In AB blood type, which antibodies are present in the plasma?

In this context, the antibodies present in plasma reflect the ABO antibodies a person has. People naturally develop antibodies against the A or B antigens they do not possess on their own red blood cells. Since someone with AB blood type has both A and B antigens on their red cells, their immune system recognizes A and B as self and does not produce antibodies against them. Therefore, AB plasma contains no anti-A or anti-B antibodies. Rh antibodies (anti-D) are a separate issue and are not automatically present unless someone has been sensitized to the D antigen. So the best answer is that AB plasma has no anti-A or anti-B antibodies.
