Laboratory Handling
Phlebotomy
2.0 mL is the recommended volume; a minimum of 0.6 mL of CSF is required, but this is insufficient for a duplicate analysis (recommended).
Transport
Only applies to samples collected at AKH. Send on ice within 5 minutes to the laboratory. Please arrange with the laboratory prior to sending the specimen.
