Difference between O+ and O- Blood Group. Key difference: The blood groups O+ and O- are universal donors. The only difference is in the recipients to whom the blood is transfused; O+ can be transfused to any positive blood groups, whereas O- is transfused to both positive as well as negative blood groups. O+ blood group is a common blood group among most of the people.
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!)
