I kind of live on a different continent but if your naturpaths are like the ones here then I would imagine it shouldn't be too hard to find one to do the test. A naturpath is more likely to believe you and I don't see why they wouldn't order a test if you really wanted it. I actually emailed an ND asking if he or he knew a doctor that would do a stomach acid test on me and he reccomended someone and I figured from that, that doctor would be open to doing other tests as well.
