a. Recovered & immune
b. Acute infection
c. Not infected & not immune
Interpretation of these Hepatitis B labs:
+ HBsAg
- Anti-HBs
+ IgM Anti-HBc
+ Anti-HBc
Acute Hepatitis B infection ≤ 6 mo duration
(immunity not yet developed)
+ HBsAg = infection
- Anti-HBs ≠ immunity
+ IgM Anti-HBc = acute ≤ 6 months
+ Anti-HBc = infection
Interpretation of these Hepatitis B labs:
- HBsAg
- Anti-HBs
- Anti-HBc
Never infected, never vaccinated for Hepatitis B
- HBsAg ≠ infection
- Anti-HBs ≠ immunity
- Anti-HBc ≠ infection
Interpretation of these Hepatitis B labs:
- HBsAg
+ Anti-HBs - Anti-HBc
Immunity from Hepatitis B vaccination
- HBsAg ≠ infection
+ Anti-HBs = immunity - Anti-HBc ≠ infection
Interpretation of these Hepatitis B labs:
+ HBsAg
- IgM Anti-HBc
+ Anti-HBc
- Anti-HBs
Chronic Hepatitis B infection
+ HBsAg = infection
- IgM Anti-HBc ≠ acute (≤ 6 months)
+ Anti-HBc = infection
- Anti-HBs ≠ immunity
Interpretation of these Hepatitis B labs:
- HBsAg
+ Anti-HBs
+ Anti-HBc
Immunity due to prior Hepatitis B infection
- HBsAg ≠ infection
+ Anti-HBs = immunity
+ Anti-HBc = infection
