blood types

A, B, O, AB

Blood types are categories for classifying human blood based on the presence or absence of certain antigens on red blood cells.

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

Blood type matters for transfusions and organ transplants—mismatched types can trigger fatal immune reactions.
