Diagnosis

A positive chronic hepatitis B diagnosis requires follow-up, from clinical tests to patient education, including:1,2

Post-diagnosis follow-up and testing

Following a positive test result for chronic infection, patients will require a thorough history and physical examination followed by evaluation tests.1,2

  • 1. History and physical examination to assess:
  • Risk factors for viral hepatitis
  • Family history of HCC
  • Route of transmission
  • History of alcohol use
  • Presence of comorbid
    diseases
  • Risk factors for HIV coinfection
  • Duration of infection
  • 2. Evaluation tests may include:
  • Serial testing for HBV DNA and ALT
  • HBeAg and anti-HBe
  • LFTs, including CBC, PLT and PT
  • Tests for antibodies to HAV, HCV, HDV, and HIV
  • HCC screening
  • Transient elastography or liver biopsy*
  • Urinalysis
  • HBV genotype

ALT=alanine transaminase; CBC=complete blood count; HAV=hepatitis A virus; HBV DNA=hepatitis B virus deoxyribonucleic acid; HCC=hepatocellular carcinoma; HCV=hepatitis C virus; HDV=hepatitis D virus; LFT=liver function tests; PLT=platelet test; PT=prothrombin time.
*Liver biopsy is optional for patients indicated for treatment, but may be helpful in those with normal ALT and >35-40 years of age.

Transmission

CHB patients may not be aware of how they contracted the virus.3

In the United States, the most common routes of transmission are through perinatal and sexual contact but it may be transmitted through any type of exposure to body fluids, such as blood and semen, of people with either an acute or chronic hepatitis B infection.4

  • Perinatal transmission is the major route by which hepatitis B infection is perpetuated in endemic populations5,6
  • Children born to mothers infected with chronic hepatitis B, who are not perinatally infected, remain at risk of horizontal transmission so vaccination should be considered.5

There are many myths about how hepatitis B is transmitted so appropriate patient education about the virus and common routes of transmission is important.7
