I have no clue how this would be detected. One thing I've noticed is many pain treatment facilities do not do the test anymore because insurance in many cases do not pay for it. I've found 2 places that will do it for cash or charge, close to $1000. Every place I called the first thing they asked "is it a WC case" in which I responded "no, an SSDI case" and then seemed surprised and asked why would you even want this test done? My wife is going to do the test but it just seems another chunk of money down the drain. And more importantly if this test fails to help my wife at all, the feeling that we paid good money so she could go through much pain performing a test that can't gauge much as far as RSD is concerned.
