Are antibodies removed before blood transfusion I am an O blood group person meaning, I can donate my blood to all as I don't have any Antigen A and B. But my body does contain antibodies A and B right? If they were along with the donor blood, wouldn't they cause clotting with the recipients blood? We spent a whole period over this. My teacher said they probably remove the antibody before transfusion, but I couldn't find much info on that. I postulated that these antibodies can not work outside the donor body for some reason. Thanks for the help

I quote from the below.

"Red blood cell incompatibility may also occur when the patient's RBC antigens are attacked by antibodies from the donor's plasma. This tends to be a minor problem because of the small amount of antibody present in the donated plasma, which is further diluted on transfusion into the recipient's circulation."

I dont think the antibodies are removed, but in countries with a good medical system I believe the matching blood type is always used.
