We compared the positive- and the screening-rates in HCV-antibody test between public and occupational health examinations in 159,707 and 30,850 individuals, respectively. In the public and occupational examinations, the positive rates were 1.90% and 1.61%, and the relative rates in the under 60-year of age to all positives were 31.8% and 63.7%, while the screening rates were 99.9% and 27.2%, respectively. The positive rate was higher in older and in male in the public examination, while there was no marked difference between genders and between age-ranges in the occupational examination. Establishment of HCV-testing system in all of health examination is desirable for early detection and treatment of HCV infection.
