Specimen Handling

Collection Instructions: Collect CSF and a minimum of 1 mL serum. It is essential for interpretation of results to submit both specimens at the same time, but a serum sample of +/- 21 days of the spinal tap is acceptable as long as no treatment was started. Analyze specimens fresh whenever possible

Laboratory Staff Instructions: Enter date and time collection in the LIS. Specify sample number in order comment.
