ABO and Rh systems
ABO antigens and naturally occurring antibodies can cause severe incompatibility; Rh and other blood-group systems also matter.
Antibody screening
Validated tests identify clinically relevant alloantibodies and direct selection of antigen-negative units when appropriate.
Compatibility testing
Testing follows established protocols that integrate patient identification, historical antibodies and current specimen results.
Transfusion reactions
Hemolytic, febrile, allergic and other reactions require immediate local safety procedures and structured laboratory investigation.
