cord-266348-tbr2ynx0	Stroemer, A.	Diagnostic accuracy of six commercial SARS-CoV-2 IgG/total antibody assays and identification of SARS-CoV-2 neutralizing antibodies in convalescent sera	2020-06-17		.txt	text/plain	2893	215	61	Here, we compare the diagnostic accuracy of six commercially available SARS-CoV-2 IgG (Abbott SARS-CoV-2 IgG; Diasorin Liaison SARS-CoV-2 S1/2 IgG; Epitope EDI Novel Coronavirus COVID-19 IgG ELISA Kit; Euroimmun Anti-SARS-CoV-2 ELISA (IgG); Mikrogen recomWell SARS-CoV-2 IgG) or total SARS-CoV-2 antibody assays (Roche Elecsys Anti-SARS-CoV-2). The majority of assay results were confirmed in a laboratory-developed plaque reduction neutralization test and by a SARS-CoV-2 IgG-specific line assay including measurement of generally low IgG avidities (Mikrogen recomLine Coronavirus IgG [Aviditaet], prototype). Out 132 of the remaining 34 samples, only one serum (#20; Figure 1 ) which was obtained ten days after a positive 133 RT-PCR was tested negative for SARS-CoV-2 IgG/total antibodies in the six assays. Six of them -including three family members of a 153 confirmed COVID-19 case (#22; Figure 1 ) -were classified SARS-CoV-2 IgG/total antibody positive by the 154 majority of the tests.	./cache/cord-266348-tbr2ynx0.txt	./txt/cord-266348-tbr2ynx0.txt
