摘　　要：目的评价辽宁省各级疾病预防控制（简称疾控）机构实验室水氟检测能力，提高检测质量。方法利用Z比分数值对2016年辽宁省66个疾控机构实验室水氟外质控考核结果进行分析和评价，并利用Youden图查找可能离群的实验室。z比分数法判定标准：/z/≤2为满意；2〈/z/〈3为合格，但提示存在问题．需及时查找误差原因；/z/33为不满意。结果z比分值评价结果显示，66个实验室/z/均≤l，检查结果满意，满意率为100．0％（66／66）；Youden图结果显示，共计有4个点在椭圆外，占6．1％（4／66），提示这4个实验室的检测结果出现了离群，需要做进一步的复核。结论辽宁省的疾控实验室水氟检测能力符合标准。个别实验室还需提高检测质量。实验室内部质量控制至关重要，各级疾控机构仍需持续提高实验室检测能力。Objective To evaluate the detection capability in determining water fluoride at center for disease control and prevention （CDC） of Liaoning Province, and to promote the improvement of detection quality. Methods The detection results of the external quality assessment of fluoride in water from 66 CDC labs in Liaoning Province in 2016 were analyzed by using standard Z score. The potential oufliers were determined by Youden plot. The determine standard of the Z score： /z/ ≤ 2 was satisfacted; 2 〈/z/ 〈 3 was qualified, but suggesting there was a problem, need to find the cause of the error;/z/ 〉 3 was not satisfied. Results According to the results of standard Z score, there were 66 labs satisfacted, the satisfacted rate was 100.0% （66/66）. According to the Youden plot, there were 4 possible outliers （6.1%, 4/66） which need to be rechecked. Conclusions The capability in determining water fluoride at CDC of Liaoning Province meet the standards, but individual laboratories need to improve the quality of testing. The internal quality control of the laboratory is very important. All CDCs should improve the detection capability continuously.
