目的:回顾分析往年HIV抗体筛查试剂的检测性能,给今后的试剂选择提供帮助与参考。方法:从台州市中心血站血液信息管理与监控系统中采集2004年-2010年抗-HIV检测结果数据,利用Excel进行汇总统计,用χ2检验进行试剂性能比较。结果:第3代梅里埃、第4代梅里埃、金豪3种试剂的特异度分别为99.91%、99.91%、99.93%,功效率分别为99.91%、99.91%、99.93%,阳性预期值分别为1.67%、10.92%、14.71%;金豪的阳性预期值与第4代梅里埃无差别(χ2=1.28,P>0.05)。结论:目前HIV抗体筛查试剂的检测性能能满足预期要求,而进口试剂并不一定优于国产试剂。
Objective: To retrospectively analyze the detection performance of HIV antibody screening reagents in the past years and provide help and references for future reagent selection. Methods: From 2004 to 2010, the anti-HIV test data were collected from the blood information management and monitoring system of Taizhou center blood station. The data of anti-HIV test were collected by Excel and the performance of reagents was compared by χ2 test. Results: The specificity of the 3rd generation Merillian, the 4th generation Merier and Jinhao reagents were 99.91%, 99.91% and 99.93%, respectively, and the power efficiencies were 99.91%, 99.91% and 99.93%, respectively. The positive predictive values were 1.67%, 10.92% and 14.71% respectively. The positive predictive value of Jinhao was no different from that of the fourth generation Merier (χ2 = 1.28, P> 0.05). Conclusion: At present, the detection performance of HIV antibody screening reagents can meet the expected requirements, while imported reagents are not necessarily superior to domestic reagents.
