Which Blood Type Is The Rarest In The World? Correct
AB- is considered the rarest blood type in the world. While O+, AB+, and O- are all common blood types, AB- is relatively rare, with a smaller percentage of the population possessing this blood type. Individuals with AB- blood can only receive blood from donors with AB- blood, making it a critical blood type for transfusions in cases where specific blood compatibility is required.
