OLIGOB
Example Reports
Abnormal
Normal

Ordering Recommendation

May be used in the assessment of multiple sclerosis to detect unique IgG oligoclonal bands in cerebrospinal fluid (CSF) in conjunction with a matched serum specimen. The preferred test to assess for multiple sclerosis is Oligoclonal Band Profile (0080440).

New York DOH Approval Status

This test is New York state approved.

Specimen Required

Patient Preparation
Collect

CSF AND serum separator tube or plain red.

Specimen Preparation

Allow serum to clot completely at room temperature. Separate serum from cells ASAP or within 2 hours of collection. Transport two specimens. Transfer 1.5 mL CSF to an ARUP standard transport tube (Min: 0.7 mL) AND transfer 1 mL serum to an ARUP standard transport tube. (Min: 0.6  mL).

Storage/Transport Temperature

Refrigerated.

Unacceptable Conditions

Grossly bloody or hemolyzed specimens or severe lipemia

Remarks

Recommendation is for CSF and serum to be collected within 24 hours of each other. Specimens collected outside this timeframe will be accepted at ordering provider's discretion.

Interpretive Data

To ensure accurate result interpretation, it is recommended that both CSF and serum specimens be collected on the same day. If specimens are not collected within this specified timeframe, it is advised to exercise caution when interpreting the results.

Compliance Category

FDA

Note

Specimens must be assayed together for interpretation.
This test reports only the number of oligoclonal bands; 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.
