Actually, the blood will always test positive for antibodies to the virus if one has been exposed. But as copyman says, treatment with medications can clear the live virus from the blood. So the antibody test will always be positive but the PCR (test for the live virus) will be negative after successful treatment.
Welcome to the forum, it's a great place to ask your questions.
The ONLY way to make a person negative of HCV is to treat with drugs. There are news drugs on the market plus others in research that make treatment around 70-80% successful. Good luck
Hepatitis is a dynamic, changing disease. It is possible for people to clear with or without treatment. If you have cleared, I'm very happy for you. Sometimes people go their whole lives without realizing they even have Hep c. I hope you have cleared. Good luck and God bless.
