作者1992年5月31日至1993年5月31日对726名出入境人员及涉及婚姻人员的血清混合为242份,用明胶颗粒凝集(PA)试剂检测HIV—1抗体,结果未检出HIV—1抗体阳性血清,检出1份假阳性混合血清,假阳性率0.4%(1/242)。用常规法检测原血清,均未检出阳性性清,表明混合血清检测HIV—1抗体不会发生漏检。混合血清检测比常规方法减少66.25%成本,约减少50%的实验室操作时间。 Between May 31, 1992 and May 31, 1993, 242 serum samples from 726 immigrants and married persons were mixed, and HIV-1 antibodies were detected using gelatin particle agglutination (PA) reagent. As a result, no HIV was detected -1 antibody positive serum. One false positive mixed serum was detected, the false positive rate was 0.4% (1/242). Using the conventional method to detect the original serum, were not detected positive serum, indicating that mixed serum detection of HIV-1 antibodies will not occur missed. Hybrid serum detection reduces the cost by 66.25% compared to conventional methods, reducing laboratory operating time by approximately 50%.
