Hi, !
I don't blame you for being concerned about possible HCV transmission due to a clipper nick.
Please keep in mind that I am not a doctor and can not provide medical advice. That said, the risk of catching HCV from an injury like this is low, but not zero. If your barber is properly sanitizing his tools (including razor and clipper heads) in a disinfectant solution (such as Barbicide), then your risk should be negligible. Since you mentioned that the clipper may not have been sanitized, well, that does up the risk factor a bit.
So, for your peace of mind, if you would prefer to be tested, you have the right to do so. Getting tested is easy and most insurance plans will cover the testing. If you need help finding resources, please let me know and I would be happy to help!
Again, the decision is yours and I am sorry you are in this position right now! Also, if it's appropriate, I would either find a new barber or have a talk about sanitizing tools with your barber. He is at risk too if he doesn't disinfect his tools properly.
