目的对北京地区无偿献血人群人类免疫缺陷病毒(HIV)筛查结果进行分析。方法分析本站2014年8月1日至2016年6月30日血液HIV初筛及确证数据。结果 ELISA检测双试剂阳性样本的ELISA筛查S/CO值均>6,确证阳性率达92.0%;ELISA检测单试剂阳性样本确证无阳性,不确定占32.4%,确证阴性占67.6%。不确定及阴性样本的两种试剂S/CO值大部分<6。索林HIV试剂初筛阳性率为0.21%,确证阳性率为20.5%,确证不确定率为26.5%,确证阴性率为53.0%,初筛假阳性率为0.11%;伯乐HIV试剂初筛阳性率为0.11%,确证阳性率为38.8%,确证不确定率为21.9%,确证阴性率为39.3%,初筛假阳性率为0.04%。结论北京地区无偿献血者HIV初筛阳性样本的确证阳性率与其他地区数据有所不同。本研究所使用2种ELISA试剂检测结果无统计学差异。
Objective To analyze the result of human immunodeficiency virus (HIV) screening in unpaid blood donors in Beijing. Methods The data of blood HIV screening and confirmation from August 1, 2014 to June 30, 2016 were analyzed. Results The S / CO values of all ELISA positive ELISA samples were all> 6, and the positive rate was 92.0%. The ELISA positive samples were confirmed to be 32.4% uncertain and 67.6% negative. Uncertain and negative samples of the two reagents S / CO value most <6. The positive rate of Sorin HIV reagent was 0.21%, the positive rate was 20.5%, the positive rate was 26.5%, the positive rate was 53.0%, the false positive rate was 0.11% Was 0.11%. The positive rate was 38.8%. The confirmation uncertainty rate was 21.9%. The positive rate was 39.3%. The false positive rate was 0.04%. Conclusion The positive rate of positive HIV positive samples from unpaid blood donors in Beijing is different from other regions. The two kinds of ELISA reagents used in this study showed no statistical difference.
