Patient's question:
My wife is now three months pregnant. Today, when she went to the hospital to register for prenatal care and have a check-up, it was found that she has hepatitis B surface antigen (HBsAg positive), but her liver function is normal. She is very worried about it possibly being transmitted to the child. Can a person with HBsAg positive and normal liver function transmit the infection to the child?Doctor's answer:
How to carefully check if liver function is normal in a small hepatitis B positive case, it can basically confirm that liver cells have not been damaged again. However, if there are pathogens inside the liver cells, it is necessary to check the virus count to determine if there is infectivity. Only based on the result of the hepatitis B virus DNA, if the result is above 500, there is a possibility of infection. If the test result is below 500 and above the detection threshold, it is normal.
