A quantitative reverse transcriptase PCR assay with automated detection by nonradioactive hybridization was developed for the determination of human immunodeficiency virus (HIV) type 1 RNA levels. This assay is based on the use of an external standard curve with an internal standard. The accuracy of quantification was verified by comparison with reference commercial tests, the Chiron branched-DNA and Roche AMPLICOR HIV MONITOR assays. This assay was able to quantify viremia in patients with CD4 cell numbers below and above 500/mm3 and to quantify some HIV strains which could not be titrated by the MONITOR assay.
开发了一种通过非放射性杂交进行自动检测的定量逆转录酶聚合酶链反应检测方法,用于测定1型人类免疫缺陷病毒(HIV)RNA水平。该检测方法基于使用带有内标的外标曲线。通过与参考商业检测方法(Chiron分支DNA检测法和罗氏AMPLICOR HIV MONITOR检测法)进行比较,验证了定量的准确性。该检测方法能够对CD4细胞数低于和高于500/mm3的患者的病毒血症进行定量,并对一些无法通过MONITOR检测法进行滴定的HIV毒株进行定量。
