Swedish researchers later found evidence leading to abolishment of the Apae subgroup and establishment instead of the FORS blood group system (System 31 - ISBT, 2012). It is important to know the prevalence of antibodies in order to make the best decisions in transfusion medicine. Cells expressing the Forssman saccharide, such as sheep erythrocytes, are needed to detect the anti-Forssman antibody. The aim of this study was to define the prevalence of human anti-Forssman antibody.engAntigénios de Grupos SanguíneosTipagem e Reações Cruzadas SanguíneasAntigénio de ForssmanIsoanticorposAnimaisOligossacarídeosjournal article10.2450/2016.0120-16
