What is the Kell blood classification system used for? This system refers to the presence or absence of K antigen, which has been found in pregnant women, in humans after transfusion. The presence of antigen K during blood transfusion is studied. This antigen was almost absent in the Chinese and was found in almost 2% of Koreans and 9% of the British. #bloodtype #bloodgroup #antigen #transfusion #Kellbloodtypes #Kellclassification #bloodgroupcompatibility #kellantigens #kellbloodgroup #kellbloodtransfusion
