现行艾滋病血清学诊断分初筛试验和确证试验。初筛试验用于检测HIV特异性抗体总量,需用2种方法或1种方法2次检测,最常用颗粒凝集试验(PA)或ELISA,但不可出阳性结果报告,其试验阳性或可疑标本应及时作确证试验。确证试验用于检测HIV组分抗原的特异性抗体,主要用蛋白印迹试验(WB)。确证试验HIV特异性抗体阳性并结合临床机会感染及症状,可诊断现症艾滋病;HIV特异性抗体阳性而无临床症状者系HIV感染潜伏期或HIV携带者;HIV特异性抗体阴性或可疑者6个月内经复查仍不为阳性者,可排除HIV感染的可能性。
The current AIDS serodiagnosis sub-screening test and confirmatory test. The primary screening test is used to detect the total amount of HIV-specific antibodies. Two tests or one test should be performed twice. The most commonly used particle agglutination test (PA) or ELISA, but no positive test results, positive or suspicious test samples Should be confirmed in time for the test. Confirmation Test Specific antibodies used to detect HIV component antigens, primarily Western blotting (WB). Confirmatory test HIV-specific antibody positive and combined with clinical opportunistic infections and symptoms can be diagnosed with AIDS; HIV-specific antibodies without clinical symptoms of HIV infection incubation period or HIV carriers; HIV-specific antibody negative or suspicious 6 The month after the review is still not positive, you can rule out the possibility of HIV infection.
