Importance of RT-PCR for detection of hepatitis C virus among different patient groups. Indian Journal of Medical Research. 1998 Sep; 108(): 85-7http://imsear.searo.who.int/handle/123456789/25389A pilot study was undertaken to evaluate a sensitive single step reverse transcription polymerase chain reaction (RT-PCR) to detect hepatitis C virus (HCV) RNA in plasma samples as an adjunct to antibody detection. In this study, digoxiginin labelling of the amplicon was carried out during the PCR and the product was detected by an ELISA format (DIG-ELISA) as well as ethidium bromide stained gel detection. DIG-ELISA detection of PCR product compared favourably with gel detection. We tested 42 individuals with either parenteral risk factors or chronic liver disease and found the RT-PCR enhanced the detection rate by 19 per cent. Considering either plasma RNA or antibody positivity, HCV infection was detected in 64.3 per cent of patients.engChronic DiseaseEnzyme-Linked Immunosorbent Assay --methodsHepacivirus --geneticsHepatitis C --bloodHepatitis C Antibodies --bloodHumansLiver Diseases --bloodPilot ProjectsPolymerase Chain Reaction --methodsSensitivity and SpecificityJournal Article
