[目的]分析造成孕产妇HIV初筛假阳性的原因和确认试验HIV抗体不确定的可能因素,预测HIV抗体不确定孕产妇抗体进展情况。[方法]对孕产妇HIV筛查阳性样本进行免疫印迹试验(WB)确认,对结果为HIV抗体不确定的孕产妇进行随访检测并对结果进行分析。[结果]随访到的7例孕产妇仅1例最终确认为阳性。[结论]妇女怀孕期间,体内各项指标的变化可能导致HIV抗体检测出现不确定结果,应结合其他检测方法,如病毒载量检测等以及流行病学调查辅助做出准确的诊断。 [Objective] To analyze the causes of false positive HIV screening of pregnant women and the possible factors that confirm the uncertainty of HIV antibody test, and predict the progress of HIV antibody uncertain maternal antibody. [Methods] Positive samples of HIV screening from pregnant women were confirmed by Western blotting (WB). Follow-up tests on pregnant women with HIV antibody uncertainty were performed and the results were analyzed. [Results] Only one case of 7 pregnant women who were followed up was finally confirmed as positive. [Conclusion] The change of various indexes in pregnant women may lead to the indefinite result of HIV antibody test during pregnancy, and should be combined with other test methods such as viral load test and epidemiological investigation to make accurate diagnosis.
