摘　　要：目的：初步建立贵州省泌尿生殖道分泌物常规检验室间质量评价（ EQA）体系，以提高其整体检测水平。方法2009至2011年，每年在贵州全省范围内抽取50家以上不同等级医院的临床检验实验室作为参评单位。每年开展两次EQA，每次选取瑞氏和（或）革兰染色良好的泌尿生殖道分泌物涂片5张（相当于5个批号质评品）直接和（或）彩图发给参评实验室进行检测，并对各个实验室的回报结果进行分析评价，以符合率≥80％判为合格。结果2009至2011年EQA参评单位从55家上升至96家，总平均回报率＞80％。3年6次EQA 结果平均符合率＜80％的有球菌4次（73．7％、77．8％、61．1％、77．1％），杆菌2次（75．6％、79．3％），球杆菌2次（64．3％、52．1％），滴虫（79．7％）、上皮细胞（76．1％）、中性粒细胞（75．7％）及清洁度（71．3％）各1次。6次30个质评品中有6个批号（占20．0％）的平均符合率＜80％；30个质评品11个EQA项目分别有1～15个批号的平均符合率＜80％即不合格。总平均符合率以可疑淋球菌为最高（94．2％），以球菌及球杆菌为最低即未达到合格（各占77．0％、75．2％）。结论在一定范围内开展EQA活动并取得良好效果，参评单位明显增加，总的参评成绩呈上升趋势，在一定程度和范围内增强了检验人员的质量意识；初步建立了贵州省泌尿生殖道分泌物常规检验的EQA体系，为临床实验室和上级机构提供了室内质量控制和EQA的一个参考模式。Objective To establish an external quality assessment （ EQA） system of genitourinary tract secretions routine testing in Guizhou Province and improve the overall testing level.Methods From 2009 to 2011, more than 50 clinical laboratories in different grade hospitals from Guizhou Province were enrolled as participating units every year.EQA was carried out twice a year.Each time, five slides of high quality Wright′s or Gram stain smear of the genitourinary tract secretions or photographs obtained from these smears were selected to send to the participating laboratories for testing, and the feedback results from each laboratory were analyzed.The qualification was judged by the coincidence rate equal to or more than 80%. The average coincidence rates of each time and each year were statistically analyzed by Chi-squared test. Results From 2009 to 2011, the number of EQA participating units increased from 55 to 96, with an average return rate of 〉80%.Coincidence rates 〈80%of the 6 EQA results in the 3 years were as follow：four times for coccobacteria （73.7%,77.8%,61.1%,77.1%）, twice for bacillus （75.6%,79.3%） and coccobacillus （64.3%,52.1%）, once for infusorian （79.7%）, epithelial cells （76.1%）, neutropenia nbsp;（75.7%） and cleanliness （71.3%）.There were six batches of 30 quality assessment controls （accounting for 20.0%） in the six EQAs had the coincidence rate of 〈80%.Eleven items of 30 quality assessment controls with 1 to 15 batches were unqualified （ average coincidence rate of〈80%） respectively.The item with the highest total average coincidence rate was suspected gonococcus （94.2%）, and two items with the lowest total average coincidence rates were coccus and coccobacillus （ 77.0%, 75.2%, respectively ） . Conclusions This EQA program carried out within a certain range of clinical laboratories achieved good results：participating units increased significantly;the total score of all the items showed an obviously upward trend;the quality awareness of clin
