Two hepatitis C antibody assays were used to test diluted positive sera. Dilutions of 1 in 5, 1 in 10, and 1 in 20 all resulted in loss of reactivity, with the greatest losses occurring in samples with low and moderate reactivities. These results disqualify pooling as a strategy for seroprevalence studies and screening programs.
使用两种丙型肝炎抗体检测方法对稀释后的阳性血清进行检测。1:5、1:10和1:20的稀释度均导致反应性丧失,反应性低和中等的样本丧失最为明显。这些结果表明,混合检测不适用于血清流行率研究和筛查项目。
