Detailed explanation-1: -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-2: -People with A positive blood can receive donations from: A positive donors. A negative donors. O negative donors.
Detailed explanation-3: -For example, if someone with group B blood is given group A blood, their anti-A antibodies will attack the group A cells. This is why group A blood must never be given to someone who has group B blood and vice versa. As group O red blood cells do not have any A or B antigens, it can safely be given to any other group.
