Preferred Specimen
2 mL CSF in a sterile screw cap container and 1 mL serum
Minimum Volume
1 mL CSF and 0.5 mL serum
Instructions
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.
