O+ is the 1st blood group in the world. 38% of the world’s population is o positive. Here are the characteristics of the blood group o+
► No antigen on its surface: The B blood group O does not have any protein on the surface of its red blood cells, so they can be transfused to all blood groups without problem.
► Rhesus: positive. Negative rhesus people cannot receive positive rhesus blood. Only individuals A+, B+, AB+ and O+ can receive these red blood cells.
► Antibodies: The plasma that makes up the blood includes anti-end and anti-B antibodies in groups O, all rhesus combined. In the presence of red blood cells of blood groups A, B and AB, antibodies destroy them as if they attacked a virus. We are talking about hemolysis. O+ people can only be transfused with red blood cells O+ and O-.
