Hepatitis B normal value, generally refers to the patient blood check hepatitis B DNA normal value, hepatitis B DNA check value is less than 500U/mL, more do not consider the patient virus has replication. If the value of hepatitis B DNA test is less than 500U/mL, it is not considered that the patient has virus replication. If the value is greater than 500U/mL, it should be considered that the patient has virus replication, and at this time the patient needs to take blood to check the liver function to see if there is any elevation of glutamic acid and glutamic oxal transaminase. If there is an elevation of ghrelin and ghrelin, then the patient is considered to be in the window period of viral replication. Patients can actively consider antiviral treatment, and can choose to take oral lamivudine, adefovir, entecavir and other drugs to actively take oral antiviral treatment. Generally, long-term medication is required, and should not be stopped in the middle of the course. After stopping the medication, the patient may experience withdrawal symptoms, which may lead to the rebound of viral replication and the rapid deterioration of liver function. In addition, patients can also consider interferon injection for antiviral treatment, which can be injected for about half a year to one year, and after interferon injection, some patients may become negative or carriers.
