MEDICAL PHYSIOLOGY

Detailed explanation-1: -Hemagglutination is the process by which red blood cells agglutinate, meaning clump or clog. The agglutin involved in hemagglutination is called hemagglutinin. In cross-matching, donor red blood cells and the recipient’s serum or plasma are incubated together.

Detailed explanation-2: -Blood clotting, or coagulation, is an important process that prevents excessive bleeding when a blood vessel is injured. Platelets (a type of blood cell) and proteins in your plasma (the liquid part of blood) work together to stop the bleeding by forming a clot over the injury.

Detailed explanation-3: -The blood will agglutinate if the antigens in the patient’s blood match the antibodies in the test tube. A antibodies attach to A antigens-they match like a lock and key-and thus form a clump of red blood cells.

Detailed explanation-4: -Blood typing the sample If your blood cells agglutinate, or clump together, it means your sample has reacted with one of the antibodies. This is called forward typing.
