Should i get tested for hcv if i a barber used a razor blade on me (i didn't see any cuts after that)?

No: Screening for chronic hcv infection is recommended for patients with certain risk factors only. For example, patients who have used injection drugs, those who received blood products before july 1992, hiv-positive individuals, and those with evidence of liver disease are some groups who should be tested. The screening recommendations for europeans are similar to those for americans.
