Recently, the novel multiplex real-time reverse transcription-polymerase chain reaction assay AMPLIQUICK<jats:sup>\u00ae<\/jats:sup> Respiratory Triplex (BioSynex SA, Illkirch-Graffenstaden, France) allows simultaneous detection and differentiation of SARS-CoV-2, influenza A, influenza B, and RSV in respiratory tract samples. We herein evaluated the performance of the AMPLIQUICK<jats:sup>\u00ae<\/jats:sup> Respiratory Triplex for the detection of the four viruses in respiratory specimens, using Allplex\u2122 Respiratory Panel 1 and 2019-nCoV assays (Seegene, Seoul, Korea) as reference comparator assays. A total of 359 archived predetermined respiratory samples, including 83, 145, 19 and 95 positive specimens for SARS-CoV-2, influenza A, influenza B and RSV respectively, were included. The AMPLIQUICK<jats:sup>\u00ae<\/jats:sup> Respiratory Triplex showed high concordance with the reference assays, with an overall agreement for SARS-CoV-2, influenza A, influenza B, and RSV at 97.6%, 98.8%, 98.3% and 100.0%, respectively, and high \u03ba values ranging from 0.93 to 1.00, indicating an almost perfect agreement between assays. Furthermore, high correlations of cycle threshold (C<jats:sub>t<\/jats:sub>) values were observed for positive samples of the four viruses between the AMPLIQUICK<jats:sup>\u00ae<\/jats:sup> Respiratory Triplex and comparator assays, with an overall high agreement between C<jats:sub>t<\/jats:sub> values assessed by Bland-Altman analyses. In conclusion, these observations demonstrate that the multiplex AMPLIQUICK<jats:sup>\u00ae<\/jats:sup> Respiratory Triplex is a reliable assay for the qualitative detection and differentiation of SARS-CoV-2, influenza A, influenza B, and RSV in respiratory specimens, which may prove useful for streamlining diagnostics during the winter influenza-seasons.<\/jats:p>","DOI":"10.1371\/journal.pone.0262258","type":"journal-article","created":{"date-parts":[[2022,1,5]],"date-time":"2022-01-05T18:29:53Z","timestamp":1641407393000},"page":"e0262258","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":12,"title":["Analytical
