This study aimed to assess the diagnostic impact of POC-PCR testing in patients with suspected community-acquired pneumonia (CAP) in the ED. This study is a secondary analysis of a Danish multicenter randomized controlled trial (RCT) that included patients aged \u226518 years admitted to the ED between March 2021 and February 2022. In the primary trial, patients were randomly assigned to one of two parallel groups: (i) intervention group: POC-PCR in addition to standard care, or (ii) control group: standard care only (SCO). The present secondary analysis focuses exclusively on patients in the intervention group, where both POC-PCR and standard culture-based diagnostics were performed. The diagnosis of CAP was determined by an expert panel. In the intervention group, 145 patients had a lower respiratory tract (LRT) specimens analyzed using both POC-PCR and culture. POC-PCR identified notably more microorganisms compared with culture (187 vs 34). The agreement between positive results obtained by POC-PCR and culture was 6 of 19 (31.6%) for\n                      <jats:italic toggle=\"yes\">Streptococcus pneumoniae<\/jats:italic>\n                      and 16 of 61 (26%) for\n                      <jats:italic toggle=\"yes\">Haemophilus influenzae<\/jats:italic>\n                      .
