Description:
The Hepatitis B surface antigen (HBsAg) test is a blood test used to detect the presence of the Hepatitis B virus (HBV) in the body. It is one of the primary tests for diagnosing acute or chronic Hepatitis B infection.
Key Points:
A positive HBsAg test indicates an active HBV infection (either acute or chronic).
A negative HBsAg test means the person is not currently infected with HBV.
If HBsAg remains positive for more than six months, it suggests chronic hepatitis B.
This test is commonly used for screening, diagnosis, and blood donor testing.
The test is often combined with other HBV markers (e.g., anti-HBs, HBeAg) for a complete hepatitis B profile.
Who Should Get Tested?
Pregnant women
Healthcare workers
Individuals with liver disease symptoms
Those at high risk of HBV exposure (e.g., unprotected sex, shared needles)
Before receiving immunosuppressive therapy
Vaccination against hepatitis B can prevent infection and the spread of the virus.
