Diagnostic accuracy of SARS-CoV-2 saliva antigen testing in a real-life clinical setting

•SARS-CoV-2 saliva antigen tests facilitate testing with poorly trained personnel•Their diagnostic accuracy in clinical settings is essentially unclear•We conducted a diagnostic accuracy study in a real-life clinical setting•The diagnostic accuracy of the PCL saliva antigen test was 30.2%•Application of the test might lead to a large number of false-negative test results
