Regarding the tests accuracy, Prometheus claims it to be 92% accurate (
www.prnewswire.com/news-releases/prometheus-launches-prometheusr-ibd-serology-7-55900847.html). Of course, how they came to that number...
I had the Prometheus test done in 2009 and it came back positive for IBD leaning toward UC. This is strange though, since I have never had any inflammation in my colon; rather it has only ever been in my terminal ileum and stomach. So personally, I don't really put my faith in the results.
Speaking of doctors: Back when I had that test done, my GI at the time did a colonoscopy because I was having symptoms of a flare. The colonoscopy came back clean, so (of course!) my GI said he didn't think I had Crohn's at all, even though he had my previous GI's notes with all the information from the pill cam and colonoscopy (including biopsies) that diagnosed me. In his opinion, because there were no granulomas, it must have been something else (because you MUST have granulomas to have Crohn's). Ugh. Thank goodness I was relatively well during the time I lived in his area.
Personally, I would try to find a GI *you* trust and who you think is doing what's best for you, not just someone who your mom trusts. Your mom doesn't know everything going on with you and she can't make the best decisions for you when it comes to your health. If you're stuck with this one (are you sure he's the only GI in 3.5 hours?) then be
open and honest, make lists of things you want to talk about
him with, and make sure he sees you as an adult and treats you as an adult.
I hope everything works out. You can and will get through this.
