Dear Omar The U-shaped plate method is fully automated and involves the addition of plasma and RBCs, centrifugation, incubation with constant shaking, and final observation and interpretation ( 22 ). Advantages to using this method include fewer trapped air bubbles, less chance of sample loss, less chance of contaminating the mounting medium and less waste of mounting medium. Among these, ABO blood grouping system is the most important system for screening, transfusion and transplantation practice today. These techniques have advantages and disadvantages inherent to them.
