Ags/Abs for testing? HAV
IgM anti-HAV = acute
Total anti-HAV = immunity
Ags/Abs for testing? HBV
HBsAg, HBeAg, IgM anti-HBc = acute
IgM + IgG anti-HBc = chronic
IgM loss, IgG anti-HBc and anti-HBs = recovery
Anti-HBs = immunity
Ags/Abs for testing? HCV
Anti-HCV or HCV RNA testing
Ags/Abs for testing? HDV
IgM anti-HDV = acute
IgG anti-HDV = convalescence
IgM + IgG anti-HDV persistence = chronic infection
Ags/Abs for testing? HEV
