Hepatitis B Surface Antigen (HBsAg) Test

What does a positive HBsAg result mean?

It means the Hepatitis B virus is currently present and active in your blood. Your doctor will order follow-up tests to determine whether it's a new (acute) infection, which often clears on its own, or a long-standing (chronic) one requiring ongoing management.

Can Hepatitis B be prevented?

Yes, an effective and widely available vaccine provides strong protection against Hepatitis B infection and is recommended as part of routine childhood immunization in many countries, as well as for at-risk adults.

Is chronic Hepatitis B curable?

While a complete cure is uncommon, chronic Hepatitis B can be effectively managed with antiviral medications that suppress the virus and significantly reduce the risk of long-term liver damage.
