Hepatitis C RNA test, to first extract RNA, the RNA through the instrument, reverse transcription test, the RNA into cDNA, and then into double-stranded DNA, that is, reverse transcription fluorescence quantitative PCR instrumentation method, you can detect the hepatitis C virus RNA. Hepatitis C virus RNA test and hepatitis B virus DNA test is different, the hepatitis C virus is the RNA test, the RNA can not be detected at a time on the use of the instrument. Hepatitis C virus RNA test is different from hepatitis B virus DNA test. In addition to the common PCR method now, there are reverse transcription digital fluorescence quantitative PCR method is also better, and do the test more efficient, more accurate results.
