There are 2 prometheus tests. One to determine if you have IBD and the other to test if you can tolerate 6-MP. When I had a reaction to 6-MP my doctor ran both tests which did tell him that I did have Crohn's and not some strange other illness causing my new symptoms and that I was on the borderline of being able to tolerate 6-mp.
I hope that helps.
