ABSTRACT
Introduction: Health care workers (HCWs) are a high-risk group for SARS-CoV-2 infection, therefore there is an urgent need for rapid, simple, and sensitive tests to diagnose COVID-19 infection among health care settings. Aim(s): The aim of our study was to assess the contribution of the SARS-CoV-2 antigen rapid diagnostic tests (AgRDTs) with RT-PCR which is the gold standard for the diagnosis of COVID-19. Method(s): A retrospective descriptive study of HCWs at Charles Nicolle Hospital who consulted the Occupational Medicine health Department during the period from January 3, 2022, to January 31, 2022, for symptoms suggestive of COVID-19 infection. The Panbio antigen rapid diagnostic tests were used in all suspected cases. In case of negative Ag-RDTs, we completed with RT-PCR. Result(s): Our population consisted mainly of nurses (n=146), blue-collar workers (n=100), trainees (n=105) and senior technicians (n=84). We performed 638 Ag-RDTs and 177 RT-PCR during the study period. Ag-RDTs were positive in 461 cases (72.25%). 146 HCPs tested negative by both methods. Discordant results were obtained in 31 cases (17.51%). RT-PCR was positive in 31 cases. Conclusion(s): In our series, the Ag -RDT seems a reliable way for the diagnosis of covid 19 in symptomatic HCWs.
