9:56 1 LTE A blood type (also called a blood group) is defined as the classification of blood based on the presence or absence of inherited antigenic substances (which are substances that can trigger an immune response if they are foreign to the human body) on he surface of red blood cells (RBCs), A series of related blood types consaitutes a blood group system, such as the Rh or ABO system. There ane eight erent common blood types. The frequencies of the ABO and Rth blood types vary om population to There are 4 major blood groups determined by the presence or absence of two antigens (A and B) on the surface of red blood cells Blood Group Antigen Has only A antigen on red cells (and B antibody in the plasma) Has only B antigen on red cells (and A antibody in the plasma) Has both A and B antigens on red cells (but neither A nor B antibody in the plasma) Has neither A nor B antigens on red cells (but both A and B antibody are in the plasma) AB 0 In addition to the A and B antigens, there is a third antigen called the Rth factor, which can be either present () or absent (- Since some antigens can trgger a patients immune system to attack the transfused blood, safe blood ransfusions depend on careful blood typing and cross-matching In general, Rth negative blood is given o Rh-negative patients, and Rh positive blood or Rh negaltive blood may be given to R positive patients The universal red cell donor has Type O negative blood type. The universal plasma donor has Type AB postive blood type. Determining a persons blood ABO type is easy and inexpensive and can be obtained from a few drops of blood A senum containing anti-A antibodies is mixed with some of the blood. Anolther serum with anti-B ansbodies is mixed with the remaining sample. Whether or not aggluination occurs in either sample indicates the ABO type is a ple process of einination of the possibilities. For instance, if an individuals blood sample is agglutinated by the ant-A antibody, but not the anti-B antibody, t means that the A antigen is present but not the B antigen. Therefore, the blood type is A
