Preliminary Application Study
A nation-wide survey for HCV NATCoded panel for the survey
- Genotype 1b, 2a, 2b (200-300 IU/mL)- Negative plasma
Participants: - COBAS AMPLICOR : 92 HPs and Labs- AMPLICOR (MWP) : 32 HPs and Labs

ResultFalse negative result
- 1b : 2.4% (3/124)- 2a : 6.5% (8/124)- 2b : 2.4% (3/124)- Neg : 0.0% (0/124)
11 sites gave false negative results9 with COBAS, 2 with MWP
Improvement ==>> No false negative nor positive result in 11 sites in the follow-up survey
