Detailed explanation-1: -If the blood does not react to any of the anti-A or anti-B antibodies, it’s blood group O. A series of tests with different types of antibody can be used to identify your blood group.
Detailed explanation-2: -A person with the Rh positive factor will not make anti-Rh antibodies. Those with Rh negative factor will produce the antibodies. Therefore, someone with Rh+ blood can receive both Rh+ and Rh-transfusions, but those with Rh-can only receive Rh-blood.
Detailed explanation-3: -Thus if blood with blood group B comes in contact with the blood group A, then agglutination takes place due to cross-reaction and the blood is destroyed. Thus if a person has blood type B, his plasma will have anti-A antibodies, not Anti-B.
Detailed explanation-4: -When anti-A antibodies (added to the first well) contact A antigens on AB erythrocytes, they will cause agglutination. Similarly, when anti-B antibodies contact B antigens on AB erythrocytes, they will cause agglutination.
Detailed explanation-5: -The immune system forms antibodies against whichever ABO blood group antigens are not found on the individual’s RBCs. Thus, a group A individual will have anti-B antibodies and a group B individual will have anti-A antibodies.
