Yes, a blood transfusion in the past could be responsible, especially if before 1992. The tattoo can be a problem if done among friends with a shared needle.

Await the PCR. If the viral load is detectable, he should have evaluation by someone knowledgeable about HCV infection. Not everyone develops disease. But, we also have effective treatments for HCV as well so he should be well regardless.
