HAV antibody indicates prior or acute infection with, or immunization to, Hepatitis A virus.
Hepatitis C Virus (HCV) is the major cause of hepatitis. Approximately 1% of blood donors are seropositive for anti-HCV. The clinical symptoms of a HCV infection are variable. Exposure to HCV results in a chronic infection in 50 to 80% of cases. The "window" between infection and seroreactivity is highly variable, up to 12 months.
