MODEL RELEASED. Blood group identification. Haematologist determining the blood group,or type,of donor blood samples. There are four human blood types: A,B,AB and O. Type A blood has type A antigens (surface proteins) on its red blood cells and anti-B antibodies (proteins that bind to type B antigens) in its serum. Type B blood is the reverse. AB blood has no antibodies,but has both A and B antigens on its cells. Type O blood has both antibodies but no antigens. The blood type is identified by adding an antibody serum containing either only anti-A,only anti-B or both anti-A and anti-B. Identifying the blood type prevents patients from having fatal immune responses when receiving donated blood | |
