A.P.
Hi, I was recently diagnosed with a wheat allergy. It's mild, but still...
Rather than going through the rigors of being tested, you might try going gluten free a period of time and see how it goes. I believe 6 weeks is sort of the minimum recommended, but I noticed a huge difference in only two weeks.
It sounds daunting, but once you get the hang of shopping, it's not that hard. Trader Joes has a good variety of gluten free stuff, and of course Whole Foods -- I actually saw some stuff at Target!
Rice pasta is easily available and (I think) tastes good. Bread can be tougher. I like Bob's Gluten Free Bread Mix. If you don't want to bake, TJ's has rice bread -- I highly recommend toasting it first (it's gummy).
Other than that, you'll find plenty of gluten free websites around. My favorite is Karina's Kitchen: Gluten Free Recipes.
