About The Test
How is it used
1. Who are universal blood donors and recipients?
Blood group O negative is considered as universal blood donors as they do not have any antigens, that is antigen A, B or Rh. The blood group AB positive is considered as universal blood recipient as they do not have any antibodies in their blood to react with the antigens.
2. What are the other types of blood groups?
Other than ABO and Rh blood grouping, there are many other minor groups like Kell, Kidd, Duffy etc. As incompatibility is more common with ABO and Rh blood groups it is significant unlike the other groups.
3. Why is it important to know Blood group?
It is important to know a person’s blood group, to prevent antigen antibody reactions and the complications associated with it. If a person’s blood group B (which contains B antigens and A antibodies) and he receives blood group A (which contains A antigens and B antibodies), the recipient’s A antibodies reacts with A antigens of donor, destroy them and hence results in complications.
