The likelihood of a false negative for Hepatitis B surface antigen is generally low. Hepatitis B surface antigen is usually diagnosed with the help of a hepatitis B DNA test. Since this test is a characteristic test, there is no need to worry about false negative results. If the Hepatitis B surface antigen test result is negative, it is a normal sign and does not require special treatment. When hepatitis B surface antigen turns negative, it means that the hepatitis B virus has been eliminated, which means that the hepatitis B disease has been cured. However, clinically, you can’t rely on the hepatitis B surface antigen alone to diagnose, but also need to combine with other indicators of hepatitis B five, as well as ultrasound of the liver, liver function, and HBV-DNA to make a comprehensive evaluation. In addition, Hepatitis B is a relatively harmful disease, once the diagnosis is clear, it is recommended that patients need to actively accept treatment.
