Question

Give reason for the following :
The blood groups of both the donor and recipient must be known before transfusing blood.

Answer 1

Sometimes it becomes necessary to inject blood into the body of patients undergoing surgical operation. This is called blood-transfusion. Blood taken from a healthy person(donor) is introduced through one of the patient’s veins. But for doing so, it is necessary that the kind or the type of blood to be transfused should match with the type of blood of the receiving person (recipient).RBC’s of human being have specific glycoproteins on their surface. These proteins are called antigens. The plasma of the blood has its complementary antibodies. Knowing the blood group of the donor and the recipient is required helps matching of the blood antigens so that the blood cells of the donor are not destroyed by the recipients antibodies
