MICROANATOMY

Detailed explanation-1: -If you receive blood that is not compatible with your blood, your body produces antibodies to destroy the donor’s blood cells. This process causes the transfusion reaction. Blood that you receive in a transfusion must be compatible with your own blood.

Detailed explanation-2: -For example, anti-A attacks red cells of Group A or AB. Anti-B attacks red cells of Group B or AB. If ABO incompatible red cells are transfused, red cell haemolysis can occur. For example if group A red cells are infused into a recipient who is group O, the recipient’s anti-A antibodies bind to the transfused cells.

Detailed explanation-3: -No agglutination indicates that the patient’s red blood cells don’t have Rh antigens, thus the blood is Rh-.

Detailed explanation-4: -Agglutination occurs when antibodies on one RBC bind to antigen on other RBCs, forming globular to amorphous, grapelike aggregates of RBCs.
