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.
Con: Type O negative carriers will have anti-A and anti-B antibodies against A B, Rh blood group antigens. Thus, a type O individuals can only accept type O blood. Introduction of other types of blood A, B, or AB may cause immune responses and ultimately, death! Type O negative is the rarest, which makes the supply of type O more scarce than other types. Pro: Type O negative is known as the universal donor type. This type of blood can be donated to anyone. Blood group O indivuduals do not have either A or B surface antigens on their red blood cells. Thus, one may donate and save many lives! (and you would really help people with blood O type!)
