Question

Why is it important to determine the blood types of the donor and the recipient in transfusions?

Answer 1

Red blood cells have exclusive antigens inside the outer floor of their plasma membrane; for example, the antigens A and B of the ABO device are glycoproteins of the membrane.If a donor has purple blood cells with antigens not gift in the red blood cells of the recipient (a lack of transfusion compatibility), the immune system of the recipient acknowledges those molecules as real antigens (or rather, overseas substances) and triggers a protection reaction, generating unique antibodies in opposition to the ones antigens. The transfused red blood cells are then destroyed by way of these antibodies and the recipient can also even die.
