Expert Q & A Answers About hepatitis test

My partner got hepatitis B over 15 years ago. Does she still have the virus?

My fiancée was diagnosed with hepatitis B when she was about 10 years old. Her most recent tests (15 years later) say she’s negative for the Australia antigen. In fact, over the last decade whenever she’s been tested, the results come back negative. Does this mean that she no longer has HBV? I’ve kissed her many times. Even though her tests come back negative, could I get HBV from kissing her? And after we get married, will our kids be affected by the virus?
