Quest Code
7085
CPT Codes
82040, 82042, 82784 (x2), 83873, 83916
Includes
Myelin Basic Protein, Oligoclonal Bands (IgG), CSF, and IgG Synthesis Rate/Index, CSF
Preferred Specimen
4.2 mL CSF collected in a CSF collection tube #4 and 3 mL serum
Minimum Volume
2 mL CSF and 1.5 mL serum
Instructions
Please see the individual tests for specific specimen requirements and stabilities.
For the Oligoclonal Bands and IgG Synthesis Rate assays, both CSF & Serum are required specimens. It is preferred that the collection date and time be the same for both; however, it is acceptable for them to be drawn within 48 hours of each other. If no serum is supplied, the client will be contacted to confirm the order.
CSF collection tube #4 is preferred. Submitting 4th lumbar puncture collection tube minimizes blood contamination.
Transport temperature: Refrigerate CSF specimens at 2-8°C in sterile, plastic CSF vial(s) and send refrigerated (cold packs) to the laboratory OR freeze CSF specimens at -20°C and send frozen samples to the laboratory on dry ice.
