CRP and ventilator-associated pneumonia: Studies by our group showed that on the day of confirmed VAP, both CRP and PCT levels could be useful.(21,22) Recently, we showed that among patients with documented VA-LRTI, the levels of CRP and PCT were significantly higher in VAP patients than in VAT patients.(23) Moreover, we found that CRP and PCT concentrations in confirmed VAT patients were 14mg/dL and 0,64ng/mL (median), respectively.
