Therefore, if the antibody in the blood of the donor is separated before the blood is received, the person with blood type AB is a fully suitable recipient. However, they can only donate blood to people of the same blood type, for example, people of type AB can only donate blood to people of type AB. https://cdn.cybassets.com/s/files/5993/ckeditor/pictures/content_c041afb3-ce98-49a9-bf66-a7cd96a1ab7c.jpg ▼O type "Blood Type Tips" People with blood type O have neither A nor B antigens on the surface of their red blood cells.

However, in some places, such as Norway, Finland, Turkey, and Japan, there are more people with blood type A. Type A antigens are generally more common than type B antigens. The AB blood type has the A and B antigens at the same time, so it is also the least of the ABO blood types. The distribution of ABO blood types is related to region and race. The reason why humans develop antibodies to untouched antigens is unknown. It is generally believed that it may be related to the similarity between the antigens of certain bacteria and the glycoproteins of type A and B.
