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呈阳性、HCV ...
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 ...
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...

Prevalence of Hepatitis C Virus RNA in Organ Donors Positive for Hepatitis C Antibody and in the Recipients of Their Organs Among 13 recipients who were HCV RNA-negative before receiving organs from the nine HCV RNA-positive donors, HCV infection was detected in all 13 after transplantation, and...
(range, 12.3 to 29.6 years). Among these HCV-infected individuals, 30 individuals were anti-HCV IgG positive and HCV RNA positive (Chronic), the remaining 8 individuals were anti-HCV IgG positive and HCV RNA negative (Recovery). The average of HCV virus titer was 4.19 × 105copies/...
Persistence of HCV-RNA in a Blood Donor with Negative Antibody Assays We studied the sera from 21 healthy blood donors with positive HCV serology for a period of 2 years to evaluate HCV antibody dynamics and possible viremia... M Rapicetta,S Dettori,LA Kondili,... - 《Vox Sanguinis》 被...
We evaluated the prevalence of hepatitis C virus (HCV) RNA and antibody (anti-HCVcore) to the putative HCV core protein in Japanese patients with chronic liver disease. Sera were screened by solid-phase enzyme immunoassay with a recombinant HCV core protein and by the reverse transcription-polyme...
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-...
