Methods: The paired urine and serum specimens from 273 drug users detained at a detoxification unit were collected, and the HIV-1 antibodies in the specimens of them were screened by urine and serum ELISA kits, respectively. Results: Of 273 serum specimens, 94 ones showed positive reaction and among 94 counterpart urine specimens, 93 ones also appeared positive reaction. Taking the results together,the consistent rate of HIV-1 antibody screened by urine and serum ELISA kits was 99.6%. Conclusion: The urine ELISA kit, which screened HIV-1 antibody of urine showing almost the same results tested by serum ELISA kit, is reliable. It is proposed that urine ELISA be introduced in many fields.展开更多
目的 探讨酶联免疫法和金标法对HIV抗体的检测结果,明确针对艾滋病更为有效的临床筛查手段。方法选取264例疑似艾滋病患者,采集入组患者静脉血并进行酶联免疫法与金标法检测HIV抗体。以临床诊断结果为准,比较酶联免疫法和金标法与临床...目的 探讨酶联免疫法和金标法对HIV抗体的检测结果,明确针对艾滋病更为有效的临床筛查手段。方法选取264例疑似艾滋病患者,采集入组患者静脉血并进行酶联免疫法与金标法检测HIV抗体。以临床诊断结果为准,比较酶联免疫法和金标法与临床检查结果的一致性;比较酶联免疫法和金标法对艾滋病的诊断效能。结果 264例疑似艾滋病患者中,经临床筛查试验和确证试验确诊225例。κ检验分析结果显示,酶联免疫法检查结果与临床诊断结果具有高度一致性(κ=0.897, P <0.05);金标法检查结果与临床诊断结果具有高度一致性(κ=0.902, P <0.05)。酶联免疫法与金标法诊断艾滋病的灵敏度、特异性与准确率比较,差异均无统计学意义(P>0.05)。结论 酶联免疫法和金标法对HIV抗体均具有较好的检出效果,可为艾滋病临床诊断提供较为准确的数据参考,临床检测中可根据患者自身情况选择相应的检测方法,必要时还可进行联合检测。展开更多

文摘目的评价Roche电化学发光法联合检测HIV抗原抗体试剂的检测性能。方法收集包括健康献血员、人类免疫缺陷病毒(HIV)感染者、丙型肝炎病毒(HCV)抗体阳性和高危人群在内的血清样本1 327例。购买美国BBI公司的7套HIV血清转换盘共计51份血清样本。采用Roche cobas e411(架式系统)电化学全自动免疫分析仪和相应的检测试剂、校准品和质控品以及检测参数进行测定。以Roche Elecsys HIV Combi试剂盒为评估试剂,以生物梅里埃Vironostika Uni-FormⅡplus O HIV抗体试剂盒为参比试剂。定性检测血清HIV p24抗原和HIV1/2抗体并评价检测方法分析性能、结果一致性和血清转化灵敏度。结果 Roche Elecsys HIV Combi试剂盒批内和天间不精密度良好,符合临床使用要求。血清样本检测结果和参比试剂检测结果一致性完全符合。评估试剂的血清转化灵敏度比参比试剂平均提前了5.1 d。结论 Roche Elecsys HIV Combi试剂盒具有良好的精密度和血清转换灵敏度,有利于筛查HIV早期感染,能为临床HIV早期诊断、随访监测提供有效的实验室诊断依据。
