Hello doctor. I have a few questions that I hope you can answer. Recently, I have been in love with a man, but later I found out that he has chronic hepatitis B. We had many deep kisses and had sex but used condoms. It was also my first relationship. After 1 week of sex, I tested negative for hepatitis B. So can you tell me when is the best time for me to get tested with accurate results? Thank you sincerely.

Answer
Hello. First, congrats on your negative result for hepatitis B. The incubation period of hepatitis B virus varies from 30-180 days, hepatitis B virus can be detected for an average of 4 weeks, varying from 1-9 weeks from when you are exposed.
Your case has used condoms, so the chance of infection is low. Deep kissing can also be contagious if your gums are damaged and your boyfriend bleeds during the kiss.
Therefore, after 1 month, you need to go to medical facilities for testing as well as hepatitis B vaccination if you do not have antibodies yet.
Thank you for your question to Vinmec Health System. Best regards.
