cord-349744-8cg5yj20	Lassaunière, Ria	Evaluation of nine commercial SARS-CoV-2 immunoassays	2020-04-10		.txt	text/plain	2649	145	53	The results showed 100% specificity for the Wantai SARS-CoV-2 Total Antibody ELISA, 93% for the Euroimmun IgA ELISA, and 96% for the Euroimmun IgG ELISA with sensitivities of 90%, 90%, and 65%, respectively. While the four POC tests evaluated according to illness duration were often weakly positive or detected only IgG or IgM during the early phase (data not shown), their sensitivities were comparable to the Wantai Total Ab ELISA and Euroimmun IgA ELISA in all three phases. In the present study, three SARS-CoV-2-specific commercial ELISA assays and six POC rapid tests were evaluated using sera from hospitalized adult patients with PCR-confirmed diagnoses for SARS-CoV-2 and a collection of control serum samples taken before the emergence of the virus in China in December 2019. Overall, the Wantai Total Ab ELISA had superior sensitivity and specificity compared to both Euroimmun IgA and IgG ELISAs. The POC tests varied notably, with the best performance observed for the test produced by AutoBio Diagnostics, followed by the tests produced by Dynamiker Biotechnology and CTK Biotech.	./cache/cord-349744-8cg5yj20.txt	./txt/cord-349744-8cg5yj20.txt
