Understanding ABO Blood Grouping Principles

ABO blood grouping is based on the presence or absence of two antigens—A and B—on the surface of red blood cells, and the corresponding antibodies (anti-A and anti-B) in the plasma. The test works by mixing the patient's red blood cells with known antisera:

• Agglutination with Anti-A → Blood type A
• Agglutination with Anti-B → Blood type B
• Agglutination with both → Blood type AB
• No agglutination → Blood type O

Reverse typing (plasma testing) is often performed to confirm results, especially in automated or high-volume settings.

Quality Note: Proper storage of antisera (typically 2–8°C), use of fresh blood samples, and adherence to expiration dates are crucial for reliable test outcomes in serological and control-based kits.
