Diagnostic accuracy of neutrophils expressing CD11c, CD64 and of plasma C-reactive protein (CRP) levels for sepsis. Receiver operator characteristic (ROC) curves are presented for (a) CD11c⁺ neutrophils (b) CD64⁺ neutrophils and (c) plasma CRP levels. In differentiating patients with sepsis from those with N-I systemic inflammatory response syndrome (SIRS), sepsis was defined as either positive microbiology or a strong clinical suspicion. Sensitivity and specificity values are shown together with optimal cut-off points, the areas under curve (AUC) and likelihood ratios (LR).
