Went in for my 4 week dr appt yesterday. At two weeks, the lab acidentally did a VL draw. At two weeks, went from 4.1M VL to 53!!!! Dr is confident my 4 week results will come back as UND! Wont know for sure for a few day but ......After treating and not being successful before, this is EXCELLENT news! happy dance, happy dance..oh cha cha! I feel the earth move under my feet... OK, enough of my virtual serenade! Anyway, so if one is UND at week 4 anyone know the probability of achieving SVR?
