I tested negative at 4 months but was worried that the Valtrex course I took at the start somehow messed up the tests. Grace assured me no. I inquired about taking the Western Blot at U of Washington and they gave me some assurances about my results and interestingly stated that in their research, Valtrex may delay seroconversion by week or 2 max. certainly nothing past 4 months. I thought this was interesting and worth sharing. Hope everyone is well.
