Impact of SARS-CoV-2 variants on antibody tests
Since end of 2020, different SARS-CoV-2 variants have appeared worldwide − alpha (B.1.1.7), beta (B.1.351), gamma (P.1/B.1.1.128) and delta (B1.617.2) − which are in part more contagious than the original virus type and are therefore spreading more quickly within populations. These variants reveal genetic changes (mutations) in the so-called receptor binding domain (RBD), which is […]
