Surveillance of screening for hepatitis C through the laboratory network RENA-VHC, France, 2000-2001.

Over the period 2000-2001, 189 private or hospital laboratories scattered throughout France participated to the laboratory network RENA-VHC. A total of 759 591 serologies (screening tests and validation of screening tests) were performed, revealing an increase of 10% between 2000 and 2001. The rate of the amount of tests to validate screening found positive over the overall amount of tests performed was 1.2% in 2000 and 1.0% in 2001. This suggests that screening covered more people with little risk of acquiring HCV infection. The per-sons confirmed HCV positive were predominantly men (sex ratio 1.5) of which 31% were30 to 39 years of age.
