保健食品中格列本脲含量测定的能力验证研究

目的设计组织保健食品中格列本脲含量测定能力验证项目,评价实验室检测保健食品中格列本脲的技术能力和水平。方法对考核样品通过实施能力验证计划,来自27个省(自治区)、直辖市80家实验室的测定结果进行稳健统计分析,通过稳健Z比分数评价实验室检测能力。结果考核样品中的格列本脲在P0.05显著水平时是均匀的,且在整个计划周期内稳定,满足能力验证的要求。在80家参加实验室中,满意结果数为68家,满意率为85.0%;可疑结果数为6家,可疑率为7.5%;不满意结果数为6家,不满意率为7.5%。结论多数参加的实验室检测能力结果满意,表明保健食品中格列本脲检测水平总体良好。

Study on the capability verification of determination of glibenclamide in health food

Objective To design and organize a project to verify the determination ability of glibenclamide in health food and to evaluate the technical ability and level of glibenclamide in health food. Methods Examining sample was conducted through the implementation of the plan of ability test and verify, 80 laboratories from 27 provinces and the autonomous region were measured and the results were conducted for robust statistical analysis, robust Z ratio fraction was used for laboratory testing capability. Results The glibenclamide in the test samples was uniform at the significant level of P < 0.05 and stable throughout the planning period, meeting the requirements of ability verification. Among the 80 participating laboratories, 68 were satisfied with the results, and the satisfaction rate was 85.0%. The number of suspicious results was 6, and the suspicious rate was 7.5%. The number of dissatisfied results was 6, and the dissatisfaction rate was 7.5%. Conclusion The majority of the participant laboratories passed the test with satisfactory results, indicating that the determination of glibenclamide in health food showed a overall good level.
