[h=3]Abstract[/h] [h=4]BACKGROUND:[/h] Rapid diagnosis of influenza A and B is important for direct treatment decisions in patient care and for the reduction of in-hospital transmissions. The new real-time PCR based molecular point-of-care (POC) assay, the cobas[SUP]?[/SUP] Influenza A/B test on the cobas[SUP]?[/SUP] Liat? System (cobas[SUP]?[/SUP] Liat? Influenza A/B assay), generated a PCR result in less than 20 minutes, was evaluated for the detection of influenza A and B.
[h=4]METHOD OF THE STUDY:[/h] 121 retrospectively collected respiratory specimens, previously analyzed with a routine influenza A/B test (Diagenode) were tested using the cobas[SUP]?[/SUP] Liat? Influenza A/B assay.
[h=4]RESULTS:[/h] The cobas[SUP]?[/SUP] Liat? Influenza A/B assay allows influenza A and B testing by RT-PCR within 20 minutes. This assay detected influenza A in 51 of 56 samples positive by the Diagenode test. The 5 discrepant results were retested with the Cepheid Influenza A/B test, confirming 2 positive cases. All 30 influenza B Diagenode positive samples were found positive by the cobas[SUP]?[/SUP] Liat? Influenza A/B assay. Control samples (viral negative and non-influenza pathogens) were all negative by the cobas[SUP]?[/SUP] Liat? Influenza A/B assay. The cobas[SUP]?[/SUP] Liat[SUP]?[/SUP] Influenza A/B assay showed a sensitivity for influenza A/B of 96% and 100%, respectively, and 100% specificity for both targets.
[h=4]CONCLUSION:[/h] The cobas[SUP]?[/SUP] Liat? Influenza A/B assay is a useful tool for accurate, rapid, and sensitive detection of influenza A and B, offering timely and personalized patient management and infection control when implemented at the point-of-care.
