I HAVE HAD TESTS NEEDED AND AM AWAITING RESULTS. i WONDERED ABOUT ANTIBODIES IN MY BLOOD AS I HAD TO HAVE INJECTION WHEN I HAD TWINS AS THEY WERE MY SECOND BABIES.SHOULD I BE LOOKING FOR ANY SYMPTOMS ?
Hello and welcome to Chat Doctor, The AB + blood group suggests presence of both AB antigen in and absence of Rh factor in your blood. Reactions can occur when there is mismatched blood transfusion and a genus with different blood group. In case the fetus has different blood group, anti D immunoglobulin factor is given within 72 hours of delivery. As you have mentioned you have had the antiserum at the time of delivery. Mixing of blood (as you have mentioned) does not cause transfusion reaction. So, there is nothing to worry about the reaction. However, there is risk of reaction in subsequent pregnancies in which case you have to take anti D immunoglobulin again. Thanks and take care Chat Doctor.
