    ABO blood typing

    Advertisements



    hi ,
    i am confused, mayb cuz am tired.
    so we know that group 0 is universal donor, ok.
    now group 0 has A and B antibodies.
    say we are giving group 0 blood to a group A recipient who has A antigen.
    now why doesnt the blood group 0 antibody attack the A antigen in the recipient blood group A

    only red blood cells

    You must notice that AB0 antigens are on the cell membrane of red blood cells and that the respective antibodies are in the plasma. When a person receives blood because he is having surgery for example, they only give him red blood cells. So letīs think the following: a person with group A (john) has antigenA on red blood cells and antiB antibodies in his plasma. A person with group 0 (mary) has antiA and antiB antibodies in his plasma and has no antigens on red blood cells. So if JOhn receives red blood cells from mary, he will NOT be receiving antiA nor antiB antibodies and therefore there wont be hemolysis
