Do I need to be tested for hepatitis B before getting the vaccination? - Hepatitis B for Patients
In some cases your provider may decide to test your blood for antibodies to hepatitis B, but this is not mandatory for everyone.
If the test shows that you have antibodies to hepatitis B, it means that you were infected with hepatitis B in the past, or you were previously vaccinated for hepatitis B. If you already have antibodies to hepatitis B, you don't need to get the hepatitis B vaccination.
