2005～2010年青岛市疾病控制实验室比对/能力验证状况分析

Analysis on Interlaboratory Comparisons/Laboratory Proficiency Testing of Disease Control and Prevention Units,Qingdao City,2005-2010

[目的]分析青岛市疾病控制实验室比对/能力验证状况,指导实验室有效实施质量控制,为能力验证组织方提供参考。[方法]对2005～2010年青岛市疾病控制实验室参加国家认证认可机构和上级业务部门组织能力验证资料进行分析。[结果]参加国家认证认可部门组织能力验证多,能力验证领域分布不均匀,参加食品及相关产品、水及涉水产品能力验证多;其中对食品添加剂检测最多,其次为重金属检测;疾病控制类产品参加能力验证相对少。实验室能力验证基本覆盖主要化学分析方法,使用原子吸收分析最多,其次为分光光度和气相色谱检测技术,再次为离子色谱和液相色谱分析,重量分析和滴定分析及其他小型设备使用较少。[结论]关注能力验证领域分布均匀性,加强实验室资金投入和参加活动主动性,进一步提高检测技术手段。

[Objective]To analyze the results of interlaboratory comparisons/laboratory proficiency testing, guide the quality control of the laboratory, so as to provide reference for the organization, l-Methods]Data of interlaboratory compari- sons/laboratory proficiency testing organized by those certification and accreditation bodies and higher department from 2005 to 2010 were analyzed. [Results]There was more participation of laboratory proficiency testing of those certification and accreditation bodies than of higher department. The participation category was uneven and mainly included the foods and related products, water and related products. The maximum participation was food additives, and the second was heavy metals. The participation of disease control related samples was the least. The laboratory proficiency testing covered most of the chemical analytical methods. The AAS was the most commonly used instrument method, the second was spectro- photometry and GC, the third was IC and HPLC. The gravimetric analysis and titration analysis were less used. [Conclusion]Close attention should be paid to the uneven participation category of laboratory proficiency testing, the financial in- put should be strengthened and the initiative of participation should be enhanced,so as to improve the detection ability of laboratory further.
