Hepatitis B test results are mainly hepatitis B two-to-half, also called hepatitis B five, which is used to determine whether the infection or a rough estimate of the level of viral replication, including hepatitis B surface antigen, hepatitis B surface antibody, hepatitis B e antigen, hepatitis B e antibody and hepatitis B core antibody; the other test is called the hepatitis B viral DNA assay, which is used to accurately determine the level of replication of the hepatitis B virus. Hepatitis B surface antigen is a kind of hepatitis B virus shell material which is not infectious in itself, and a positive test suggests that there are intact virus particles, which is a sign of having been infected with the virus, and chronic hepatitis B patients are often persistently positive; the existence of hepatitis B surface antibody suggests that there is resistance to the hepatitis B virus, which is the protective antibody of the human body, and it is the main sign of whether hepatitis is recovered or not, as well as whether there is resistance; hepatitis B e antigen is a kind of antigen produced inside the hepatitis B virus, which is a kind of antigen produced inside the virus. Hepatitis B e antigen is an antigen produced within the hepatitis B virus, which is a sign of viral replication; Hepatitis B e antibody is a protein produced against the e antigen, and its positivity often indicates that it is in the recovery stage after infection, which is a sign of the cessation of viral replication; and Hepatitis B core antibody is a sign of the people who have been infected or are being infected. Hepatitis B virus DNA measurement is the most direct, specific and sensitive reliable quantitative indicators of HBV infection. positive HBVDNA suggests that there is HBV replication in the body, and the higher the level indicates that the virus replication is stronger and the more infectious. Hepatitis B five tests is the basic serologic test to determine whether the human body is infected with hepatitis B. Hepatitis B virus DNA is the test that accurately reflects the number of viruses and changes in the condition of the disease, and is the most commonly used serologic test for hepatitis B at present.
