Hepatitis B Surface Antigen Test

Infectious Disease Testing




The Hepatitis B Surface Antigen (HBsAg) test is a blood test that detects the presence of a protein on the surface of the Hepatitis B virus. This test is used to diagnose acute or chronic Hepatitis B infection.

A positive HBsAg test result indicates current infection with the Hepatitis B virus. It is important to follow up with additional testing to determine the stage of the infection and to decide on appropriate treatment.

If you have been exposed to the Hepatitis B virus or are at increased risk of infection, it is recommended to get tested regularly for HBsAg to monitor your status and protect your health.
