"🅰️🅱️" is a representation commonly used to refer to the blood type AB. Blood Type AB is one of the four main blood types, determined by the presence of both A and B antigens on the surface of red blood cells. Individuals with this blood type possess unique characteristics, as they inherit both A and B alleles from their parents. This makes them universal recipients for blood transfusions since they can receive blood from donors with A, B, AB, or O blood types.
