Procalcitonin as a Biomarker for a Bacterial Infection on Hospital Admission: A Critical Appraisal in a Cohort of Travellers with Fever after a Stay in (Sub)tropics

Figure 3

Receiver operating characteristic (ROC) curves of procalcitonin (PCT) and C-reactive protein (CRP) testing on admission for a confirmed bacterial cause of fever in 157 travellers who returned home with fever after a stay in the (sub)tropics. The respective cutoff points for CRP were 300, 250, 150, 100, and 50 mg/L, respectively, and the cutoff points for PCT were 10, 2, and 0.5 ng/mL, respectively.
