Depending on the configuration of the hospital department, the hepatitis B test can be ordered from the Department of Liver Diseases, the Department of Infectious Diseases or the Department of General Internal Medicine, which will issue a laboratory application form and then draw blood for the appropriate test. Hepatitis B five tests are commonly used clinical tests, mainly referring to surface antigen, surface antibody, e antigen, e antibody and core antibody. The Hepatitis B test can screen for hepatitis B virus infection and assess antibody production after hepatitis B vaccination. Infectious disease departments are generally available in general hospitals above the second level, so you can go to the infectious disease department for the hepatitis B tests. In addition, some hospitals may have a hepatology department, which can also apply for related tests. Some hospitals may require a visit to the gastroenterology department or other departments for the test. For pediatric patients who want to check hepatitis B five, they can register and visit the pediatric internal medicine department, and then have the appropriate tests.
