Test Overview
Hepatitis B tests are blood tests that show whether you have an active hepatitis B infection. The tests can also show if you had the infection in the past.
The tests look for different signs of infection:
- Antigens, which are made by bacteria or viruses.
- Antibodies, which are made by the body to fight infection.
- Hepatitis B DNA, which is the virus's genetic material.
Hepatitis antibodies can take weeks or months to develop. So an infected person may test negative early in the infection.
