PPV: positive predictive value. NPV: negative predictive value. WBC: white blood count. CRP: C-reactive protein. I/T ratio: immature-to-total-neutrophil ratio. N.B. Cut-off value: total neutrophil count < 4.0 or > 25.0 103/mm3; platelet count < 50.0 or > 500.0103/mm3 ; I/T ratio > 0.2; CRP >10 mg/dL; serum calprotectin >1.7 μg/mL [8–10, 12, 16]. |
