I took a HCV RNA test. My doctor said that the virus is not replicating. Does this mean I'm cured or it's hibernating?

Cured. If you have a positive antibody but a negative hcv RNA while on no anti-hcv therapy, then your body either cleared the infection on its own, or you were medically cured. Either way, it's good news, .
SVR. Sound like you have a sustained viral response. Basically, it means you have cleared the virus.
