Every person has different blood group. Whenever a patient requires blood he must receive blood from same blood group donor and only after compatibility testing. Thus Blood group testing is one of the very first essential tests done in the blood bank. All the donor’s blood groups and atypical antibodies screenings are performed on fully automated blood grouping systems by Digast, France on Qualis Equipment.

Some infections like HIV, Hepatitis, Malaria, Syphilis can be transmitted to patient through blood. Hence after collection every donor’s blood is tested for transfusion transmitted infections (TTI). It is only after this testing; blood can be used for patient. This avoids spread of these infections. To reduce chances of finding these infections blood is collected from voluntary blood donors only.
