Abstract
We evaluated the analytical performance of ID NOW™ COVID-19 2.0 assay versus conventional real-time reverse transcription-polymerase chain reaction (RT-PCR) using a total of 792 clinical samples from nasopharyngeal and oropharyngeal swabs, stored in frozen universal transport medium samples. Positive percent agreement (PPA) and negative percent agreement of ID NOW were 97.6 % and 100 %, respectively. The overall percent agreement between ID NOW and RT-PCR was 99.5 %. The PPA of ID NOW in detecting SARS-CoV-2 in 164 RT-PCR positive patients, all of whom had symptoms related COVID-19, was 97.1 % within 8 days since symptom onset, 97.9 % from 8 to 14 days since symptom onset, and 97.6 % after 14 days since symptom onset, with no significant difference between the days since symptom onset. The ID NOW assay demonstrated good performance, providing a rapid and randomly accessible alternative to conventional RT-PCR for timely SARS-CoV-2 detection, particularly in situations requiring rapid results for patient care.
