Mine won't Since she gave me the ME diagnosis she has refused to give me any tests not ordered by a consultant, and has refused in all but two cases to refer me to any. Even to get a diabetes diagnosis I had to buy both urine test strips and a BG meter - she tested once, before I was diagnosed with ME, and then refused to test again, even using a BG monitor in the surgery, until I bought her evidence. I did once manage to get her to do a TSH test, which came back as "normal" according to her, pity that I hadn't asked for one, I asked for testing for parathyroidism - as I found out my father had it, and I'd noticed calcium channel blockers did weird things to me, my thinking was probably wrong, but I considered it worth checking. So...we have an interesting but not very enlightening relationship. She is primarily there IMO to supply me with painkillers, she's no use for anything else. Even with my type 2 diabetes she does nothing apart from book appointments she knows it's unlikely I can attend (presumably she gets paid for each), simply ignoring when I informed her I had become severely intolerant to the meds she insisted I took, I was not offered any other options by her, a diabetes nurse from the hospital took a look at my results, referred me onwards herself, and they fixed the problem (well apart from one side effect but I'm still trying to work around that). She is not a good GP (IMO) But yes...it's a lot of money, for something that will possibly tell me nothing useful, I'm hoping for "certainty", one way or the other, and an idea if using NDT or importing T3 is a good idea, whilst I would probably send my GP a copy of the results, if they say anything interesting, I'm not expecting her to actually do anything useful with them.
