Whether or not to test for Hepatitis B in a physical exam needs to be determined on a case-by-case basis. Hepatitis B testing is required for physicals in specialties, such as preschool, flight, and food-related professions. Other professional physicals generally do not require a Hepatitis B test. Individuals who need a physical examination to check for hepatitis B can choose the appropriate physical examination program according to their own physical condition. For hepatitis B patients, virus quantification, liver function, ultrasound, and blood tests are the most basic indicators for daily monitoring. For positive hepatitis B carriers, further liver function tests are recommended. If liver function abnormalities are also present, hepatoprotective and antiviral therapy is needed. Hepatitis B is checked by blood sampling. The day before the physical examination, you should eat a light diet. On the day of the physical examination, you should have an empty stomach and go to the designated place for the relevant examination. Hepatitis B physical examination needs to check Hepatitis B virus DNA, liver ultrasound, liver function and so on. If any abnormality is found, other items need to be checked according to the doctor’s advice.
