Answer

Children with neurological signs should have their cerebrospinal fluid (CSF) examined. The CSF of patients with varicella encephalitis may have few or as many as 100 cells that are polymorphonuclear or mononuclear, depending on the timing of the lumbar puncture. Glucose levels are within the reference range. Protein levels are within the reference range or are slightly elevated.
