Quick Answer
AB-negative is the rarest ABO blood type, found in less than 1 % of the global population.
The Full Story
Among the eight common ABO/Rh blood types, AB-negative is the rarest, present in less than 1 % of people worldwide. B-negative (about 1.5 %) and AB-positive (about 3.4 %) are also uncommon. Blood type distribution varies by ethnicity and region — for example, type B is more common in Asia, while type O is most common globally (about 44 %). Beyond ABO and Rh, over 300 other blood group antigens exist; some extremely rare types, like Rh-null ("golden blood"), have been identified in fewer than 50 people ever.
Key Facts
1.Only about 0.6 % of people have AB-negative blood.
2.Rh-null blood can be donated to anyone with a rare Rh type but is extremely scarce.
3.Type O-negative is the universal red cell donor; AB-positive is the universal plasma donor.
