For IgG antibody, the differences in Abs between control sera negative for SARS-CoV-2 antibody and sera positive for SARS-CoV-2 antibody were highly significant for all antigens, as shown by their p values ( p < 0.0001).
For IgG antibody, the differences in Abs between control sera negative for SARS-CoV-2 antibody and sera positive for SARS-CoV-2 antibody were highly significant for all antigens, as shown by their p values ( p < 0.0001).
C1q was also significant with p = 0.0495, while the rest of the antigens had non-significant reactions, with dsDNA at p = 0.1287, rheumatoid factor at p = 0.1804, ENA at p = 0.2342, and mitochondrial at p = 0.2611, and C1q almost significant with a p value of 0.05.
