Systematic sequence analysis of human immunodeficiency virus type 1 (HIV-1) variants with RNA levels underestimated by the Cobas TaqMan HIV-1 assay demonstrated that mutations at a single position of the downstream primer can lead to the underestimation of HIV-1 RNA levels by more than 2 log and to false-negative results in minipool screening of blood donors. Mutations at this position are found in about 2% of all HIV-1 M gag sequences.
对人类免疫缺陷病毒1型(HIV-1)变异体进行系统序列分析,这些变异体的RNA水平被Cobas TaqMan HIV-1检测法低估,结果表明下游引物单个位置的突变可导致HIV-1 RNA水平被低估超过2个对数,并在献血者混合样本筛查中产生假阴性结果。在所有HIV-1 M gag序列中约2%发现了该位置的突变。
