B+ is the 3rd blood group in the world. 610 million people worldwide are of blood group B+, or 9% of the world’s population. Only 7% of French people are positive group B. The characteristics of the blood group B+ are:
► Antigens: The red blood cells have antigens (protein) type B so B+ people can give them to people of blood groups B and AB because their plasma does not contain anti-B antibodies to destroy them.
► Rhesus: positive. Like any positive rhesus donor, red blood cells can be transfused to positive rhesus; In this case, this concerns the B+ and the AB+.
► Antibody: plasma is concentrated in anti-A antibodies So he “accepts” red blood cells of type O and B all rhesus.
