If a person receives blood with different antigens than those in their body, there is a high chance that their body will reject and attack the new blood cells. It is therefore vital to receive a matching blood type during transfusion. Almost anyone with any blood type can receive these red blood cells. Antibodies are produced by white blood cells and target any antigen that is seen as a foreign object. O negative blood contains no A, B, or RhD antigens. Transporting molecules in and out of the cellĪntigens and antibodies play a crucial role in the immune system’s defense mechanism.Acting as receptors or binding sites for certain immune system components, enzymes, and other crucial molecules.Maintaining the integrity of red blood cells.Type AB individuals tend to be rational and strong, with very little worry. The two types of antigen categories that classify blood types are ABO antigens and Rh antigens.Īntigens are either protein or sugar molecules that have these prime functions in the blood: Type B blood is often found in individuals who are outgoing, friendly and emotionally flexible.
Because of this, a person with any ABO and Rh blood type can receive O negative blood.īlood type is determined based on the antigens present on the surface of the red blood cells. O negative blood group is a type of blood group that does not have any of the major blood group antigens (A, B, or Rh). In emergency situations, sometimes patients are rushed to the hospital and there is no time to find out what blood type.
