I have also recently been offered a job in Qatar, and my wife is a Hep B carrier. The most recent information above seems to point to the fact that she will be OK for a residency permit, provided that she is not working in medical/food fields. (In fact, it is not the intention that she will be working at all, initially at least).

Whilst the above info certainly seems more authoritative than info I have previosuly seen, it seems there is no definitive evidence (e.g. links on the internet).

Can anyone assist further? The way it looks now, we will need to take the medicals before I resign my current job.
