Which coronavirus antibody test is the best?

If you want to check whether you have been infected with the SARS-CoV-2 coronavirus, you can choose any antibody test available in the pharmacy. However, when we want to find out whether our body has produced antibodies after taking the vaccine, you should choose a test based on the S antigen, e.g. Biosynex Autotest COVID-19 (not on the N antigen) - information about the technology used is included in the test leaflet. The Biosynex test can be purchased at a stationary pharmacy or online with home shipping: https://www.gdziepolek.pl/produkty/113688/test-na-koronawirusa-covid-19-na-przeciwciala-biosynex-autotest-covid-19-test/apteki?pvid=268845#internetowe Another test available at the pharmacy (does not detect antibodies after vaccination) is, for example, https://www.gdziepolek.pl/produkty/107635/domowy-test-na-koronawirusa-na-przeciwciala-igm-igg-przeciwko-covid-19-primacovi/apteki?pvid=260158#internetowe About what test We also write in our analysis of antibody tests: https://www.gdziepolek.pl/artykuly/jaki-test-na-przeciwciala-koronawirusa-wybrac
