This study compared levels of human immunodeficiency virus type 1 RNA in plasma as measured by the Quantiplex branched-DNA and NucliSens nucleic acid sequence-based amplification assays. RNA was detectable in 118 of 184 samples (64.13%) by the Quantiplex assay and in 171 of 184 samples (92.94%) by the NucliSens assay. Regression analysis indicated that a linear relationship existed between the two sets of values (P < 0.0001), although the Quantiplex and NucliSens values were significantly different (P < 0.001), with the NucliSens values being approximately 0.323 log higher. Spearman correlation analysis indicated that the overall changes in patient viral load patterns were highly correlative between the two assays: r = 0.912, P < 0.0001. The lower limits of sensitivity were determined to be approximately 100 copies/ml and 1,200 to 1,400 copies/ml for the NucliSens and Quantiplex assays, respectively.
本研究比较了采用Quantiplex分支DNA法和NucliSens基于核酸序列扩增法检测血浆中1型人类免疫缺陷病毒RNA的水平。通过Quantiplex法在184份样本中的118份(64.13%)检测到了RNA,通过NucliSens法在184份样本中的171份(92.94%)检测到了RNA。回归分析表明,两组数值之间存在线性关系(P<0.0001),尽管Quantiplex法和NucliSens法的数值存在显著差异(P<0.001),NucliSens法的数值大约高0.323个对数。Spearman相关性分析表明,两种检测方法在患者病毒载量模式的总体变化上高度相关:r=0.912,P<0.0001。NucliSens法和Quantiplex法的检测灵敏度下限分别确定为约100拷贝/毫升和1200至1400拷贝/毫升。
