Is there financial assistance for unfunded allergen testing?

I have coeliac disease and lately I've been reacting a lot. I'm in a very strict no gluten household so it can only be ingredients at this point and it's things like flours and dried grains/pulses

I need to test quite a few things but 10 tests will cost me $344 excl. GST. Do my fellow kiwis know of any services that help fund this sort of thing? I don't want to keep letting friends, employer, etc down getting sick when I think it could possibly be avoided.
