Bigronny, do you know if your friend has been tested for hep C, and what the results were if he was tested? I don't think anyone here can tell you how much risk you have from that incident. Obviously, there is some. I suggest you go to your primary care doctor and request a hep C test. If it comes back positive, it could mean that you have been exposed to the virus and your immune system knocked it out (acute hep C), or that you still have the virus and it is attacking your liver (chronic active hep C.) Even if you were in contact with hep C and overcame it, it will still show positive for hep C. The only way to differentiate is through a liver biopsy. If it is not active, you don't have to do anything. If it is active, you will need treatment. So the first step is a specific test for hep C. You might want to get tested for hep B at the same time.
