Thank you very much! I checked in summer 2009, I still have antibody. Since I have too busy schedule, I was just wondeirng whehter I can skip the checkup, and directly do a boost shot? Thank you very much!
Also, how can I ask doctor to do the checkup for hepatitis B, since this is not rotine checkup? Normally the doctors here will refuse it since I could not tell them I have any syptom, and they don't understand why this is a big concern.
