I have hepatitis B, HBsAg positive. I have been taking the antiretroviral drug tefostad for almost 4 years. Recently, I went to have ALT, AST normal, liver ultrasound normal, HBeAg negative, Anti HBe negative, HBV automated system load measurement, but no HBV-DNA was detected in the sample. Doctor tell me, what does hepatitis B test mean? When should I stop taking antiretroviral drugs and if I stop antiretroviral drugs will my illness get worse
