i would think it was... especially after 10 yrs.. get tested a 2nd time in if any doubt down the road
Do you mean continuous exposure for a period of ten years or one exposure ten years ago?
If you have waited between 3 and 6 months since your last exposure, a neg antibody test is reliable.
I only been exposed once by a poke of a contaminated tattoo gun. That was when I was in 7th grade. I am now 25 and last got tested when I was around 21.
Worry about something remotely possible, like getting hit by a bus or the sun rising in the west.
You don't have hep c.
