Patient's question:
How can you find out how you were infected with hepatitis B? You need to check the five hepatitis B items or check the DNA to find out.Doctor's answer:
Speculate how hepatitis B virus is transmitted, a preliminary judgment can be made through checking the five hepatitis B items, but it is only rough, and there are still some false negative and false positive patients. Checking hepatitis B virus DNA can more directly and accurately speculate how hepatitis B virus exists in the body and its activity, and is the "gold standard" for speculating whether hepatitis B virus has replicated. It can be certain that checking DNA is not a repeat check, but it is necessary, for the following reasons: 1. If a hepatitis B patient is "small three positive", it is generally said that this is the stage where the hepatitis B virus enters a non-replicating state, and the infectivity disappears or is very low, and the condition should also tend to stabilize. But the actual situation is not the case, sometimes the patient's transaminase levels still fluctuate repeatedly, and even jaundice reappears
