			My children had to be tested for TB because their father is Samoan, even though they had never been there.  It's a program set up for infants of islander parentage involving a chest xray.  It's got something to do with antibodies etc.  In Australia, TB is virtually unheard of whereas it's a problem in the pacific islands and apparently, children of those parents can be born with it (or no antibodies or something).  I don't know the full story because my kids were fine, but some kids are not.  At the time I was a zombie and didn't have time to think about informing myself.
 If you're really interested I'm sure you could find the answer to the question though.
