Not all carriers of Hep B are contagious since there's a specific count of virus before it can infect somebody else, at least that's the explanation of the doctor. But just a question, is it really part of the medical test package for all expats here at Qatar? I'm just thinking, maybe it's only required to expats who are in the food handling businesses.

On the other hand, regarding the blood type, it's really totally different here, because back in my country I've been donating blood, and I am B+ and so far didn't hear any complaints that I have a different blood type, but when my medical results were released, I am surprised that my blood type here in Qatar is O+, maybe the weather changed my blood type LOL
