP Laboratories. Comments A patient is considered positive for CSF oligoclonal bands if there are two or more bands in the CSF immunoglobulin region that are not present in the serum. In order to confirm local production of oligoclonal IgG in CSF, a matched serum sample is required. Oligoclonal bands present in CSF, but not in serum, indicate central nervous system production. Oligoclonal bands are performed using isoelectric focusing and immunofixation.
