Hepatitis B DNA less than 500, if only in terms of this indicator, is normal below the lower limit of detection of 500. However, if the hepatitis B surface antigen is positive, in this case there may still be recurrent abnormal liver function and further examination of highly sensitive hepatitis B DNA is required. highly sensitive hepatitis B DNA can detect less than 20 viral loads, and the presence of steatohepatitis, autoimmune hepatitis, etc. also needs to be ruled out. If the liver function is normal and the hepatitis B DNA is less than 500, it indicates that the body is in good condition, indicating that the hepatitis B virus is not replicating. Hepatitis B virus carriers need to have regular checkups, get enough rest, and get a good night’s sleep. If you are not a carrier of hepatitis B virus and your hepatitis B surface antibody is negative, you can consider getting the hepatitis B vaccine to prevent hepatitis B infection.
