Hepatitis B Viral DNA - Topic Overview

The hepatitis B virus contains DNA. If DNA from the hepatitis B virus is found in your blood sample, then your doctor knows that the virus is multiplying.

  • You are contagious when HBV DNA is present. The higher the level of HBV DNA, the more contagious you are.
  • If you have a long-term (chronic) HBV infection, the presence of high levels of viral DNA means that you are at increased risk for liver damage and may want to consider treatment with medicines.
  • Testing for the amount of HBV DNA (viral load) is an important way to monitor the effectiveness of treatment for chronic HBV infection.
