Blood Group Test Blood typing procedure: 1. Mix! First mix the patient's blood with three different reagents including either of the three different antibodies, A, B or Rh antibodies! 2. Look for agglutination! Then you take a look at what has happened. In which mixtures has clumping, or agglutination, occurred? The agglutination indicates that the blood has reacted with a certain antibody and is therefore not compatible with blood containing that kind of antibody. If the blood does not agglutinate, it indicates that the blood does not have the antigens binding the special antibody in the reagent. 3. Figure out the ABO blood group! Start by taking a look at the test tubes containing A and B antibodies. Has the blood agglutinated in either of these two tubes? No agglutination in test tube A, indicates that the patient's red blood cells do not have A antigens. Agglutination in the tube containing B antibodies indicates that the patients' red blood
