What is the HBV DNA of healthy people? Will there be DNA value? I went to check the five items of hepatitis B, and the result was 245 positive, and the others were negative!

1. At present, HBV-DNA is quantitatively detected. Because of the sensitivity of detection technology and many influencing factors, nonspecific amplification often occurs. Therefore, even normal people who have not been infected with hepatitis B virus rarely end up with 0. Therefore, it is generally expressed as less than 1000 or less than 500, instead of negative or positive, in order to reduce this non-specific amplification to the subject. As long as the result is less than 1000 or 500, it is normal, and the test results below this number need not be entangled.

2. Hepatitis B 245 means that I accidentally touched the hepatitis B virus. Fortunately, under the action of the autoimmune system, hepatitis B virus has been completely eliminated, resulting in surface antibodies and two other antibodies, which is equivalent to an accidental vaccination of hepatitis B vaccine. However, in this natural infection, in addition to surface antibodies, E antibodies and core antibodies are also positive, because hepatitis B virus contains not only surface antigens, but also E antigens and core antigens.

3. Clinically, it is found that most of this situation is healthy and no longer contagious. But there are also a few people who are recessive infection caused by virus mutation, which will be contagious. You can do HBV DNA identification. If HBV-DNA is less than 1000 or 500, nothing will happen.
