Measurement of CSF protein is used to distinguish septic from aseptic meningitis and is also associated with increased permeability of the blood:brain barrier, vasogenic brain oedema, hypercellularity and release of brain-specific proteins during cell death.
Protein concentrations >1 g/L are often viewed as diagnostic for bacterial, fungal or tuberculous meningitis.
