Blood Group

The most well-known and medically important blood types are in the ABO group. All humans and many other primates can be typed for the ABO blood group. There are four principal types: A, B, AB, and O. There are two antigens and two antibodies that are mostly responsible for the ABO types.

Rh blood group system : The Rh system is the second most significant blood-group system in human-blood transfusion with currently 50 antigens. The most significant Rh antigen is the D antigen, because it is the most likely to provoke an immune system response of the five main Rh antigens .

We can say : The presence or absence of D Ag determines if the person is Rh+ or Rh-

Possible subsequent pregnancies Rh antibodies Result from the exposure to Rh antigens Bind at 37°C Anti-Rh+ antibodies Possible subsequent pregnancies Mother makes anti-Rh+ antibodies.
