Because of the low incidence of neonatal meningitis, few studies have been done on the CRP rises in neonatal meningitis, and those done have small numbers: the sensitivity of a CRP > 10mg/L cut-off has been suggested to be 76.3% in one study, [23] and a CRP > 40mg/L to be 72.7% at 24h [24]. The gene discussed is CRP; the disease is infectious meningitis.
