全国2009年沙眼衣原体抗原检测室间质量评价

A nationwide external quality assessment of Chlamydia trachomatis testing in 2009

目的评价全国性病实验室检测沙眼衣原体抗原的能力。方法质控样品由中国疾病预防控制中心(CDC)性病控制中心参比实验室统一配制,通过邮寄方式发放至各参评实验室。各实验室在规定时间内进行检测,并将检测结果回报性病控制中心。结果 2009年参加质评活动的单位共140家,其中省级CDC中心实验室/皮肤病防治研究所30家;国家级性病监测点81家;自愿参加的各级皮肤性病防治机构29家。在140家参评单位中,70.0%(98/140)性病实验室回报结果与预期结果完全相符,考核成绩为优秀;22.14%(31/140)考核成绩为合格;7.14%(10/140)考核成绩为一般;0.71%(1/140)考核成绩为不合格。2009年沙眼衣原体检测室间质评考核成绩平均为92.14分,合格率为92.14%。结论省级中心实验室和自愿参加的各级性病实验室CT检测能力普遍较高,但少数监测点实验室存在试验操作失误、检测方法选择错误及试剂质量等问题,检测水平有待进一步提高。

Objective To assess the capability of Chlamydia trachomatis（CT） testing among all-level laboratories of sexually transmitted diseases（STD） in China.Method Quality control samples were sent to laboratories of different levels including provincial central lab（30） and national surveillance sites（81）,as well as some different-level laboratories which participated in the assessment voluntarily（29）.The results of the testing with quality control samples were mailed by the partcipating laboratories to the National Center for STD Control for final analysis and then the scores of the quality control testing were returned to respective laboratories.Result Based on their approximation to pre-determined standards,the scores of 140 laboratories were stratified into four groups： excellent（70%）,qualified（22.14%）,general（7.14%） and unqualified（0.71%）.And the rates of excellent and qualified laboratories among provincial central lab and different-level laboratories participating voluntarily as well as some national surveillance sites were 100%,93.10% and 88.89% respectively.Conclusion The provinccial central lab and different-level laboratories participating voluntarily had gained higher scores,but some national surveillance sites had lower scores and so should improve their CT testing capacity.
