The stability of the CSF sample varies depending on the procedures ordered.

Cell counts are ALWAYS STAT and should be performed within 30 - 60 minutes for best results.

Samples should be left at room temperature for no longer than one hour and refrigerated following testing.

Refrigeration is not recommended for culture specimens since fastidious organisms such as Haemophilus influenzae and Neisseria meningitidis may not survive the cold temperature.
