Patients with IE due to an infection with Staphylococcus aureus compared to other pathogens (Figure 4) showed no significant differences in values of PCT (2.1 [0.9 – 2.1] vs. 0.5 [0.2 – 2.1] ng/mL, p = 0.36), CRP (169 [48 – 230] vs. 86 [33 – 163] mg/L, p = 0.11) and WBC (11.7 [10.6 – 15.9] vs. 10.1 [7.2 – 13.4] G/L, p = 0.28). This evidence concerns the gene CRP and infection.
