Detailed explanation-1: -Mixing incompatible blood groups leads to blood clumping or agglutination, which is dangerous for individuals. Nobel Laureate Karl Landsteiner was involved in the discovery of both the AB0 blood group (in 1901) and Rh blood group (in 1937).
Detailed explanation-2: -Hemolytic transfusion reactions can cause the most serious problems, but these are rare. These reactions can occur when your ABO or Rh blood type and that of the transfused blood do not match. If this happens, your immune system attacks the transfused red blood cells. This can be life-threatening.
Detailed explanation-3: -When people who have one blood type receive blood from someone with a different blood type, it may cause their immune system to react. This is called ABO incompatibility. Due to modern testing techniques, this problem is very rare.
Detailed explanation-4: -Agglutination occurs when an insoluble or particle antigen interacts with an antibody. A positive reaction can be detected macroscopically in a short time. However, the antigen-antibody complex may be seen with the naked eye if the complex size is large. Both IgG or IgM could be involved in the agglutination reaction.
Detailed explanation-5: -Agglutination occurred when the RBC antigens were bound by the antibodies in the serum. He called the antigens A and B, and depending upon which antigen the RBC expressed, blood either belonged to blood group A or blood group B.
