Hepatitis B surface antigen is a type of protein whose level rises in the blood of a patient with an active Hepatitis B infection.
The HBsAg blood test not only detects but also determines the type of infection to ensure that the patient is getting relevant treatment. Since Hepatitis B is communicable, a quicker and confirmed diagnosis is crucial to contain the infection without spreading it to people around you via blood or contact with the infected person's body fluids.
Unlike other Hepatitis B blood tests, which detect the antibodies, the HBsAg blood test determines the actual presence of the infecting Hepatitis B virus (HBV).
If the test results are positive or reactive, it indicates that the person is infected with the Hepatitis B virus.
The detection of the Hepatitis B surface antigens in the blood might take a few weeks after the infection initially starts in the blood. Since it's possible to transmit the HBV virus from one person to the other through blood, vaginal secretions, or seminal fluids.
In cases of acute HBV infection, the virus typically clears itself within six months, but some cases of the infection last over 6 months and are considered a chronic complication. The latter might lead to risks of liver cirrhosis, liver failure, liver damage, etc.
