I got dried blood on my hands after pumping gas but used hand sanitizer w/o noticing and may have spread to my cuts, should I be worried about hep c?

Wash cut immediatly. Wash cut immediately and treat with antibiotic cream like otc neosporin, hep c is not common with local contact.
HIGHLY UNLIKELY. It is VERY unlikely to contract Hep C from dried blood. But if you are concerned, to ease your mind, wait 3 months and have your doctor test you for it.
