CSF analysis shows: glucose 36 mg/dL, protein 110 mg/dL, and WBCs (PMNs) 1,000/microliters.

Classic CSF findings inbacterial meningitis:

Low glucose(<40 mg/dL) – due to bacterial consumption

High protein(>100 mg/dL) – from inflammation and blood-brain barrier disruption

High WBCs, particularlypolymorphonuclear cells(>1000/microliter) – indicating a strong immune response

These values are not consistent with viral meningitis or autoimmune disorders like Guillain-Barré.

“In bacterial meningitis, CSF typically reveals hypoglycorrhachia, elevated protein, and a predominance of neutrophilic leukocytosis.”
