It doesn't matter how anyone gets Hep c the only thing that matters is finding out and getting treated.
It only takes once. I only tried it 3 times back when I was 19 years old 39 years ago. That was all it took
I had never used a needle before, it was one drunken mistake that I deeply regret. Thanks for your answer.
Your test should be good but to make absolutely sure you can retest at 6 months post this incident. The 6 month post test is definitive.
Or you can have a test for the virus itself the HCV RNA by PCR test to check for the hep c virus. That test is more expensive but if it is negative you do not have hep c.
If your friend has only had the antibody test she should have the HCV RNA test as well to confirm if she is currently infected.
Good luck to you both.
If you are using IV drugs please use safely. If possible always use a fresh needle do not share works ever.
