Under most cases the donor blood has already been typed and tested for HIV Hepatitis and other disqualifying conditions.
The recipient (person getting the blood) is normally typed to insure the blood is a match.
Except in the case of trauma- here the most common given blood is O neg where absolutely needed and there is a protocol to follow. If a person where Type A and they received type B blood the results would defiantly not be pretty. But O neg while there is some minimum amount of risk is the best and safest bet in these cases.

Blood group is necessarily tested at the time of blood trnasfusion unless the donr is sur of the group to which his blood bleongs .Because the trnasfusion of the worng group of blood is worse than non-transfusaion of blood. When some the group fo the blood that is supplied for trnasfusion is known or the donar gies information of the group he belongs , theblood is not testred in an emergence . Wrong transfusion occurs more due to misinformation and negligiance .

The blood was grouped for ABO and Rh, given tests for HIV and hepatitis and syphilis. When a transfusion situation arises, the patient is typed and crossmatched with a suitable unit.
