      目的 分析实验室对饮用水中铜绿假单胞菌检测能力验证结果。方法 依据能力验证作业指导书并参照GB 4789.2-2016对样品进行稀释, 根据GB 8538-2016进行检测, 同时对可疑菌落使用API 20NE与VITEK2进行辅助鉴定。结果 样品18-N361、18-U838能力验证结果为满意。结论 通过此次能力验证, 解决了饮用水样品的稀释问题, 验证了API 20NE与VITEK2对可疑菌落进行辅助鉴定的准确性。VITEK2能缩短检验时间。

英文摘要:

      Objective To analyze the detection capability verification results of Pseudomonas aeruginosa in drinking water in laboratory. Methods The samples were tested according to GB 8538-2016, which were diluted according to the competency verification instruction and GB 4789.2-2016. The suspected colonies were identified by API 20NE and VITEK2. Results The capability verification results of 18-N361 and 18-U838 were satisfactory. Conclusion Through this capability verification, the dilution problem of drinking water samples is solved, and the accuracy of API 20NE and VITEK2 in assistant identification of suspected colonies is verified. VITEK2 can shorten the inspection time.
