abstract：:The detection of hepatitis C virus (HCV) RNA by nested polymerase chain reaction (PCR) is believed to be the most reliable method to diagnose HCV infections. A pitfall of nested PCR is that it is prone to contamination. Single step reverse transcription-PCR (RT-PCR) was performed, prospectively, on 80 sera from 59 pat...
