HIV抗体可疑标本实验室检测结果分析

Analysis on Laboratory Surveillance of HIV Antibody Suspected Samples

目的探讨艾滋病初筛实验室质量管理及初筛实验与确认实验的关系,为进一步做好艾滋病初筛实验室工作提供依据。方法对2003、2004年HIV抗体可疑标本初筛实验和确认实验结果进行分析。结果2004年初筛阳性率比2003年增高;两种国产试剂初筛实验一阴一阳标本确认阳性率0%,双阳标本确认阳性率80.2%;两种初筛实验样品光密度/临界值(S/CO)≥6的标本确认阳性率为100.0%。结论艾滋病初筛实验室应严格管理:在市级疾病预防控制中心艾滋病初筛实验室两种国产试剂初筛S/CO≥6标本,可以上报疫情,尽快送省疾病预防控制中心确认。

Objective To study the quality management of AIDS primary screening lab and the relation between the primary screening test and the reconfirmation test. Methods The result of 2003、2004 HIV antibody suspected samples, between primary screening test and reconfirmation test were analyzed. Results The positive rate of the 2004 primary screening test was higher than that of 2003; the confirmed positive rate of the samples whose primary screening test results were one positive and one negative by two domestic reagents was zero; the samples that both positive was 80.2%; the confirmed positive rate of the samples whose primary screening test S/CO≥6 with the two domestic reagents was 100%. Conclusion The quality management of AIDS primary screening lab should be strict; for those samples whose primary screening test S/CO≥6 with the two domestic reagents by municipal CDC could be reported and the samples should be sent to provincial CDC for confirmation in time.
