Hi Rauf, If you can pinpoint a risk factor that you have, you may be able to make an educated guess. For example, if you had a blood transfusion before 1992, that is likely your answer. Or if you ever used IV drugs and shared works, that would be a way to answer your question, as well. The bottom line is that it doesn't matter how or when you got hepatitis C, You deserve treatment. If you do not have insurance, you may want to consider calling Help4Hep at 877-435-7443. They may be able to help you access care. The call and help are free. Good luck, Rauf.
