Answer

History and physical examination: Thoroughly evaluate for the following:

  • Alcohol, metabolic, and other risk factors for HBV infection
  • Patient's HBV vaccination status
  • Family history of HBV infection and hepatocellular carcinoma
  • The presence of symptoms/signs of cirrhosis

Routine laboratory studies

  • CBC, platelet count; INR
  • Levels of AST, ALT, total bilirubin, ALP, and albumin

Serologic/virologic studies

  • Hepatitis B e antigen (HBeAg)/anti-HBe
  • HBV DNA level
  • Anti-hepatitis A virus (anti-HAV) (to determine need for vaccination)

Imaging/staging studies 

  • Abdominal ultrasonography
  • Vibration-controlled transient elastography (eg, FibroScan) or a serum fibrosis marker panel (APRI [AST-to-platelet ratio index], FIB-4 [platelet count, ALT, AST, age], or FibroTest [gamma-2 macroglobulin, gamma-2 globulin, gamma globulin, apolipoprotein A1, gamma-GGT, total bilirubin])
