Relative to qPCR, the BioFire assay had superior performance compared to rapid test in the context of a controlled influenza challenge study. Methods: The objective of our study was to evaluate the sensitivity and specificity of rapid antigen detection tests versus those of reverse transcriptase PCR (RT-PCR) using oral, anterior nasal, and nasopharyngeal swabs. For antibody tests, it is the ability to identify samples where no SARS-CoV-2 antibodies are present. hb```f``tAX,- When also patients that were graded as high suspicion but never tested positive were included in the denominator, the sensitivity (95% CI) was: 67.5% (62.9-71.9%) inpatients; 34.9% (31.4-38.5%) outpatients; 47.3% (44.4-50.3%) all. endstream endobj 1773 0 obj <>/Metadata 142 0 R/Outlines 202 0 R/Pages 1768 0 R/StructTreeRoot 258 0 R/Type/Catalog>> endobj 1774 0 obj <>/ExtGState<>/Font<>/XObject<>>>/Rotate 0/StructParents 0/Tabs/S/Type/Page>> endobj 1775 0 obj <>stream Epub 2022 Nov 17. -, Moore NM, Li H, Schejbal D, Lindsley J, Hayden MK. 2021 Jan 8;22(1):39. doi: 10.1186/s13063-020-04982-z.
