My HCV RNA test is negative, so then how often should I get rechecked?

May be no need. This is apparently an RNA PCR (polymerase chain reaction) test that determines virus particles, or viral load in the body. This can be negative, but if an immunoblot test was positive, it would mean that you had an infection with hepatitis c and it was cleared. If the immunoblot was negative, then you never had an infection, and if you had an immunoassay and it was positive, then it was wrong.
