High-sensitive hepatitis B DNA test is indicated for patients who are minor triple positive as well as patients who are checking hepatitis B DNA less than 100 IU/mL, if the patient is planning to stop the medication, he can consider doing hepatitis B high-sensitive DNA test. Generally the normal value is actually less than 20IU/mL, if it is more than 20IU/mL, it is considered positive. For such cases, the patient only needs to check the hepatitis B DNA to see if the virus is replicating. If the virus is greater than 500 IU/mL, then the patient is considered to have a replication of the virus and needs to actively work with liver function to see if antiviral therapy is needed. If the patient has replication of the virus, and there is an increase in glutamic acid and glutamic oxalacetic aminotransferase, antiviral therapy can be considered at this time. If the patient is a chronic viral hepatitis B, you can consider oral lamivudine, adefovir and other drugs to actively antiviral treatment, but also can vegetation for antiviral treatment, interferon injection time is about six months to a year. Generally after a year, patients should review the possibility that some patients may turn into carriers as well as turn negative. If you have already turned negative, you need to promptly inject the hepatitis B vaccine to generate hepatitis B surface antibodies and carry out the body’s self-immune protection.
