If you have type A blood, you cannot receive B blood because your body's anti-B antibodies will fight the B blood's B antigens. Type O is routinely in short supply and in high demand by hospitals both because it is the most common blood type and because type O negative blood is the universal blood type needed for emergency transfusions and for immune deficient infants. Why O negative blood can be used in transfusions for any blood type. For instance, a person with A blood type will have anti-B antibodies, and a person with B blood type will have anti-A antibodies. Universal donors are those with an O negative blood type. It meant his or her blood could be given to anyone, regardless of blood type, without causing a transfusion reaction. The AB blood type has both A and B antigens, and the O blood type has neither A nor B antigen.īy the time you are six months old, you naturally develop antibodies against the antigens your red blood cells lack. In the past, a person with blood type O negative blood was considered to be a universal donor. The A blood type has only the A antigen and the B blood type has only the B antigen.

Your ABO blood type is based on the presence or absence of the A and B antigens on your red blood cells. The antigens depend on the genes you inherit. AB positive is considered the universal recipient, and O negative is considered the universal donor. The red blood cells or RBCs present in the blood carry certain molecules, called antigens, on their surface that determine what blood group you have. There are four main blood types: A, AB, B and O.
