AB– blood group: It possesses surface antigens on the RBC membrane that are A and B antigens and no antibodies in the blood plasma.B– blood group: It possesses B-surface antigens are present on the RBC membrane, and the antibodies in the blood plasma are anti-A type.A– blood group: It possesses A-surface antigens are present on the RBC membrane, and the antibodies in the blood plasma are anti-B type.Introduced the blood group inheritance pattern for multiple allelesĪBO blood group system was accepted by National Research CouncilĪwarded by Nobel prize in physiology and medicineĪBO blood group system was universally followedĭescribed the presence of polylactosamine chains in the human erythrocyte glycoproteinsĪccording to the ABO blood group system, there are four blood groups, namely A, B, AB and O. Ludwik Hirszfeld and Emil Freihers Von Dungernĭescribed genetic inheritance of blood groupīlood clot prevention technique was introduced during first world war by citric acid History of ABO Blood Grouping Year of discoveryĬlassify human blood into A, B & C group based on agglutination reactionĬlassify blood type O, A, B & AB in roman letters I, II, III & IV Antibodies are the molecules that work against the antigen and also called agglutinins that float in the blood plasma. Then the WBCs starts making antibodies against that particular antigen. If the antigen is foreign, it will induce the immune response, after which the WBCs come into action to recognize these antigens. The antigens are mainly glycolipids which are of two types, namely self-antigens and foreign-antigens. This surface protein called antigen or agglutinogen. In the ABO blood grouping system, agglutination reaction takes place between the surface proteins that are found on the red blood cell surface. ABO blood group is also present in some other animals like gorillas, chimpanzees etc. These antibodies belong to the IgM class. Individuals above 3-6 month have naturally occurring antibodies which arise without any antigenic stimulation from the maternal placenta. The antigens if absent on the RBCs membrane, then the corresponding antibodies must be present in the blood plasma. If agglutination occurs in the RBCs, then the corresponding antibody must be absent in the blood plasma. The ABO blood group system has type A, B, AB and O phenotypes and it is used to identify the type of surface antigens and antibodies present in the donor’s blood. Besides, we will also discuss some of the discoveries, facts and the overview of the ABO blood group system. In this context, we will study the principle, method and result interpretation of the ABO blood typing. The playful teaching method in this well thought out production creates a desire to learn how one determines blood types, their differences and which ones are compatible for blood transfusions.The antigens of the ABO blood group system are glycolipid in nature, and the antibodies are predominantly of IgM type. " The winner has created a minimalistic but, at the same time, captivating graphic design which grabs the user's curiosity. The Blood Typing Game - 2012 winner of the 'Best game category' by Swedish Learning Awards People with blood type AB Rh+ can recieve blood from all blood types and therefore are called Universal receivers. People with O Rh+ can receive both O Rh+ and O Rh- blood. People with O Rh- blood can only receive O Rh- blood. This "Compatible blood chart" refers to blood transfusions with red blood cells. Look at the "Compatible blood chart" below!ĪB can receive blood from: AB, A, B and O People can happily receive blood from the same blood type as their own, but they have antibodies against any antigens not found on their own red blood cells.
