Q

Consequence of chronic? HBV

A

25% of chronic carriers get cirrhosis/CA

Q

Q

Ags/Abs for testing? HAV

A

IgM anti-HAV = acute
Total anti-HAV = immunity

Q

Ags/Abs for testing? HBV

A

HBsAg, HBeAg, IgM anti-HBc = acute

IgM + IgG anti-HBc = chronic

IgM loss, IgG anti-HBc and anti-HBs = recovery

Anti-HBs = immunity

Q

Ags/Abs for testing? HCV

A

Anti-HCV or HCV RNA testing

Q

Ags/Abs for testing? HDV

A

IgM anti-HDV = acute

IgG anti-HDV = convalescence

IgM + IgG anti-HDV persistence = chronic infection

Q

Ags/Abs for testing? HEV

A
