[|Human|] My father went for blood screening last month because he keep on having mild to high fever in space of short time. the result came out ok except the Hep B screening. The doctor said he is having Hepatitis B infection and need 3 vaccination jab.the result are HBs Antigen - nonreactive , HBs antiboby 80MIU/ML witChatDoctorment booster dose might be considered.From my knowledge when surface antigen non reactive, its mean my father doesnt have HepB infection. and the presence of surface antibody means he either have the infection before or have had vaccination done in the past.If that is true, is my father now considered as the Hep B carrier? He is 73 yrs old and he love to share food with his grandchild.
[|AI|]  Thanks for positing your query to Chat Doctor . As understand you are worried about your son. So I just want to explain to you that Hepatitis carrier are always found positive with Hepatitis B surface antigen along with Egg antibody for Hepatitis B core antigen, so your father is not carrier, and again you are right as presence of HBS antibody indicate past infection or due to vaccination. So no need to worry about your father and son both . Hope I have solved your query. Feel free to contact me. Regards Chat Doctor.
