Comparative study of a new commercial recombinant line assay and two immunoassays for detection of SARS-CoV-2 IgG antibodies in PCR-confirmed outpatients

Abstract

Commercially available immunoassays have been developed for detection of antibodies against SARS-CoV-2. However, equivocal and discrepant results between different immunoassay can occur requiring further assessment by confirmatory tests.
