We comparatively assessed sensitivities and specificities of 4 commercial enzyme-linked immunosorbent assays (ELISAs) and 2 rapid tests in 77 patients with polymerase chain reaction-confirmed severe acute respiratory syndrome coronavirus 2 infection, grouped by interval since symptom onset. In the current study, we compared the diagnostic ability of 4 enzyme-linked immunosorbent assays (ELISAs), which assess SARS-CoV-2-specific antibodies of different immunoglobulin (Ig) classes (Euroimmun SARS-CoV-2 IgA and IgG and Wantai SARS-CoV-2 IgM and total antibody), and 2 rapid tests (Wantai SARS-CoV-2 Ab Rapid Test and Hangzhou AllTest Biotech 2019-nCoV IgG/IgM Rapid Test) in 77 patients with symptomatic SARS-CoV-2 infection. Of the 77 patients with PCR-confirmed SARS-CoV-2 infection, 30 individuals (12 female, 18 male; median age, 58 years; age range, 15-83 years) provided serum/plasma samples that were obtained at symptom onset or 1-5 days after the onset of disease (group 1). ./cache/cord-334988-brumg6jh.txt ./txt/cord-334988-brumg6jh.txt
