I took the series of hepatitis shots. a few days after I took the last in the series I donated blood. I received a letter from the blood center that I tested positive for hepatitis B. Could this be in relation to the shot? My family MD is on vacation and I am very concerned.
Hi there, Thanks for posting your query. A person is said to positive for Hepatitis B if his blood is positive for Bag and Anti HBC antibodies. When a person donates blood these two are also tested to see if he is infected with hepatitis B virus. Hepatitis B shots do not lead positive Bag and Antiphon. The only marker that becomes positive after hepatitis B shots is antics. Presence of more than 10 IU/ml of antics indicates you are protected against hepatitis B. In your case it looks like you are positive for Bag. It is likely that you had this infection even before you got the hepatitis shots. So the reason for your positive hepatitis B is past infection and not the hepatitis shots. Is this answer helpful?
