Diagnostic accuracy of C-reactive protein and procalcitonin in suspected community-acquired pneumonia adults visiting emergency department and having a systematic thoracic CT scan

Abstract

Key messages * The predictive value of clinical symptoms in identifying CAP patients is poor * No CRP or PCT cut-off value is sufficiently discriminating to confirm or refute CAP diagnosis with a high level of certainty * The diagnostic accuracy of biomarkers was not improved when CAP cases considered as viral were excluded from analysis.
