ABO Blood System

The ABO blood system is the blood system that most people know about. O negative blood is considered to be the blood type that nearly everyone can receive in trauma situations. Matching blood to individuals in need of a blood transfusion is a complicated process. The transfusion medicine department has many procedures that are followed to ensure the most compatible blood products are given to a patient. There are many other blood group systems that are tested for in the transfusion medicine department. Individuals can produce antibodies to these other blood group systems as well.

Answer and Explanation: 1

A person with type A positive blood will not have antibodies to the A antigen because people do not develop antibodies against their own blood type. If individuals produced antibodies against their own blood type they would react with their own blood and most likely cause their own death.

When looking at the ABO blood system, individuals produce naturally occurring antibodies against the blood type that they do not have. For example, a type A individual produces type B antibodies, while a type B individual produces type A antibodies. Type O individuals produce antibodies against both type A and type B blood.
