The aim of our study was to investigate the difference in the anti-SARS-CoV-2 antibodies assessment with two various assays. 127 patients exposed to SARS-CoV-2 were included. Two serological tests were used: SARS-CoV-2 IgG CMIA on the Alinity system (ABBOTT) and LIAISON® SARS-CoV-2 S1/S2 IgG CLIA (DiaSorin). Both assays exhibited 96.85% (123/127 patients) overall compatibility. In 2 cases the positive results in N-based test, were negative in S-based test, and in 2 cases negative results in S-based test were positive in N-based test. Based on the results of our study we concluded that the assessment of anti-SARS-CoV-2 antibodies against N and S protein in population medicine shows comparable usefulness of both tests.
