Title: Reverse transcription recombinase-aided amplification assay for rapid detection of the influenza A(H1N1)pdm09 H275Y mutation that confers oseltamivir resistance Cord-id: 6p97bk81 Document date: 2021_1_1
ID: 6p97bk81
Snippet: The emergence of the influenza A(H1N1)pdm09 virus with the NA-H275Y mutation, which confers oseltamivir resistance, must be monitored, especially in patients undergoing neuraminidase inhibitor treatment. In this study, we developed a reverse transcription recombinase-aided amplification assay that has high sensitivity (detection limit: 1.0 × 101 copies/µL) and specificity for detecting the oseltamivir-resistant H275Y mutation; the assay is performed within 30 min at a constant temperature of 3

In this study, we developed a reverse transcription recombinase-aided amplification assay that has high sensitivity (detection limit: 1.0 × 101 copies/µL) and specificity for detecting the oseltamivir-resistant H275Y mutation; the assay is performed within 30 min at a constant temperature of 39° Celsius using an isothermal device. This method is suitable for the clinical application of targeted testing, thereby providing technical support for precision medicine in individual drug applications for patients with severe infection or immunosuppression.
