An "in-house" RT-PCR was used as the reference method. Sensitivity of AL-Flu, SDB, and SPX was 71.7%, 34.8%, and 100%, respectively. Specificity was 100% for all techniques. The turnaround time was 13min for AL-Flu, 15min for SDB, and 75min for SPX. The Alere™ i Influenza A&B assay is an optimal point-of-care assay for influenza diagnosis in clinical emergency settings, and is more sensitive and specific than antigen detection methods.enDetección rápidaGripeInfluenzaMolecular testingMétodo molecularRapid detectionHumansInfluenza A virusInfluenza B virusInfluenza, HumanMolecular Diagnostic TechniquesNucleic Acid Amplification TechniquesRetrospective StudiesTime Factorsresearch article26620605open access10.1016/j.eimc.2015.10.0061578-1852PMC7103361https://doi.org/10.1016/j.eimc.2015.10.006https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7103361/pdf
