Introduktion
The ABO blood group system is one of the most important blood group systems in human blood transfusion.

It is based on the presence or absence of certain antigens on the surface of red blood cells. These antigens are called A and B, and individuals can have one of four blood types: A, B, AB, or O.

The presence or absence of these antigens is determined by the genetic makeup of the individual.

Understanding one's blood type is important for blood transfusions, pregnancy, and other medical procedures.
