RESUMO
OBJECTIVE To discuss the application of tachypleus amebocyte lysate test in transfusion reaction. METHODS Based on agglutination when tachypleus amebocyte lysate test encountered bacterial endotoxin, the quantity of the bacterial endotoxin was tested. RESULTS Twenty-three cases were analyzed with tachypleus amebocyte lysate test, the main reasons were excessive pyrogen, improper combined drug compatibility, excessive agents or unqualified pyrogen of the agent added, pollutions on transfusion devices and air in the treatment room, disobeying axenic operation rules, overlong drug dispensing, too fast transfusion speed, etc. CONCLUSIONS On prevention of transfusion reaction, all the axenic operation rules should be strictly followed, single dose transfusion, to reduce transfusion reaction.
