OLIGOCLONAL BANDING SERUM/CSF

LAB740

 

Collect

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)

Storage/Transport Temperature

Refrigerated.

Stability (from collection to initiation)

Ambient: 8 hours; Refrigerated: 1 week; Frozen: 1 year

Notes

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.

Performed

Sun-Sat

Methodology

Qualitative Isoelectric Focusing/Electrophoresis/Nephelometry

Reported

1-3 days

Synonyms

  • LAB740
  • OLIGOCBAND

Ordering Recommendations

Preferred CSF test for the workup of suspected multiple sclerosis. Detects IgG oligoclonal bands in CSF and calculates the CSF IgG index.
