BLOOD GROUP B

People who are blood group B have type B antigens present on the surface of red blood cells and anti-A antibodies present in their blood:

Because of this, people with blood group B can only receive group B or O blood. They cannot receive group A or AB blood, as the anti-A antibodies in their blood will attach to the type A antigens and destroy the blood cells, causing an immune response that can ultimately be fatal.

  • If someone with blood group B receives group A blood, the anti-A antibodies in their blood will attach to the type A antigens and destroy the blood cells.

  • If someone with blood group B receives group AB blood, the anti-A antibodies in their blood will attach to the type A antigens and destroy the blood cells.

However, people with blood group B can receive group O blood as it does not contain A or B antigens.
