Aim: To evaluate the Alere™ i Influenza A&amp;B assay and the Xpert®Flu/RSV XC assay using nasopharyngeal aspirates and swabs not provided in the commercial kits. Methods: Specimens were tested with the Alere i Influenza A&amp;B and the Xpert Flu/RSV XC assays and compared with reference methods. Results: Compared with the comparator methods and following discordant analysis, the sensitivity of the i Influenza A&amp;B assay was 63.3% for influenza A and 83.3% for influenza B. For the Xpert Flu/RSV XC assay, sensitivity was 100% for influenza A and B and respiratory syncytial virus. The specificity for all test systems was 100%. Conclusion: The Xpert Flu/RSV XC assay out-performed the Alere i Influenza A&amp;B assay in all diagnostic characteristics evaluated.</jats:p
