摘要
目的收集HIV抗体免疫印迹法检测中出现的不确定结果，统计分析各种带型的临床意义，为检验人员提供判定结果的方法和建议。方法采集187份不确定实验结果和随访复检结果，以随访最终结果为金标准，统计分析各种带型出现的频度和阳性预测值，分析非特异性条带出现的频度和复检结果。结果条带gp160、p24的阳性预测值分别为32．1％和18．84％；两者同时出现时阳性预测值为100．00％，其他特异性条带的出现几乎不能提高阳性预测值，出现非特异性条带的样本最终均可确认为阴性。结论检验人员可以根据带型特征对不确定结果进行判定。
Objective To provide some methods on verifying indeterminate results in western blot confirmatory testing for HIV antibodies with statistic analysis. Melhods 187 indeterminate samples with final results in follow-up visit were gathered and analyzed. Results Positive predictive value （PPV） of gp160 and p24 band were 32.14% and 18.84%, gp160/p24（both） were 100.00%. Other specific bands couldn＇ t increase the PPV, and non-specific bands predictive negative result. Conclusions Technicians can verify the indeterminate results initially by discriminating the different bands.
