摘要
目的分析青海省省、市(州)、县(市、区)3级地方性氟中毒实验室砖茶氟外质控考核结果,评价各级实验室检测能力。方法采用Z分值法,对青海省2014-2020年参加砖茶氟外质控考核的省、市(州)、县(市、区)级实验室进行结果分析和评价,│Z│≤2为合格;2<│Z│<3为基本合格;│Z│≥3为不合格。结果从反馈情况看,青海省省、市(州)级实验室2014-2020年砖茶氟外质控反馈率均为100.00%;县(市、区)级实验室2014-2018年反馈率为100.00%,2019、2020年均有未反馈单位。从考核合格情况看,省、市(州)级实验室除2017年有1个单位不合格外,其余年份合格率均为100.00%;县(市、区)级实验室2014、2015、2016、2019年合格率均为100.00%,其余年份共有6个单位不合格。结论2014-2020年,青海省仍有部分地方性氟中毒实验室砖茶氟外质控考核结果不合格,今后将作为工作重点,加强人员培训,提高检测能力。
Objective To analyze the external quality control assessment results of fluoride in brick tea in the provincial,city(prefecture)and county(city,district)-level endemic fluorosis laboratories in Qinghai Province,and to evaluate the testing capabilities of laboratories at all levels.Methods The Z-score method was used to analyze and evaluate the results of provincial,city(prefecture)and county(city,district)-level laboratories that participated in the external quality control assessment of fluoride in brick tea in Qinghai Province from 2014 to 2020,and│Z│≤2 was qualified;2<│Z│<3 was basic qualified;│Z│≥3 was unqualified.Results From the feedback,the feedback rate of external quality control of fluoride in brick tea in provincial and city(prefecture)-level laboratories in Qinghai Province from 2014 to 2020 was 100.00%;the feedback rate of county(city,district)-level laboratories from 2014 to 2018 was 100.00%,and there were no feedback units in 2019 and 2020.From the assessment of qualification,the qualification rate of provincial,city(prefecture)-level laboratories was 100.00%in all other years except one unit failed in 2017;the qualification rate of county(city,district)-level laboratories was 100.00%in 2014,2015,2016 and 2019,and there were 6 unqualified units in other years.Conclusions From 2014 to 2020,some endemic fluorosis laboratories in Qinghai Province still fail to pass the external quality control assessment of fluoride in brick tea.In the future,it will be the focus of work to strengthen personnel training and improve the detection ability.
