If a patient with type AB blood receives a transfusion of type B blood, it would not result in an immediate adverse reaction. This is because patients with type AB blood have both A and B antigens on the surface of their red blood cells, as well as both A and B antibodies in their plasma. However, since the patient already has the B antigen, there would be no immune response triggered by the transfusion of type B blood.

In general, ABO blood typing system determines the compatibility of blood transfusion. Type A blood has A antigens on red blood cells and antibodies against B antigens in plasma, while type B blood has B antigens on red blood cells and antibodies against A antigens in plasma.

In cases of incompatible blood transfusions, when the recipient's plasma contains antibodies against the donor's antigens, it can result in an immune reaction. This reaction usually involves a process called agglutination, where the antibodies bind to the incompatible antigens, causing the red blood cells to clump together. This can lead to severe complications such as organ damage, clot formation, and even death.

However, in the case of a patient with type AB blood, they have both A and B antigens on their red blood cells, making them universal recipients. Since they do not have antibodies against either A or B antigens in their plasma, they can safely receive transfusions of both type A and type B blood, as well as type AB blood.

In summary, if a patient with type AB blood receives a transfusion of type B blood, no adverse immune reaction is expected because the patient already has the B antigen and does not have antibodies against B antigens in their plasma.
