Hepatitis B DNA quantitative control is based on the amount of Hepatitis B virus in the blood to assess whether or not the patient is infectious and how actively the virus is replicating. Hepatitis B DNA quantification is a test that is performed after it has been determined that a person has been infected with the Hepatitis B virus. The higher the Hepatitis B DNA quantification, the more contagious the patient is. It indicates that the patient has a high number of hepatitis B viruses in his body and is replicating rapidly. Since the Hepatitis B DNA quantitative results are numerical and not “normal/abnormal”, it is important to know the control reference range of the test performed. Generally speaking, the quantification of hepatitis B virus DNA is less than 10^3 copies, which corresponds to the normal value of hepatitis B virus DNA quantification, and there is no need for treatment if the patient does not have liver function abnormalities. 10^3 copies
