Red blood cell (RBC) antibodies

Red blood cell (RBC) antibodies are proteins in the blood that can recognize and attack foreign red blood cells, such as those from a different blood type. They develop when the immune system encounters incompatible blood, often during transfusions or pregnancy. These antibodies can cause immune reactions like hemolytic transfusion reactions or hemolytic disease in newborns, where red blood cells are destroyed. Understanding RBC antibodies is important for ensuring safe blood transfusions and managing pregnancies, preventing immune-related complications by matching donor blood and monitoring sensitive pregnancies.
