Lumbar puncture is the single most specific test to confirm the diagnosis of bacterial meningitis. It is indicated in all patients with suspicion of bacterial meningitis unless there is a contraindication. The CSF findings in patients with bacterial meningitis include low glucose concentration, high protein content, increased no of granulocytes and lactate levels >2.1mmol/l.
