What Is Hbsag Screening

HBsAg (Hepatitis B surface antigen) – A “positive” or “reactive” HBsAg test result means that the person is infected with hepatitis B. This test can detect the actual presence of the hepatitis B virus

What does HBsAg positive mean?

HBsAg (hepatitis B surface antigen): when this is “positive” or “reactive,” it means the person is currently infected with hepatitis B and is able to pass the infection on to others.

What does it mean if HBsAg is negative?

Your test results may not mean you have a problem. Ask your healthcare provider what your test results mean for you. Normal results are negative or nonreactive, meaning that no hepatitis B surface antigen was found. If your test is positive or reactive, it may mean you are actively infected with HBV.
