Hi there. To be considered an RVR responder you would have had to have been Undetected at your 4Wk.Viral load test.
You have still had a good response (>2.5logs) and the next important VL test will be at week 12 as you can see in the info. below
I have linked the entire article if you are intested in going over it.
Good luck and welcome to the group..

In a meta-analysis evaluating customized treatment of patients with HCV-2 and -3 in four studies, including 957 patients for whom separate data are available for both genotypes, we showed that SVR rates in HCV-3 patients with RVR were similar to those of HCV-2 patients [20]. The difference between the two genotypes is the probability of SVR in patients without RVR. In the absence of RVR [20], EASL guidelines advise 24 or 48 weeks of treatment depending on whether the patient is HCV RNA-negative or if there is a greater than 2 log10 decline in HCV RNA at week 12 respectively. However, the recommended schedule for HCV-2 and HCV-3 patients is the same [
