Study Notes
ABO Blood Grouping
- The ABO blood grouping system is based on the presence or absence of antigens A and B on red blood cells.
- The presence of antigens A and B is determined by agglutination reactions with known antibodies.
- Agglutination occurs when an antigen reacts with its corresponding antibody.
- Blood type is determined by the presence or absence of agglutination with anti-A and anti-B sera.
- The table below summarizes the reactions observed in the ABO blood grouping system:
ABO Blood Grouping System
- Blood Group A: Contains antigen A and anti-B antibody.
- Blood Group B: Contains antigen B and anti-A antibody.
- Blood Group AB: Contains both antigens A and B but no antibodies.
- Blood Group O: Contains no antigens but has both anti-A and anti-B antibodies.
Example Reactions
- Sample 1: Agglutinates with anti-A and anti-B sera, indicating blood group AB.
- Sample 2: Does not agglutinate with anti-A sera but agglutinates with anti-B sera, indicating blood group B.
- Sample 3: Agglutinates with anti-A and anti-B sera, indicating blood group AB.
- Sample 4: Doesn't agglutinate with either anti-A or anti-B sera, indicating blood group O.
