Title: Evaluation of nine commercial SARS-CoV-2 immunoassays Document date: 2020_4_10
ID: 8cg5yj20_15
Snippet: The specificity of the six POC tests were evaluated primarily on control samples that showed some crossreactivity in the SARS-CoV-2 ELISA assays; the number of control sera tested varied between the different POC tests ( Table 1 ). The POC tests manufactured by Dynamiker Biotechnology, CTK Biotech, AutoBio Diagnostics and Artron Laboratories had a 100% specificity, whereas the test from Acro Biotech and Hangzhou AllTest Biotech had a specificity .....
Document: The specificity of the six POC tests were evaluated primarily on control samples that showed some crossreactivity in the SARS-CoV-2 ELISA assays; the number of control sera tested varied between the different POC tests ( Table 1 ). The POC tests manufactured by Dynamiker Biotechnology, CTK Biotech, AutoBio Diagnostics and Artron Laboratories had a 100% specificity, whereas the test from Acro Biotech and Hangzhou AllTest Biotech had a specificity of 80% and 87%, respectively. For the latter two tests, crossreactivity was only observed for IgM. The Acro Biotech test cross-reacted with a control serum sample from a human coronavirus HKU1 patient.
