Detailed explanation-1: -For example, people with type A blood will have the A antigen on the surface of their red cells (as shown in the table below). As a result, anti-A antibodies will not be produced by them because they would cause the destruction of their own blood.
Detailed explanation-2: -If your blood is A positive (A+), it means that your blood contains type-A antigens with the presence of a protein called the rhesus (Rh) factor.
Detailed explanation-3: -Blood group antigens are found on the surface of red blood cells and are ignored by the immune system. But antigens of another blood type will be seen as foreign, and attacked by antibodies. Blood group A has A antigens on the red blood cells with anti-B antibodies in the plasma.
Detailed explanation-4: -The erythrocyte antigens are situated on the membrane of the red blood cells. From: Encyclopedia of Analytical Science (Second Edition), 2005.
