Marker | Acute HBV Infection | Chronic HBV Infection | Prior HBV Infection† | Prior HBV Vaccination |
|---|---|---|---|---|
HBsAg | + | + | − | - |
Anti-HBs | − | − | + | + |
IgM anti-HBc | + | − | − | - |
IgG anti-HBc | − | + | ± | - |
HBeAg | ± | ± | − | - |
Anti-HBe | − | ± | ± | - |
HBV-DNA | + | + | − | - |
* Antibody to hepatitis D virus (anti-HDV) levels should be measured if serologic tests confirm HBV and infection is severe. | ||||
† Patients have had HBV infection and recovered. | ||||
Anti-HBc = antibody to hepatitis B core; anti-HBe = antibody to HBeAg; anti-HBs = antibody to HBsAg; HBeAg = hepatitis B e antigen; HBsAg = hepatitis B surface antigen; HBV = hepatitis B virus. | ||||
