Abstract
|
|
|
The real-time polymerase chain reaction (real-time RT-PCR) assay is currently used as a confirmatory test for the detection of coronavirus disease 2019 (COVID-19) since the disease is in community transmission stage in South Korea.
However, the Ministry of Food and Drug Safety recently conditionally approved the COVID-19 self-test kit (which is a rapid severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2] antigen detection assay), as an additional testing method. The rapid SARS-CoV-2 antigen detection test is difficult to use as a diagnostic tool or screening assay because of the high probability of false-negative results, as it has a lower sensitivity than the RT-PCR assay. However, it can be used as an adjunctive method because of high specificity and faster results. Considering the high specificity of the selftest kit, it is necessary to assume and treat COVID-19 self-test kit positive patients as confirmed COVID-19 patients.
Therefore, emergency departments, pre-hospital caregivers and 119 rescuers should prepare a protocol with quarantined spaces and protective equipment for treating COVID-19 self-test kit positive patients, to prevent the spread of infection.
