Ordering Recommendation

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.

New York DOH Approval Status
This test is New York DOH approved.
Specimen Required
Patient Preparation

CSF AND serum separator tube or plain red. Serum specimen should be drawn within 48 hours of CSF collection.

Specimen Preparation

Allow serum to clot completely at room temperature. Separate serum from cells ASAP or within 2 hours of collection. Transport 1.5 mL CSF. (Min: 0.7 mL) AND transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.5 mL)

Interpretive Data

No compliance statements are in use for this test.


Specimens must be assayed together for interpretation.
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.
