摘要
目的研制HIV-1/2抗体和P24抗原联合检测酶免疫试剂盒并评价其实用性。方法联合使用基因工程HIV1/2型抗原和抗HIVP24单克隆抗体包被酶联反应板,以辣根过氧化物酶标记的HIV1/2型抗原和生物素化的兔抗HIVP24抗体作为标记物,研制了联合检测HIV1/2抗体和P24抗原的ELISA诊断试剂,并对其特异性、敏感性、稳定性等进行评价和临床考评。结果检测P24抗原质控品的灵敏度可达0.2ng/ml;与雅培公司试剂比较检测78份AIDS患者血清和85份正常人血清、对照检测中国药品生物制品检定所研制的HIV参比血清,特异度和灵敏度均为100%。临床考核检测12051份各种血清,灵敏度为100%(543/543),特异度为99.48%(11448/11508)。试剂在37℃放置6d后,试验结果无明显差异。结论本试剂盒具备特异度强、敏感度高、稳定性好、操作简便等优点,可以一步检出HIV特异性抗体和HIVP24抗原,缩短了HIV感染的检测窗口期,适用于HIV感染的实验室诊断和流行病学调查。
Objective To establish and evaluate an Enzyme Immunoassay diagnostic kit combined with anti-HIV1/2 antibody and P24 antigen for shortening the examination window period of HIV infection in HIV laboratory diagnosis. Methods The enzyme-linked reaction plates was coated by anti-HIV P24 monoclonal antibody and HIV 1/2 antigen. Labeling HIV1/2 antigen and anti-HIV P24 polyclonal antibody with horseradish peroxidase, setup an integrated EUSA kit for detcting anti-HIV-1/2 antibody and HIV P24 antigen, and evaluate the specificity and sensitivity of this kit. Results The sensitivity of testing P24 antigen was up to 0.2 ng/ml. 78 serum samples of patients with AIDS, 85 serum samples of healthy people were compared with Abbott EIA kit, the coincidence was 100% . 12 051 sera from normal persaons and patients were examined, the sensitivity of 100% and specificity of 99.62%, respectively. Condasion The anti-HlV1/2 antibody and HIV P24 antigen can be measured at the same time using this EIA kit, while the examination window period of HIV infection is shortened. Thus, the method is suitable for laboratory diagnosis and epidemiological investigation.
