ID NOW: A NAAT System Solution for the Rapid and Accurate Detection of SARS-CoV-2 with VTM Sampling

Abstract

ID NOW™ COVID-19 is a rapid molecular test for the detection of SARS-CoV-2. According to its instructions for use, this point-of-care test should be performed on dry nasopharyngeal swab (NPS) specimens. However, this method completely consumes the swab, with the limitation that additional analyses cannot be performed if required. The aim of this work was to evaluate the analytical performance of the ID NOW™ COVID-19 using NPS sampled on a viral transport medium. When compared to a reference RT-PCR, the positive and negative percent agreement was 86% and 100%, respectively. False negatives were associated with high RT-PCR Ct values.
