    Test for liver cancer

    An alpha-fetoprotein (AFP) test may be done. If the AFP level is high, it may point to liver cancer.

    Follow-up visits

    If you have chronic infection, you will need to visit your doctor regularly. He or she will do blood tests to check your liver function and the activity of the virus in your body.

    Some of the tests can tell your doctor if the virus is multiplying in your liver. This raises your risk for chronic hepatitis.
