Hepatitis B is one of the types of hepatitis, also known as chronic viral hepatitis B. Hepatitis includes a variety of etiologic factors, such as viruses, drugs, and autoimmune factors, and viral hepatitis includes five types of hepatitis: hepatitis A, hepatitis B, hepatitis C, hepatitis D, and hepatitis E. Depending on the type of pathogen, the appropriate antigen and antibody tests are performed. Hepatitis B is tested mainly for hepatitis B surface antigen, hepatitis A and C mainly for antibodies, and hepatitis E and D as well. Therefore, if hepatitis is suspected, but you are not sure of the typing, you can have a major hepatitis 10 test. After confirming the diagnosis of hepatitis B, you can further improve the hepatitis B antibody test, if the IgM antibody is elevated, it may be a recent viral infection. IgG antibody is elevated, it may be due to previous infections, which may be acute, stable, or delayed, and further improve the liver function, the quantitative test of hepatitis B virus, and so on. Therefore, in the course of treatment, it is necessary to take into account whether the liver function is impaired, whether the virus is replicating, and other factors, and to formulate the appropriate treatment program.
