blood group

A, B, or O

Blood group is a classification of blood based on the presence or absence of specific antigens on red blood cells.

The main system divides blood into types A, B, AB, and O, with positive or negative Rh factor.

Blood group matters for transfusions and organ transplants—incompatible types trigger dangerous immune reactions.
