The "normal range" for hepatitis B depends on which test is being considered. The provided reference focuses on Hepatitis B surface antibody (anti-HBs).
Here's a breakdown:
-
Hepatitis B Surface Antibody (anti-HBs): This test measures antibodies that provide immunity against hepatitis B.
- Negative: Less than 5 mIU (milli-International Units). This indicates no immunity.
- Indeterminate: Between 5 and 12 mIU. This range requires repeat testing.
- Protective: More than 12 mIU. This indicates sufficient antibodies to protect against hepatitis B.
-
Hepatitis B Surface Antigen (HBsAg): This test determines if there is Hepatitis B in the system. If it is detected, the result is reactive or positive, meaning the person has Hepatitis B infection. If it is not detected, the result is non-reactive or negative, meaning the person does not have Hepatitis B infection.
-
Hepatitis B core antibody (anti-HBc): This test indicates previous or current Hepatitis B infection.
Result | Interpretation |
---|---|
Less than 5 mIU | Negative, indicates no immunity. |
5 - 12 mIU | Indeterminate, requires repeat testing. |
More than 12 mIU | Protective, indicates sufficient antibodies to protect against hepatitis B. |
