Your healthcare provider may order other blood tests to look for HBV. These tests can look for antigens on the surface, envelope, and core of the virus, as well as the antibodies to these antigens. The symptoms of all 5 hepatitis infections are much the same. So this blood test is often done along with other hepatitis blood tests to tell your provider which type of virus and what stage of infection you may have.
Your healthcare provider may also order a series of blood tests called a hepatitis B monitoring panel to see if your infection is getting better. Test results may vary depending on your age, gender, health history, the method used for the test, and other things. Your test results may not mean you have a problem. Ask your healthcare provider what your test results mean for you. Normal results are negative or nonreactive, meaning that no hepatitis B surface antigen was found.
If your test is positive or reactive, it may mean you are actively infected with HBV. In most cases this means that you will recover within 6 months. If you recover, you will have immunity from the virus and will not be able to pass the virus to others.
A positive test may also mean you have chronic hepatitis B infection. If you don't recover in 6 months, the virus may stay in your blood and cause liver problems. You can also infect others. Your healthcare provider may give you medicines if you don't recover after 6 months.
The test is done with a blood sample. A needle is used to draw blood from a vein in your arm or hand. Having a blood test with a needle carries some risks. These include bleeding, infection, bruising, and feeling lightheaded. When the needle pricks your arm or hand, you may feel a slight sting or pain. Afterward, the site may be sore. You don't need to prepare for this test. Be sure your healthcare provider knows about all medicines, herbs, vitamins, and supplements you are taking.
