How is the response to treatment measured?
Several medical terms and abbreviations are used to describe responses to HCV treatment (see Table 3).
The most important of these is SVR-12 because this defines if HCV is cured.

SVR-12 means having an undetectable HCV viral load 12 weeks after the end of treatment. This is considered a cure. |
