1, Moreschi describes the antiglobulin reaction.

2, METHODS: Antiglobulin test (AGT) of drug simulated in vitro were performed with hemo immunology.

3, The causes of transfusion reaction was detected by antiglobulin test of Coombs.

4, The antiglobulin is a direct way of visualizing an antigen-antibody reaction that has taken place but is not directly visible.

5, Methods: Employed irregular antibody screening on 693 samples with microcolumn gel agglutination assay, and identified with enzyme and antiglobulin method to observe the positive rate.
