Bacteria consume glucose, so the level falls; inflammation raises the protein; and acute bacterial infection produces a neutrophil predominance. Viral meningitis typically shows a normal glucose with lymphocytic predominance. Tabulating these three parameters resolves nearly all differential questions.
