If you don't mind me asking, why are you paying out of pocket something that should be covered by insurance? Either private or medicaid, both would cover those costs for the tests you need. My brother was homless, living on the street, pan handling for booze money, and I got him set with medicaid, they did batteries of tests , got him on meds, and a place to live, with no cost to him.. it was difficult.. way more difficult than it should have been to get a disabled person on medicaid, but here in IL they are trying to keep as many peolpe off it as they can so they have resources for illegals.
