Detailed explanation-1: -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. That’s another reason it’s in such high demand.
Detailed explanation-2: -"Blood type and cross match” For example, a patient with blood group A can receive blood from a donor with blood group A (which lacks the B antigen) or blood group O (which lacks all ABO blood group antigens). However, they cannot receive blood from a donor with blood group B or AB (which both have the B antigen).
Detailed explanation-3: -But if you have type O blood, your red blood cells have no A or B markers. So: Your body will have both A and B antibodies and will therefore feel the need to defend itself against A, B, and AB blood. A person with O blood can only get a transfusion with O blood.
