Analytical and clinical performances of five immunoassays for the detection of SARS-CoV-2 antibodies in comparison with neutralization activity 2020-08-04 .txt text/plain 2282 134 46 In 184 serum samples from 130 COVID-19 patients and 54 SARS-CoV-2 negative subjects, the analytical and clinical performances of four commercially available chemiluminescent assays (Abbott SARS-Cov-2 IgG, Roche Elecsys anti-SARS-CoV-2, Ortho SARS-CoV-2 total and IgG) and one enzyme-linked immunosorbent assay (Diesse ENZY-WELL SARS-CoV-2 IgG) were evaluated and compared with the neutralization activity achieved using the plaque reduction neutralization test (PRNT). On limiting the analysis to samples collected 12 days after onset of symptoms, the sensitivity of all assays increased, the highest value (95.2%) being obtained with VITRO Anti-SARS-CoV-2 Total and Architect SARS-CoV-2 IgG. 54 SARS-CoV-2 negative subjects (33 healthcare workers, 21 autoimmune patients, 8 pregnant women) were included in the study ( Moreover, Liaison SARS-CoV-2 S1/S2 IgG (Diasorin, Sallugia-VC, Italy), ENZY-Well SARS-CoV-2 IgA and IgM were evaluated for the correlation with the neutralization results. . To provide insight on neutralization activity compared with immunoassays results, PRNT assay was performed on 52 samples from SARS-CoV-2 positive subjects. ./cache/cord-346960-3empldlo.txt ./txt/cord-346960-3empldlo.txt
