Detailed explanation-1: -The liquid part of your blood without cells (serum) is mixed with blood that is known to be type A and type B. People with type A blood have anti-B antibodies. People with type B blood have anti-A antibodies. Type O blood contains both types of antibodies.
Detailed explanation-2: -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.
Detailed explanation-3: -The Anti-A, Anti-B, and Anti-A, B reagents are used in the red blood cell determination of the ABO blood group. They are used to determine the absence or presence of erythrocytic antigens A and/or B on the surface of human red blood cells.
Detailed explanation-4: -ABO antigens and antibodies These naturally occurring antibodies are mainly IgM immunoglobulins. They attack and rapidly destroy red cells carrying the corresponding antigen. For example, anti-A attacks red cells of Group A or AB. Anti-B attacks red cells of Group B or AB.
