2015年淮安市HIV抗体初筛阳性标本复检与确证结果分析
[Abstract]:Objective to investigate the results of reexamination and confirmation of HIV (HIV) antibody positive specimens in Huaian City in 2015, and to provide evidence for AIDS prevention and treatment. Methods (ELISA) and colloidal selenium test were used to recheck the positive samples of the first screen, and any of them was positive, even if it was confirmed by Western blotting test (WB). Results among the 211 positive specimens, 200 were to be confirmed (200 / 21194.8%), 10 were positive in the past, and 190 were detected by WB confirmatory test. Among them, 134 were positive for HIV-1 antibody, the positive rate was 70.5% and the negative rate was 38. The negative rate of HIV antibody was 20.0%, accounting for 9.5%. In the confirmed positive specimens, the occurrence rates of gp160 and gp120 were 100.0%, 48.5% and 38.1%, respectively. A single band of p24 was found in the uncertain specimen, accounting for a maximum of 44. 4%. Conclusion the false positivity of screening test is inevitable, it is necessary to confirm HIV infection by WB test, and to strengthen follow-up test for uncertain samples.
