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: -Agglutination occurs when antibodies on one RBC bind to antigen on other RBCs, forming globular to amorphous, grapelike aggregates of RBCs. When present, RBC agglutination is supportive of immune-mediated hemolytic anemia (IMHA).
Detailed explanation-3: -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.
Detailed explanation-4: -Biological agglutination is the clumping of cells as aided by agglutinins. Agglutinins are substances in the blood that induce agglutination. Examples of agglutinins are antibodies and lectins.
