      目的 探讨我国快检方法的评价管理模式及应用效果。方法 在梳理和比较国内外相关食品快速检测方法和产品的技术评价规范及标准的基础上, 采用贝叶斯推断, 将快速检测所获得的数据与食品安全监管中所使用的实验室方法检测数据相结合。结果 基于贝叶斯推断, 将快速检测筛查和实验室确证相关联进行评价, 能够在较大程度上提高快检方法的理论有效性。有必要将快速检测与实验室确证检测相结合, 有针对性地设定相应的快检检出限值及假阳/阴性率, 提高检测结果的准确性。结论 在实际应用中, 应结合实验室方法检测数据对快速检测所获得的筛查结果进行评估, 以提高风险筛查效能。在此基础上, 有必要进一步规范食品快速检测方法及产品的评价标准, 完善科学的评价方法及评价体系, 以保障我国食品安全及快速检测行业的健康发展。

英文摘要:

      Objective To investigate the evaluation management mode and application effect of fast inspection method in China. Methods On the basis of combing and comparing the relevant food rapid detection methods and product technical evaluation specifications and standards at home and abroad, using Bayesian inference, the data obtained from rapid test with the test data of laboratory method used in food safety supervision was combined. Results Based on Bayesian inference, the theoretical validity of the rapid detection method could be improved to a great extent by combining the rapid detection with laboratory confirmation. It is suggested that the rapid detection should be combined with laboratory confirmatory testing, and the corresponding detection limit and false positive/negative rate should be set to improve the accuracy of the test results. Conclusion In practical application, the screening results obtained by rapid detection should be evaluated in combination with the laboratory method test data, so as to improve the risk screening. On this basis, it is necessary to further standardize the evaluation standards of food rapid detection methods and product, and improve the scientific evaluation methods and evaluation system, so as to ensure the food safety and healthy development of rapid detection industry in China.
