Performance of ID NOW Influenza A&B 2

Abstract

ID NOW™ INFLUENZA A&B 2 is a point-of-care assay for rapid molecular diagnosis of Influenza A and B. The present study aims to evaluate the performance of ID NOW™ INFLUENZA A&B 2 compared to a reference RT-PCR assay. A total of 67 nasopharyngeal swabs from 67 patients for screening of Influenza A and B by RT-PCR (Allplex™ RP1) were also tested with ID NOW assay. Of the seventeen positive Influenza A and five positive Influenza B, fifteen (88%) and five (100%), respectively, were also detected by the ID NOW assay. The overall agreement with the reference test was 95.5%. The sensitivity was 88.2% for Influenza type A and 100% for Influenza type B, and the specificity was equal to or higher than 96% for both.
