This because AB- type has both A and B antigens but has no Rh antigen. 2. AB Negative type is not a great donor. Again due to absence of the Rh antigen but presence of A and B antigens, the AB- blood type donor can only donate blood to AB- and AB+ blood type individuals.
A and B are antigens that are on the surface of red blood cells. People have one, both, or none. If you don't naturally produce the antigen, your body's white blood cells will attack and destroy red blood cells that carry them. So if a person with type A blood is injected with type B blood, the body of that person will attack the type-B blood cells. A person with AB positive blood is a universal receiver, because they already produce all of the normal antigens present on red blood cells. So a AB+ person's body will not attack red blood cells that carry some, all, or none of the antigens. Likewise, O- is called the universal donor, because it lacks all antigens.
