目的了解我国自身抗体检测的现状,促进自身抗体检测的水平。方法以自愿报名方式确定参与单位。质控项目包括抗核抗体(ANA)、抗双链DNA抗体(抗dsDNA抗体)、抗可提取核抗原(ENA)抗体、抗线粒体抗体(AMA)、抗平滑肌抗体(ASMA)5项,共12份标本。标本发放及结果分析采用双盲操作。结果ANA正确率85.4%;抗dsDNA抗体正确率81.8%;抗ENA抗体正确率36.9%;AMA正确率66.7%、ASMA正确率50%。结论与第一次质控相比,总的来说各项抗体的检测水平有一定提高。
Objective To understand the current status of autoantibodies detection in our country and to promote the detection of autoantibodies. Methods to determine the voluntary registration of participating units. Quality control programs included ANA, anti-dsDNA (anti-dsDNA), anti-extractable nuclear antigen (ENA), anti-mitochondrial antibody (AMA) and anti-smooth muscle antibody (ASMA) A copy of the specimen. Specimen release and results analysis using double-blind operation. Results The correct rate of ANA was 85.4%, the correct rate of anti-dsDNA antibody was 81.8%, the correct rate of anti-ENA antibody was 36.9%, the correct rate of AMA was 66.7% and the correct rate of ASMA was 50%. Conclusions Compared with the first quality control, the detection level of all the antibodies is generally improved.
