CRP and bacterial infectious disease: C-reactive protein (CRP), WBC count, and neutrophil percentage are commonly used inflammatory biomarkers in blood but there is no consensus about their ability to distinguish between bacterial or viral pathogens.[11] Previous studies have reported a possible correlation between an increased serum CRP level and a bacterial CNS infection.[13,14] No correlation between an increased WBC count or neutrophil percentage and a bacterial infection has previously been reported.[15] No data on the specificity of these blood biomarkers in the context of neonatal CNS infection were available.
