II. Indications

  1. Universal screening for U.S. Adults is recommended as of 2023
    1. Triple Screen (HBsAg, HBsAb, HBcAb) at least once in all adults regardless of risk factors
    2. Conners (2023) MMWR Recomm Rep 72(1):1-25 +PMID: 36893044 [PubMed]
  2. Risk Factor Based Screening
    1. Pregnant women at first Prenatal Visit
    2. HIV Positive patients
    3. IV Drug Abuse
    4. Men who have Sex with Men
    5. Household contacts or sexual partners of infected persons
    6. People born in countries with high Prevalence of Hepatitis B Infection (2% or greater Prevalence per CDC)
    7. U.S. born children (but not HepB vaccinated) to parents from countries with Prevalence of Hepatitis B Infection (>8%)
    8. Donors of plasma, organs, tissue or semen
    9. Infants born to mothers who are HBsAg positive
    10. Patients on Hemodialysis or cytotoxic or immunosuppressive therapy
    11. Patients at risk for exposing others to their blood or body fluids and hence requiring Postexposure Prophylaxis
    12. Liver Function Test Abnormality (specifically ALT and AST transaminase increases) of unknown reason
    13. Chou (2014) Ann Intern Med 161(1): 31-45 [PubMed]

III. Lab: Screening Protocol

  1. Step 1: Hepatitis B Surface Antigen (HBsAg)
    1. Positive: Go to Step 2
    2. Negative: May still represent Hepatitis B inactive carrier state
  2. Step 2: Differentiate Chronic Infection vs Immunity
    1. Hepatitis B Core Antibody
    2. Hepatitis B Surface Antibody (immune)

IV. Labs: Detectable Antigens

  1. Hepatitis B Surface Antigen: HBsAg
    1. Protein found on the surface of the Hepatitis BVirus
    2. First detectable agent in Acute Hepatitis B Infection
    3. Present as early as Incubation Period
    4. Found in high serum levels in both acute and Chronic Hepatitis B, and indicates the patient is infectious
  2. Hepatitis B Envelope Antigen: HBeAg
    1. Highly Infectious State
    2. Chronic Infection

V. Labs: Detectable Antibodies

  1. Hepatitis B Surface Antibody: xHBsAb IgG
    1. Prior Hepatitis B Infection with recovery and Immunity OR
    2. Prior Hepatitis B Vaccine with Immunity
  2. Hepatitis B Core Antibody: xHBcAb IgM and IgG
    1. Present at the time of Acute Hepatitis B symptoms
      1. Core IgM Antibody suggests recent Hepatitis B Infection within the last 6 months
      2. Core IgG Antibody persists lifelong (regardless of recovery)
    2. Covers Convalescent period
      1. Window between HBsAg clearance to xHBsAb conversion
      2. HBsAg negative during this time
  3. Hepatitis B Envelope Antibody: xHBeAb IgM and IgG
    1. Low Infectivity
    2. Predicts Hepatitis B Resolution

VI. Labs: Serology Interpretation

  1. Susceptible
    1. HBsAg negative
    2. xHBcAb negative
    3. xHBsAb negative
  2. Immune from natural Hepatitis B Infection
    1. HBsAg negative
    2. xHBcAb positive
    3. xHBsAb positive
  3. Immune from Hepatitis B Vaccine
    1. HBsAg negative
    2. xHBcAb negative
    3. xHBsAb positive
  4. Acute Hepatitis B Infection
    1. HBsAg positive
    2. xHBcAb IgM positive
    3. xHBcAb IgG positive
    4. xHBsAb negative
  5. Chronic Hepatitis B Infection
    1. HBsAg positive
    2. xHBcAb IgM negative
    3. xHBcAb IgG positive
    4. xHBsAb negative
  6. Indeterminate (resolved or resolving infection, False Positive xHBcAb, Chronic Hepatitis B)
    1. HBsAg negative
    2. xHBcAb positive
    3. xHBsAb negative

      2. Prolonged stage in newborns
      3. Asymptomatic (Serum Aminotransferases normal)
    2. Incubation (4-12 weeks)
    3. Late incubation (1-2 weeks)

  2. Stage 2: Immune Response
    1. Characteristics
      1. Immune response causes hepatic cell destruction
