is he chronic or acute ? when was he diagnosed ?
if acute then he may be in his last stages of clearance if chronic then boyfriend seems to be an inactive carrier. also called healthy carrier
monitoring every 6 months is ofcourse recommended with blood work testing for ALT AST . also an ultra sound is needed every 6-12 months depending on the opinion of his doctor.
transmition of illness is always possible though low risk with his current condition however, chornic hep B tends to have some flares in DNA levels at time.. may not happen but ofcourse always is a possibility with any hep B carrier no matter what their condition so i would be very cautious with my surrounding if i was him. as for you, unprotected sex isnt a very good idea. i would get tested and also vaccinated if you havent been before. if you are vaccinated with the heo B shots then you are immune and therefore you are in no danger of ever getting it.
he needs to lead a healthy life and a good diet , liver friendly diet.. i would stay away from alcohol all at once.
please do some reading online of coping and living with hep B for better understanding of the virus and its nature
good luck
to Another detail is that the s-alanine aminotransferase parameter (ALT/GPT) is 22 U/L (acceptable range)
thank you
