Clinical chorioamnionitis was diagnosed by Gibbs et al. when maternal temperature was elevated (>38 °C), and two or more of the following criteria were presented: maternal (>100 beats/min) or fetal (>160 beats/min) tachycardia, uterine tenderness, foul-smelling amniotic fluid, elevated white blood cell (WBC > 15,000/mm3) count, and maternal plasma C-reactive protein (CRP) > 10 mg/L [6]. Here, CRP is linked to chorioamnionitis.
