How is the compatibility test done between the blood of donor and recipient?
It is often assumed that if the donor and recipient belong to the same blood group their blood will be compatible. But in reality it is not so. Apart for A, B, and O group antigens there are many other blood group antigens on the Red cell surface of every human being. Under normal circumstances a full panel cross-match is done using GEL technology before every unit is released for transfusion. Only in the event of emergencies and if the consultant orders blood component without full panel cross-match, the same is issued with only ABOD compatibility testing.
