在HCV抗体检测结果呈阳性或模棱两可、不确定的情况下,应进行丙型肝炎病毒核酸(HCV RNA)检测,以评估是否存在活动性病毒血症。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...
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 ...
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...

HCV genotypes in Swedish blood donors as correlated to epidemiology, liver disease and hepatitis C virus antibody profile. Sixty-two anti-HCV and HCV-RNA positive Swedish blood donors (44 men, 18 women; median age 34 years) were studied. HCV genotypes were correlated to parente... S Shev,...
Moreover HCVAg has been demonstrated to considerably reduce the window period in 97% of HCV-RNA positive/anti-HCV antibody negative specimens demonstrating that it represents a reliable marker of viral replication even in HCV pre-seroconversion phase [13, 19, 20]. To date, little data are ...
