Real-time RT-PCR in COVID-19 detection: issues affecting the results. A case presentation for positive SARS-CoV-2 RNA recurrence in a patient with a history of type 2 diabetes that had recovered from severe COVID-19. ![]() Validation and verification of the Abbott RealTime SARS-CoV-2 assay analytical and clinical performance. These data indicate that the BinaxNOW COVID-19 Ag card has an analytical sensitivity approximately equivalent to a generic qRT-PCR cycle threshold ( C T ) value of 29 to 30.Ībbott BinaxNOW COVID-19 SARS-CoV-2 coronavirus limit of detection rapid antigen detection sensitivity.Ĭopyright © 2021 American Society for Microbiology.ĭegli-Angeli E, Dragavon J, Huang M-L, Lucic D, Cloherty G, Jerome KR, Greninger AL, Coombs RW. One hundred percent of samples with viral loads of >40,000 copies/swab were detected by rapid antigen testing. We further confirmed this limit of detection with 72 additional clinical samples positive for SARS-CoV-2 in either phosphate-buffered saline or viral transport medium. Initial and confirmatory limits of detection for the BinaxNOW COVID-19 Ag card were determined to be equivalent to 4.04 × 10 4 to 8.06 × 10 4 copies/swab. Here, we evaluated the analytical sensitivity of the Abbott BinaxNOW COVID-19 Ag card using SARS-CoV-2-positive clinical specimens quantified by reverse transcription-droplet digital PCR (RT-ddPCR) and multiple FDA EUA qRT-PCR platforms using RNA standards. Robust analytical sensitivity data in comparison to reverse transcription-quantitative PCR (qRT-PCR) are currently lacking for many rapid antigen tests. Although less sensitive than molecular detection methods, rapid antigen testing offers the potential for inexpensive, quick, decentralized testing.
