A Catholic friend of mine told me about a program through the Catholic church (open to all, not just Catholics) that will help with the cost of medications. I don't know if it also will help with testings or not, but it certainly wouldn't hurt to check this out, as well as checking with the pharmaceutical companies on your medications. If you get some of the medication costs covered, then the testing cost might be more 'doable' if you decide to go on and have it done.
