HCV RNA PCR是一种使用称为聚合酶链式反应(PCR)的技术检测血液中丙型肝炎病毒的遗传物质(也称为RNA)的测试。 HCV RNA PCR的名字来源于测试内容的和所使用的过程的缩写: ➤ HCV——丙型肝炎病毒 ➤ RNA——核糖核酸 ➤ PCR——聚合酶链式反应 医生可能会推荐不同的方法来减少体内的病毒数量,也就是所谓的...
By quantifying levels of HCV RNA in these patients, the test can be used early in the course of treatment to predict the likelihood of a sustained virologic response being achieved and can also be used to assess virologic response during treatment as part of response-guided therapy. The test ...
The COBAS® AmpliPrep/COBAS® Taqman® HCV Quantitative Test, version 2.0, is an in vitro, fully automated, real-time, nucleic acid amplification test indicated for quantifying hepatitis C virus (HCV) RNA levels in the plasma/serum of patients infected with HCV of genotypes 1–6 who are...
The results suggest that the first qualitative HCV-RNA PCR test should be delayed until after the first month of life given the low sensitivity in the first few weeks. Although a negative test result after this time indicates probable absence of infection, this should be confirmed with a ...

HCV RNA test should be used to confirm HCV viremia in patients with a positive anti-HCV by the following criteria: if the anti-HCV S/CO ratio is <10.9, a qualitative HCV RNA test can be used, and if the anti-HCV S/CO ratio is ≥10.9 a quantitative HCV RNA test can be performed....
、HCV-RNA、RIBA 等,对于 HCV 的检测,美国 CDC 发布了 HCV 实验室检测导则,其宗旨是使实 验室报告的结果更可信,更有利用价值。我国目前情 况与该导则要求相去甚远 [6] 。 统计室间质评结果,上海科华和厦门新创属于 图1 两种试剂盒不精密度曲线 Fig.1 The coefficien of variation curve of two reagent...
近年来实验室诊断丙型肝炎病毒(HCV)PCR法已向标准化和"即可用"的方向发展.本试验用来自5个检测中心的2000多份标本对首台自动化扩增和检测HCV RNA的仪器COBAS在日常实验室工作中的性能进行了评估.结果表明,自动的COBAS法与AMPLICOR手工法同样准确,符合率达99.8%.PCR法与血清学方法的结果并不完全一致,因为抗HCV抗体...
New Automated Hepatitis C Virus (HCV) Core Antigen Assay as an Alternative to Real-Time PCR for HCV RNA Quantification An automated hepatitis C virus (HCV) antigen (Ag) assay was evaluated with clinical samples. Determination of HCV Ag and RNA levels in 282 subjects using A... Y Park,JH...
Qualitative PCR was carried out in quadruplicate using two separate 5′UTR primer sets (8 results/specimen). A specimen was positive if ≥ 1 gels was positive compared to controls. At weeks 12 and 24, 9/9 (100%) sustained response patients were negative by ultracentrifugation. In the 23 ...
