Erythrocytes have characteristics cell-surface proteins (antigens). Antigens are macromolecules that are foreign to the host organism and trigger an immune response. The two major groups of red blood cell antigens are the ABO group and the Rh factor.
1. ABO group:
There are four ABO blood groups A, B, AB and O; see table below:
Blood Antigen Antibodies
A A anti-B
B B anti-A
AB A and B none
O none anti-A, and anti-B
