- Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of the C-reactive protein (CRP) level (cut-off ≥50 mg/l), white blood cell (WBC) count (cut-off < 4.0 × 109/l or > 12.0 × 109/l), neutrophil count (cut-off > 10.0 × 109/l), lymphocyte count (cut off < 1.0 × 109/l) and the neutrophil-lymphocyte count ratio (NLCR) (cut-off > 10.0) in diagnosing bacteremia.
