(简称罗氏试剂)和雅培的HBV DNA诊断试剂.前者定量范围广(12IU~1.1×10~8/mL),敏感性高.2010年湖南圣湘生物科技有限公司成功研发了磁珠法高敏感HBVDNA实时荧光PCR定量试剂(简称磁珠法试剂).本研究拟比较国产高灵敏度HBVDNA实时荧光PCR定量试剂与罗氏试剂对CHB患者临床标本检测的敏感性和临床应用的优缺点.方法635份...
Conducting antiviral therapy is aim to decrease the HBV viral load and the replication ability of the virus, so HBV DNA detection is important during hepatitis B antiviral therapy because it can evaluate the possibility of antiviral resistance....
HBV DNA quantification and serological tests. Serum HBV viral load was assessed by using real-time fluorescent quantitative polymerase chain reaction (Real Time-PCR) on Roche Light Cycler 480II (Roche Diagnostics, Basel, Switzerland) with a lowest limit of detection of approximately 103 viral ...
Monitoring the serum hepatitis B viral DNA levels with sensitive realtime PCR assays is strongly rec- ommended for the management of patients with chronic HBV infection. This study compares the performance of two realtime HBV quantitative PCR assays with samples from chronic HBeAg(+) and HBeAg(...
Quantitative HBV DNA testing was undertaken at OUH NHS Foundation Trust clinical diagnostic microbiology laboratory using the Cobas TaqMan assay (Roche Diagnostics, Branchburg, NJ), with a lower limit of detection of 9 IU/ml. Serum HBV e-antigen (HBeAg) was measured using Centaur (09/2004–...
4 HBV viral load measures the amount of virus in a blood sample and is important when assessing viral replication or response to treatment. Although these methods have been effective, more recent assays improve the probability of diagnosis and quantification.5 Device Aptima: Designed by Hologic, ...
