The ABO blood group system is the most important blood type system (or blood group system) in human blood transfusion. It is named ABO and not ABC, because blood group O (or blood group zero in some countries) individuals do not have either A or B antigens on the surface of their RBCs, but their blood serum contains IgM anti-A antibodies and anti-B antibodies against the A and B blood group antigens. Therefore, a group O individual can receive blood only from a group O individual, but can donate blood to individuals of any ABO blood group (ie A, B, O or AB).

Understanding ABO Blood Grouping
The ABO blood grouping system is fundamental in immunohematology and is named based on the presence or absence of specific antigens on red blood cells (RBCs). The classification includes blood groups A, B, AB, and O. Here, “O” holds a significant meaning.
What "O" Represents
- The letter "O" in the ABO system indicates the absence of both A and B antigens on the surface of red blood cells.
- Individuals with blood type O do not express the A or B antigens, making them unique within this system.
Key Points About Blood Type O
- No Antigens Present:
- Blood type O is characterized by the lack of A and B antigens, which means that individuals with this blood type do not have these specific proteins on their RBCs.
- Antibodies Produced:
- People with blood type O produce both anti-A and anti-B antibodies in their plasma. This characteristic is crucial in blood transfusions as it determines compatibility.
- Universal Donor:
- Due to the absence of A and B antigens, blood type O is often referred to as the universal donor type. This means individuals with type O blood can donate to any other blood type without causing an immune reaction.
Conclusion
The naming of the ABO blood group system reflects the critical aspect of blood type O, which signifies no A or B antigens. This absence is crucial for understanding blood compatibility and transfusion practices in medicine.
