2012年柳州市HIV抗体筛查实验室比对结果分析

Analysising the result between HIV antibody screening laboratories in Liuzhou

目的通过组织柳州市县HIV抗体筛查实验室进行一次室间比对,提高各个HIV抗体筛查实验室检测能力,减少其在日常检测中的差错。方法通过下发盲样的方式,共36家HIV抗体筛查实验室,均采用ELISA的方法对考核标本(QC001、QC002、QC003、QC004、QC005)进行单独检测,并及时反馈结果。结果 36家实验室对5个盲样的检测结果显示,除了QC005的正确率为97.2%外,其他几个盲样的考评正确率均达100.0%,分析定量检测结果显示CV值波动较大,只有个别盲样CV值能控制在25%内。结论全市HIV抗体筛查实验室建设已经初具规模并且有良好的检测能力,但质量控制仍需加强。

Objective To evaluate the level of test and standardize management in HIV antibody screening laboratories in Liuzhou city in order to promote them to improve their whole test ability and reduce the error in the routine detection. Methods Having 36 HIV antibody sereening laboratories joined the examination. Them using the method of ELISA to detect these blind samples （QC001, QC002, QC003, QC004, QC005）, then returned the result to us. Result The results of blind samples showed that the coincidence rates all were 100% but the QC005 was 97.2%. Analysising the quantitative testing results showed that CV value was fluetuant greatly, shows that the HIV antibody screening laboratory quality control should be improved. Conclusion The overall quality of the HIV screening laboratories in Liuzhou city is satifactory but need to enhance in the quality control.
