Abstract | Background: December 2021 witnessed an unprecedented increase in SARS-CoV-2 infections in addition to the circulation of influenza A and respiratory syncytial viruses (RSV). Due to increased testing demands for SARS-CoV-2, influenza, and RSV associated with the overall increase in symptomatic respiratory infections, there is an urgent need for multiplex, automated, and high throughput assays in the diagnostic laboratories. Methods: We compared the performance of the NeuMoDx™ Flu A-B/RSV/SARS-CoV-2 Vantage and the Alinity m Resp-4-Plex to the standard of care influenza A, B, RSV, and SARS-CoV-2 assays used at the Johns Hopkins Microbiology Laboratory. A total of 181 remnant nasopharyngeal swab (NPS) specimens positive for influenza A (n = 29), influenza B (n = 34), RSV (n = 40), SARS-CoV-2 (n = 33), influenza A/RSV (n = 1), and negatives (n = 44) were tested by either or both assays. Results: Both the NeuMoDx™ Flu A-B/RSV/SARS-CoV-2 Vantage and the Alinity m Resp-4-Plex assays showed 100% total agreement for all the tested analytes. For samples with available cycle threshold (Ct) values, comparable ranges were noted for all targets between the two assays and to the standard of care Ct values as well. Conclusion: The NeuMoDx™ Flu A-B/RSV/SARS-CoV-2 Vantage and the Alinity m Resp-4-Plex assays showed high sensitivity and accuracy for all the analytes included in both tests. Implementing these assays will assist the diagnostic laboratories with the surge of testing during the 2021-2022 influenza season. |
