I'm sorry I don't know anything about this. I just googled DQ Alpha Matching to see what it is. I find it fascinating that 2 unrelated adults can have "matching" DNA - has anyone ever explained to you how this happens and what it means to be matching (how much has to match)? This may sound stupid, but given how they use DNA to solve crimes etc., I would have thought that there are always substantial differences except with relatives.

Have you done your own research to see if labs here can do it? I know there's a FS in Sydney who is the expert on NK cells - may be it's worth contacting him to see if he does or knows anyone in Oz who does the DQ Alpha Matching test or maybe who could coordinate with the US lab to instruct a local lab to do the tests.
