Question

csf lactate is elevated in patients with viral meningitis but not in patients with bacterial meningitis.
true
false

Explanation:

In bacterial meningitis, CSF lactate is elevated due to bacterial metabolism and impaired cerebral oxidative metabolism. In viral meningitis, the blood - brain barrier is less disrupted, and there is no significant anaerobic metabolism to cause a marked elevation of CSF lactate. So the statement "CSF lactate is elevated in patients with viral meningitis but not in patients with bacterial meningitis" is incorrect.

Answer:

B. False
