Hepatitis B Surface Antigen Test - More Information

The Hepatitis B Surface Antigen test, or HBsAg test, is a blood test that measures the level of this Hep B antigen in the blood.

The Hepatitis B surface antigen blood test is used to check for a Hepatitis B infection. After an exposure to Hep B through contact with the body fluids of an infected person, the blood will start showing evidence of the infection through measurable levels of Hep B surface antigen. In contrast to the Hepatitis B surface antibody titer which checks immunity secondary to a prior vaccination, this blood test is used to check for an actual infection.

In addition to checking for a Hepatitis B infection after an exposure, the HBsAg test has some other uses. This test is commonly used as part of a special MMA blood panel used to screen people who are fighting in combative sports like mixed martial arts or boxing prior to fighting.

To get an HBsAg test near, order online and get tested at the selected Quest Diagnostics lab. Once your HBsAg lab results are ready, they will be available for download. As can be seen on the sample HBsAg lab report, the HBsAg blood level will be reported as non-reactive if no hepatitis B surface antigen is detected by the lab.
