如果HCV RNA检测呈阳性,则可确认存在活动性HCV感染,并有必要进一步检测HCV的基因型,并开始指导治疗。 对于抗-HCV呈阳性、HCV RNA呈阴性的无症状患者,进一步的筛查思路如下: 首先,应获得详细的病史,以评估与丙肝感染风险增加相关的危险因素、行为...
Kidney transplantation from a donor who is HCV antibody positive and HCV-RNA negative.plasma tumour necrosis factorrenal transplantationhaemodialysisPlasma tumour necrosis factor levels were measured serially in 16 patients following renal transplantation, and in 10 patients on haemodialysis and in 12 ...
False-positive serologyBackground: Hepatitis C virus (HCV) status cannot be reliably predicted in anti-HCV positive/HCV-RNA negative individuals who may either have recovered spontaneously or have a false-positive test due to antibody cross-reaction. Investigating T lymphocyte responses in individuals ...
Should they be dropped from the donor pool because their donations test unspecifically positive in the HCV-EIA screen, even on a number of occasions over a long period of time, or should they remain in the donor pool as there is a good chance they will convert to negative test results?
In this stuyd, 45 plasma samples from anti-HCV antibody-negative/HCV RNA-positive (window period) donors from Poland identified during nucleic acid testing (NAT) and 32 follow-up anti-HCV antibody-positive samples were tested retrospectively for HCV core antigen by Ortho Clinical Diagnostics first...
In two HCV-Ab positive but HCV-RNA negative patients, basal 2′5′-OAS was similar to uninfected patients. In HCV-RNA positive patients, indomethacin alone was able to significantly increase the 2′5′-OAS production in a similar fashion to IFN-α alone, while a synergistic effect on 2′...
(RNA)荧光定量及丙型肝核心抗原(HCV-Ag) 三种试剂盒分别检测血清中的HCV-Ab、HCV-RNA、HCV-Ag三种标志物.结果 根据丙型肝炎病毒在体内存在的时间,通过90例疑似丙型肝炎患者血清检测,HCV-Ab 87人阳性,HCV-RNA 67人阳性,HCV-Ag 55人阳性.结论 HCV-Ab、HCV-RNA、HCV-Ag联合检测有助于临床诊断、用药及疗效...
In all infection experiments, primary B cells and Raji cells not exposed to HCV (uninfected) and incubated with normal human plasma under the same culture conditions as the cells exposed to HCV were included as negative controls. Detection of HCV RNA-positive and -negative strands HCV RNA-...
Objective:To explore the diagnostic value of HCV RNA,the core antigen of HCV,HCV antibody in serum of patients with hepatitis C.Methods:Serum from 62 HCV RNA positive and 64 HCV RNA negative outpatients and inpatients were collected to detect the HCV antibody,HCV-RNA and HCV-cAg by time-res...
February 2015,received during the period of 120 patients with HCV-RNA positive for hepatitis c,using different methods respectively to check patients alanine aminotransferase( ALT) levels,HCV antigen( HCV-the c Ag),HCV antibody( HCV-Ab) and HCV-RNA,and to all the data for statistical analysis...
