Blood Typing
...a universal recipient because there are no antibodies, so they can accept any type of blood without serious clotting occurring. Materials: - Blood Lance - Alcohol swab - Microscope slide - Two toothpicks - Anti-a serum - Paper with A and B labeled on it - Anti-b serum Procedure: - Wash your hands with soap and water - Get all of your materials - Place your microscope slide no your labeled paper - Shake your hand until blood goes to your finger - Wipe your finger with the alcohol swab - Take your blood lance and prick your self with it - Place to large drops of blood on your microscope, one drop over the part labeled A and another on the part labeled B - Put some anti-a serum on the drop labeled A, and some anti-b serum on the drop labeled B - Record your observations Observations: Blood Type Class Frequency % USA Frequency A 6 31 40 B 6 31 10 AB 0 0 4 OO 7 36 46 Analysis: 1. Agglutination is when and antibody attacks an unknown blood typing, bunching the blood cells together, not letting them spread. In blood clotting a chemical chain reaction occurs to stop a cut from bleeding, not causing problems to the blood flow. 2. A) To determine if you have blood type B you would add some antibodies coded to attack the protein antigen B. If you have blood type B then agglutination will occur. B) To determine if you have blood type OO then you would need to add both antibodies for A and B too your blood samples, if no agglutination will occur, because there are no protein antigen markers on that blood type. 3. I have OO type blood. I could give blood to all of the blood types. I can only receive blood from another OO blood type. I can give blood to anyone because there are no protein antigen markers on my blood so the antibodies will not attack it. 4. The most common blood type in my class is OO, and the least common is AB. 5. OO is a universal don...
