目的 :评价艾滋病毒检测初筛实验室的检测质量 ,促进质控水平的提高。方法 :用包括HIV抗体阳性、弱阳性和阴性共 2 0份考评血清对 53个医疗防疫单位的艾滋病毒检测初筛实验室进行现场测试。结果 :35个实验室检测结果完全正确 ,17个实验室出现了不同程度的假阴性结果 ,近 1/ 3的实验室检测弱阳性标本的S/CO值低于质控标准的 95%可信限以下。结论 :敏感性达不到标定的范围是HIV检测存在的主要问题。未严格遵守艾滋病毒检测工作规范 ,技术操作水平低是出现问题的主要原因。
Objective: To evaluate the testing quality of HIV testing screening laboratories and to promote the improvement of quality control. Methods: Field tests were conducted on HIV testing screening laboratories of 53 medical and epidemic prevention units with a total of 20 test sera including HIV antibody positive, weak positive and negative sera. Results: The results of 35 laboratory tests were completely correct. 17 laboratories showed varying degrees of false-negative results. Nearly one-third of the laboratory-tested weakly positive specimens had S / CO values below 95% of the control standard Limited below. CONCLUSIONS: The extent to which sensitivity falls short of the calibration is a major problem with HIV testing. Not strictly abide by HIV testing norms, low level of technical operation is the main reason for problems.
