Any person who has ever had HCV will produce a "reactive" result in an antibody test, including people with active HCV infections, people who cleared it on their own without treatment, and those who have been cured through treatment. If a client has a reactive HCV Antibody test they are then referred to confirmatory HCV RNA testing that will show whether they have an active infection that requires treatment or a former infection that doesn't require treatment. Once people get treated they are unable to spread the virus which helps us to turn the curve on the number of new HCV infections (incidence) as well the total number of HCV cases in San Francisco (prevalence). Increasing the number of antibody tests is one of End Hep C SF's primary goals because it means that we are testing more people who are at risk for HCV and linking more people to RNA testing and HCV treatment.
