I can give you 150% assurance that Valtrex has absolutely no impact on Hepatitis B or C testing.
May I ask why you have not been vaccinated for Hepatitis B if you are this concerned about it?
How old are you? Perhaps you were already vaccinated as a child? Do you recall the exact results of your hepatitis B antibody test? Or was it an antigen test?
You can definitely trust the results of the hepatitis antibody tests.
