Hi there, you can stop worrying and live your life to the full. Is it hepatitis C
that you are worried about or is it something else? Usually seroconversion
takes place by 6-8 weeks after exposure and you would test positive for the infection after that so as the episode occured an year ago and you have tested negetive on two occasions it is unlikely for you to have got infected during that episode. In the future you would like to be a little more careful and spare yourself this mental trauma. For now you can be rest assured that you are fine if you have not tested positive on two tests even after an year of exposure. For the future take care!
