Here, we retrospectively analyzed the comparative results of 182 paired dry nasopharyngeal swabs tested by Abbott ID NOW and nasopharyngeal swabs in viral transport medium by real-time RT-PCR methods. While the overall agreement was 96.2%, we found that of 15 samples that were tested positive with RT-PCR methods, 7 were missed by ID NOW, resulting in a false-negative rate of 47%.
