目的了解不同实验室间杀菌效果评价结果的差异,提高消毒实验室技术水平。方法依据相同试验方法和条件,对不同实验室检测同一消毒剂杀菌效果进行评价与分析。结果在国内13个有资质的实验室共同对同一种含碘消毒剂、醋酸氯己定和乙醇复方消毒剂进行杀菌效果评价,结果对有效剂量报告的符合率为61.54%。存在的问题主要是有机干扰物和标准硬水的使用、样品稀释和实验条件控制不严格。结论国内消毒专业实验室对消毒产品检测结果偏离较大,需要加强统一培训。
Objective To understand the difference between the results of the evaluation of the bactericidal effect among different laboratories and to improve the technical level of the disinfection laboratory. Methods According to the same test methods and conditions, the sterilization effect of the same disinfectant in different laboratories was evaluated and analyzed. Results In the 13 laboratories in China, the same kind of iodine disinfectant, chlorhexidine acetate and ethanol compound disinfectant were evaluated for their bactericidal effect. The results showed that the coincidence rate of effective dose was 61.54%. The main problems are the use of organic interferences and standard hard water, and the control of sample dilution and experimental conditions is not strict. Conclusion Domestic disinfection professional laboratories deviate from the test results of disinfection products, and need to strengthen the unified training.
