Patient's question:
Previously, the five hepatitis B tests were negative, and except for antibodies, I don't know what the reason was for getting infected. Upon careful examination, it was found to be 245 positive. A year later, when I rechecked, it turned into a small second positive. I want to ask the doctor if a small second positive can turn negative? It's said that if you have antibodies, you won't get infected, right? How come I still got infected?Doctor's answer:
From your description, it may be due to the antibody titer increasing over time, thereby losing the ability to combat the hepatitis B virus, leading to infection with the hepatitis B virus. The positivity of items 2.4.5 indicates that you are in the recovery period from hepatitis B. Under the condition of increased viral load copies, it is possible to transform into the hepatitis B "minor positive" state. It is recommended to conduct further liver function tests and a thorough check of viral load. If the viral load is high, timely antiviral drug treatment is necessary.
