Rationale: Grouping and crossmatching is the procedure performed prior to a blood transfusion to determine the blood type and identify any potential incompatibilities between the donor and recipient. This process involves testing the recipient's blood for ABO and Rh antigens and crossmatching it with the donor's blood to ensure compatibility and prevent adverse reactions during the transfusion. Complete blood count, D-dimer test, and blood clotting test are other laboratory tests that serve different purposes and are not specifically done to detect incompatibilities prior to blood transfusion.
