Which of the following laboratory findings are consistent with acute bacterial meningitis

Which of the following laboratory findings are consistent with acute bacterial meningitis? (Select all that apply)

A. Cerebrospinal fluid (CSF) with elevated white blood cell (WBC) count (neutrophil-predominant)

B. CSF with low glucose level

C. CSF with high protein level

D. CSF with normal pressure
