In this study, we evaluated the performance of a commercial rapid syndromic multiplex PCR panel on OP samples and high-quality LRT samples obtained from a well-characterized cohort of patients presenting to the ED with CAP. The PCR panel is validated for LRT samples, which can be difficult and time-consuming to obtain, especially in an ED setting. We demonstrated high NPAs and PPAs between OP- and high-quality LRT samples for the most common bacterial pathogens involved in CAP. To our knowledge, this study is the first to evaluate syndromic PCR testing on OP samples from CAP patients.In previous CAP studies, an LRT sample has been obtained from only 30%–60% of the included patients, often after transfer from the ED (Pneumonia is a heterogeneous condition, with differences in microbiological etiology. The FAP Most divergent results between OP- and LRT samples were caused by detections of various Enterobacterales, which are of uncertain clinical importance in uncomplicated CAP (The strengths of this study include a well-characterized study population with a CAP diagnosis based on predefined criteria, and the use of the FAP In conclusion, our study demonstrated that the FAP
