HBV serology markers: surface, core, and immunity pattern

Read first

Read HBsAg, anti-HBs, and anti-HBc together. This is a study anchor; real interpretation follows current lab algorithms and clinical context.

SusceptibleNo HBV markers detected

HBsAg negative, anti-HBs negative, anti-HBc negative. Study pattern: no marker of infection or immunity detected.

Immune patternAnti-HBs present

Anti-HBs positive suggests an immunity marker. Anti-HBc helps separate vaccine-style pattern from past infection pattern.

Acute patternHBsAg plus anti-HBc IgM

HBsAg positive with anti-HBc IgM positive is the classic acute-study pattern. Confirm and report according to the lab algorithm.

Key takeaways
  • HBV serology is read as a marker set.
  • Anti-HBs alone is not the same as anti-HBs plus anti-HBc.
  • Use study patterns, then follow the current lab algorithm.
Remember

Surface antigen asks current marker. Surface antibody asks immunity. Core antibody asks exposure history.
