What will CSF show in viral meningitis?
CSF Glucose and Protein The CSF glucose level is usually within the reference range in viral meningitis, but it may be low in some cases of LCM, HSV, mumps virus, or poliovirus infection. The CSF protein level (reference range, 20-50 mg/dL) is usually elevated in bacterial meningitis.
What is the best CSF test that would differentiate bacterial from viral meningitis?
Therefore the charac- teristics of cerebrospinal fluid (CSF) have been used to differentiate between bacterial and viral meningitis [7, 8].
What are the CSF findings in bacterial meningitis?
A CSF:blood glucose level of < 50% suggests possible meningitis. A CSF glucose level of ≤ 18 mg/dL or a CSF:blood glucose ratio of < 0.23 strongly suggests bacterial meningitis. However, changes in CSF glucose may lag 30 to 120 minutes behind changes in blood glucose.
How can you tell the difference between a bacterial and viral infection?
Bacterial Infections Symptoms persist longer than the expected 10-14 days a virus tends to last. Fever is higher than one might typically expect from a virus. Fever gets worse a few days into the illness rather than improving.

Is meningitis a bacterial or viral infection?
Is viral or bacterial meningitis contagious?
