CRP and Neonatal sepsis: Additionally, Song et al. [41] conducted a meta-analysis concerning the diagnostic value of nCD64 combined with CRP for neonatal sepsis, and they reported that the combined application of CD64 and CRP improved the accuracy of neonatal sepsis diagnosis with a sensitivity of 0.95 (95% CI: 0.86–0.98) and specificity of 0.86 (95% CI: 0.74–0.93), respectively.
