SARS-CoV-2 rapid antigen-detecting tests (Ag-RDTs) can be considered complementary to RT-PCR for rapid testing, or as an alternative for RT-PCR in settings where resources and laboratory infrastructure are limited as suggested by the WHO. Also, the longer turn-around time for results from laboratory-based RT-PCR testing does not allow for rapid decision-making, often taking days until results are available, thus identifying infected individuals is often too late to prevent secondary cases. Because RT-PCR testing requires advanced laboratory infrastructure demanding numerous predefined materials and specially trained staff, testing capacities in many countries have at times been pushed to their limits. Reverse transcriptase polymerase chain reaction (RT-PCR) has been established as the gold standard for diagnosing individuals infected with SARS-CoV-2. The SARS-CoV-2 pandemic has caused over 100В million confirmed infections worldwide, stated by the World Health Organization (WHO).

Trial registration number and registration date The LumiraDxв„ў assay showed excellent analytical sensitivity, exclusivity and clinical specificity with good clinical sensitivity using supervised NMT self-sampling. The ease-of-use-assessment was favourable for lower throughput settings. Testing against common respiratory commensals and pathogens showed no cross-reactivity and LOD was estimated to be 2вЂ“56 PFU/mL. Sensitivity was increased in individuals with viral loadвЂ‰в‰ҐвЂ‰7 log10 SARS-CoV2 RNA copies/ml (93.8% CI 86.2вЂ“97.3%). 120 out of 146 RT-PCR positive cases were detected positive by LumiraDxв„ў, resulting in a sensitivity of 82.2% (95% CI 75.2вЂ“87.5%). 761 participants were enrolled, with 486 participants reporting symptoms on testing day. The study was conducted between November 2nd 2020 and 4th of December 2020. An analytical study assessed exclusivity and limit-of-detection (LOD). Sub-analyses investigated the results by viral load, symptom presence and duration.

Results were compared to calculate sensitivity and specificity. Participants collected a supervised nasal mid-turbinate (NMT) self-swab for Ag-RDT testing, in addition to a professionally collected nasopharyngeal (NP) swab for routine testing with reverse transcriptase polymerase chain reaction (RT-PCR).

This multi-centre diagnostic accuracy study investigated performance of the microfluidic immunofluorescence LumiraDxв„ў assay, enrolling symptomatic and asymptomatic participants with suspected SARS-CoV-2 infection. Conceivably, microfluidic immunofluorescence Ag-RDTs could increase sensitivity for SARS-CoV-2 detection. Thus far, sensitivity (в‰¤вЂ‰85%) of lateral-flow assays has limited scale-up. Rapid antigen-detecting tests (Ag-RDTs) for severe acute respiratory syndrome coronavirus 2 ( SARS-CoV-2) can transform pandemic control.
