A person with type A blood receiving a transfusion of type B or AB blood would have an ABO incompatibility reaction. In an ABO incompatibility reaction, your immune system attacks the new blood cells and destroys them. ... However, you can only donate blood to other people who have type AB blood. Hope this helps you! Have a good day!

When two different types of bloods are mixed together, it causes blood clumping or agglutination of blood. When two different blood groups are combined the antigen present in one group binds with the antibodies of other blood group and results in agglutination of blood. Hence these clumped blood blocks the blood vessels and thus prevents blood circulation. Also the immune response caused by the antibodies may have an adverse effect which results in the rupture of erythrocytes which may be fatal for the patient.
