The anti-A or anti-B isoantibodies or both (also called isohaemagglutinins) are produced by an individual against the antigens (A or B) on the RBCs of other blood groups. In a person with A blood group, the plasma will contain isoantibodies against B antigens, so immediately after transfusion of blood from B group the anti-B isohemagglutinins agglutinate the foreign red blood cells. Anti-A and anti-B antibodies (called Isohaemagglutinins), which are not present in the newborn, appear in the first years of life. It is possible that food and environmental antigens (bacterial, viral or plant antigens) have epitopes similar enough to A and B glycoprotein antigens.[2] The antibodies created against these environmental antigens in the first years of life can cross react with ABO-incompatible red blood cells when it comes in contact with during blood transfusion later in life. Anti-A and anti-B antibodies are usually IgM type. O-type individuals can produce IgG-type ABO antibodies
