Hepatitis B five clinically also called hepatitis B three system, and liver function test is completely different from the two clinical examination. Hepatitis B five is to check whether the patient has chronic viral hepatitis B, as well as to check whether the patient is chronic viral hepatitis B is triple-positive, or triple-positive, triple-positive patients are more likely to suggest that the patient has viral replication, triple-positive patients are more likely to suggest that the patient does not have viral replication. Liver function is to see the overall state of the patient’s liver after drawing blood on an empty stomach, whether there is liver insufficiency, as well as hepatocellular necrosis, and whether the patient is combined with jaundice. If direct bilirubin is elevated, jaundice is usually due to obstructive factors. If indirect bilirubin is predominantly elevated, jaundice is more likely to be caused by hepatocellular necrosis. Therefore, the purpose of hepatitis B five tests and liver function tests are different, and the treatments given after the tests are also different. If the patient has viral replication, and the liver function of glutamic acid and glutamic oxal transaminase is elevated, it is considered that the patient needs active antiviral treatment.
