Antigen identification antigrams decode antibody reactions in blood transfusions, ensuring safe blood selection by identifying compatible red blood cells that lack the antigen targeted by the recipient’s antibody.

Incubate patient serum with panel RBCs, check for agglutination! Enzymes & antiglobulin tests may be used to reveal hidden antibody reactions.

Antibody screening mixes patient plasma with red blood cells to detect unexpected antibodies. Agglutination indicates possible antibodies, requiring further identification for safe blood transfusions
