Do lumbar puncture results suggest meningitis1?

1. Results suggestive of meningitis:

  • In neonates (under 28 days old), 20 cells/μl or higher.
  • In older children over 5 cells/μl or over 1 neutrophil/μl 
  • if lower cell count, still consider bacterial meningitis if other symptoms and signs suggest the diagnosis especially in neonates.
