摘　　要：目的:通过对苏州市范围内的快速检验室进行盲样考核,并结合现场调查,了解目前苏州市快速检验室的能力水平。方法:在苏州市的十个县(市、区)内,随机选择了50家农贸市场和9家批发市场,发放了质控样品进行盲样考核,分别考核3项和5项检测项目。每个项目都发放了1个阴性样品和2个阳性样品(分别为1倍和1.5倍的检出限)。市场快速检验室需要在48小时内反馈快速检验结果,随后进行对比分析。结果:本次考核中,农贸市场的通过率为38%,批发市场的通过率为100%。有37家农贸市场和9家批发市场的快速检验室能够覆盖本次考核中的所有项目,但是只有很少一部分项目的结果被评为“符合”,其他项目则出现了较多的假阴性结果。在所有考核项目中,对灭多威和沙丁胺醇的考核结果最好,而对甲醛的考核结果较差。结论:通过本次快速检验盲样考核,了解到苏州市目前快速检验室在能力建设方面存在问题,并针对性地提出了相应的建议措施。希望这些建议可以为苏州市快速检验的发展和食品监管提供参考和借鉴。Objective:This paper aimed to understand the capability of rapid test laboratories in Suzhou through blind sample assessment and field investigation.Methods:A total of 50 agricultural markets and 9 wholesale markets were randomly selected from various counties,cities,and districts in Suzhou to check 3 and 5 test items respectively.Each laboratory in the market received one negative sample and two positive samples,with concentrations set at 1 and 1.5 times of the detection limit.The rapid test laboratories in the market had to give feedback on the results within 48 hours for comparative analysis.Results:The passing rate for agricultural markets was 38%,while the wholesale markets achieved a 100%passing rate.The rapid test laboratories in 37 agricultural markets and 9 wholesale markets could accurately detect all the examined items,but only a small number of their results were in line with the expected outcomes,with a significant number of false negatives.Among the examined items,the results of methomyl and salbutamol were the best,while the results of formaldehyde were the worst.Conclusion:This blind sample assessment points out the problems in capability construction of rapid test laboratories in Suzhou.Corresponding measures are put forward,aiming to improve the development of rapid test technologies in Suzhou and provide reference for food supervision.
