Question: 1 / 400

A person with type AB blood has ________ and ________ antigens on the blood cells and _______ antibodies in the plasma.

A and B antigens, no antibodies

A person with type AB blood has both A and B antigens present on the surface of their red blood cells. This characteristic is crucial because it defines the blood type as AB. Additionally, individuals with type AB blood do not produce anti-A or anti-B antibodies in their plasma. The absence of these antibodies is significant because it allows the individual to receive blood from any ABO type without the risk of an immune reaction, as there are no antibodies to attack the foreign A or B antigens from other blood types. This unique combination of having both A and B antigens while lacking corresponding antibodies is what determines the compatibility of AB type blood in transfusion scenarios.
