1999-2008年贵州省碘缺乏病实验室外质控考核结果分析

Analysis of laboratory external quality control of iodine deficiency disorders in Guizhou province in 1999 -2008

目的 分析贵州省各级碘缺乏病（IDD）实验室外质控考核结果及网络运行情况,提高检查能力,为IDD流行病学监测和防治决策提供可靠的实验室质量保障.方法 对1999-2008年贵州省各级IDD实验室参加国家IDD参照实验室的外质控考核结果进行分析.结果 1999-2008年,贵州省省级实验室除2000年尿碘考核结果不合格外,其余9年均为合格;盐碘考核结果均为合格.贵州省市（州、地）级尿碘实验室反馈率,1999-2002年分别为88.9%（8/9）、66.7%（6/9）、77.8%（7/9）、66.7%（6/9）,2003-2008年稳定在100%（9/9）;合格率2007年达到100%外,其余9年在33.0%（3/9）～88.9%（8/9）.2000-2008年盐碘实验室反馈率均为100%（9/9）;2001-2003年合格率年分别为77.8%（7/9）、88.9%（8/9）、77.8%（7/9）,2007年合格率为88.9%（8/9）,其余5年为100%（9/9）.县级盐碘实验室参加外质控考核反馈率,2000-2003年分别为66.7%（20/30）、90.0%（27/30）、80.0%（24/30）、96.7%（29/30）,2006年为96.7%（29/30）,其余4年均为100%（30/30）;2000-2008年合格率在53.3%（16/30）～93.3%（28/30）.结论 各级实验室外质控检测结果的准确性以及网络的正常运行,与IDD实验室条件和检测技术水平有关,与相关部门和专业机构的重视程度有关.

Objective To analyze the assessment results of iodine deficiency disorders（IDD） External Quality Control Laboratories at all levels in Guizhou province and the network operation to further standardize and improve the laboratory, improve network performance, provide reliable laboratory quality assurance for epidemiological surveillance and control of IDD and reliable decision-making. Methods The results of different level of IDD labs in Guizhou that took part in the entire country＇s IDD lab exo-network quality control examination of 1999 - 2008, which organized by the nation iodine deficiency disorder reference lab were analyzed. Results In the past 10 years, except the provincial laboratory examination results of urinary iodine in 2000 was failed, the other results were all qualified in the rest 9 years;iodized salt examination results were qualified. The urinary iodine laboratory response rate of Guizhou provinces and municipalities（state, district）, from 1999 to 2002, were 88.9%（8/9）, 66.7%（6/9）, 77.8%（7/9）, 66.7%（6/9）, respectively, and the rate was stable at 100% from 2003 to 2008. Qualifying rate reached 100% in 2007, the remaining 9 years were 33.0%（3/9） - 88.9%（8/9）. The iodized salt laboratory response rates were 100%（9/9） in 2000 - 2008. The pass rates were 77.8%（7/9）, 88.9%（8/9）,77.8%（7/9） from 2001 to 2003, 88.9%（8/9） in 2007, and the remaining 5 years 100%. Response rate of iodized salt laboratory at the county level that participated in the External Quality Control were 66.7% （20/30）, 90.0%（27/30）, 80.0% （24/30）, 96.7% （29/30） from 2000 to 2003, respectively, and 2006 was 96.7% （29/30）, and the remaining four years were all 100% （30/30）. The pass rates in 2000 - 2008 were between 53.3% （16/30） -93.3%（28/30）. Conclusions The accuracy of test results of external quality controls and the normal operation of the network at all levels of laboratories is closely related to the IDD laboratory conditions, detection techniques, and the degree of attention of relevant departments and professional bodies.
