用鲎试剂(TAL)直接检测20％甘露醇注射液细菌内毒素出现假阳性,有报道,可用稀释法排除干扰。笔者实验后认为、用弃G因子鲎试剂(Es—Test)直接检测该射液细菌内毒素的方法优于稀释法。1 仪器与试剂 电热恒温水浴箱(北京医疗器械厂);20％甘露醇注射液(龙口矿务局中心医院);TAL(0.1Eu/ml),Es—Test(0.5Eu/ml),细菌内毒素工作标准品(福建厦门鲎试剂厂) Direct detection of bacterial endotoxin in 20% mannitol injection by limulus reagent (TAL) shows false positives. It has been reported that interference can be removed by dilution. After the experiment, the author thinks that the method of using the G-factor reagent (Es-Test) to directly detect the bacterial endotoxin of the injection is better than the dilution method. 1 instruments and reagents electric heated water bath (Beijing Medical Equipment Factory); 20% mannitol injection (Longkou Mines Central Hospital); TAL (0.1Eu / ml), Es-Test Toxin standard work (Fujian 鲎 Reagent Factory)
