What agglutinogens are present in type AB blood?

Type AB blood is characterized by the presence of both A and B agglutinogens on the surface of red blood cells. Agglutinogens are specific antigenic substances that can elicit an immune response. In the case of blood types, agglutinogens determine compatibility for blood transfusions and the individual's blood characteristics.

Individuals with type AB blood express both A and B antigens, which means they do not produce antibodies against either A or B blood types. This unique situation allows people with type AB blood to receive blood from any ABO type without the risk of agglutination, making them universal recipients in terms of transfusions.

This distinction is important not just for transfusion medicine but also for understanding the underlying genetics and immunology of blood types. Therefore, the presence of both A and B agglutinogens in type AB blood is what defines this blood type and elucidates its behavior in the context of blood compatibility and transfusion practices.
