Answer 1

Routine pre-transfusion testing consists of ABO typing, Rh typing, and an antibody screen. The Direct Antiglobulin Test (DAT) is not part of routine pre-transfusion testing.

Step-by-step explanation:

Routine pre-transfusion testing consists of ABO typing, Rh typing, and an antibody screen. The Direct Antiglobulin Test (DAT) is not part of routine pre-transfusion testing.

During pre-transfusion testing, ABO typing is performed to determine the patient's blood type, Rh typing is done to determine if the patient is Rh positive or Rh negative, and an antibody screen is done to check for the presence of antibodies against antigens outside the ABO or Rh systems.
