Baseline HBV Serologic Results

HBsAg anti-HBs anti-HBc Interpretation Recommended Action
(+) (-) (+) Chronic HBV infection Link to care for HBV treatment
(+) (-) IgM (+) Acute HBV infection Link to care for management and follow-up
(-) (+) (+) Resolved HBV infection Reassurance
(-) (+) (-) Immune to HBV Reassurance
(-) (-) (-) Susceptible to HBV (non immune) Vaccinate
(-) (-) (+)

"Isolated anti-HBc" may represent (1) prior HBV infection, (2) a false-positive test, (3) occult HBV infection, or (4) window phase of acute HBV infection

Expert consultation advised to determing optional further evaluation and management.
