Detailed explanation-1: -Answer From Rajiv K. Pruthi, M.B.B.S. For emergency transfusions, blood group type O negative blood is the variety of blood that has the lowest risk of causing serious reactions for most people who receive it. Because of this, it’s sometimes called the universal blood donor type.
Detailed explanation-2: -O positive red blood cells are not universally compatible to all types, but they are compatible to any red blood cells that are positive (A+, B+, O+, AB+). Over 80% of the population has a positive blood type and can receive O positive blood.
Detailed explanation-3: -Blood group O can be donated to any of the other blood groups as it has no antigens, to initiate an antibody reaction. Thus blood group O is the universal donor.
