Chronic viral hepatitis C is clinically investigated by blood sampling: first, to see if there are antibodies to viral hepatitis C; second, to check the HCV-RNA virus, which is the type C virus. Now it is very convenient, most large hospitals have this test means, a check is very clear. I hope that all people who have not had the test must remember to check for hepatitis C antibodies, or when there are hepatitis C antibodies, to check for the virus, that is, the HCV-RNA virus, for screening. If the test determines, for example, that there are antibodies, there is HCV-RNA virus, and the treatment is now more effective. What is now available in China is called Propecia Tone, which can treat almost all genotypes of the hepatitis C virus.
