Comparison of Cepheid Xpert Xpress and Abbott ID Now to Roche cobas for the Rapid Detection of SARS-CoV-2	2020-05-13		.txt	text/plain	2230	141	57	OBJECTIVE: This study aimed to compare two recently-authorized rapid tests, Cepheid Xpert Xpress SARS-CoV-2 and Abbott ID Now SARS-CoV-2, to the Roche cobas SARS-CoV-2 assay for samples with low, medium, and high viral concentrations. STUDY DESIGN: A total of 113 nasopharyngeal swabs from remnant patient samples were tested, including 88 positives spanning the full range of observed Ct values on the cobas assay. CONCLUSIONS: While Xpert showed high agreement with cobas across a wide range of viral concentrations, this study highlights an important limitation of ID Now for specimens collected in viral or universal transport media with low viral concentrations. Utilizing the high volume of patient testing performed at our medical center in New York City, we sought to evaluate and compare the performance of these two rapid assays across a wide range of clinical samples. Deidentified remnant patient samples that underwent routine clinical testing with the cobas SARS-CoV-2 assay on the 6800 platform (Roche Diagnostics, Indianapolis, IN) were used to evaluate the Xpert and ID Now assays.	./cache/cord-289740-nsiycudn.txt	./txt/cord-289740-nsiycudn.txt
