WitrynaNAATs are the most sensitive class of tests available, and this method will help to ensure that cases are not missed among symptomatic patients [Citation 26, Citation 67]. In this context, RT-PCR testing and TMA are appropriate compared with LAMP, as sensitivity data are still variable (Table 1) [Citation 17–20, Citation 23, Citation 68–70]. WitrynaPCR tests by nasopharyngeal swab have a sensitivity of 73%, but systematic analysis of specificity has not been determined due to the lack of PCR studies with a control group.
