Hi shooter1029 and welcome to the forums.
Sorry to hear about
the problems you've been having and not finding the source of the problems.
A few issues can cause moderate elevations of liver tests, one is a condition referred to as fatty liver.
It is said the most common reason for fatty liver is due to alcohol abuse, diabetes or being overweight. It can also be caused from some medications.
A Prometheus test is used for people possibly having or suffering with chronic diseases and disorders. It is focused on the diagnosis of autoimmune, gastrointestinal and inflammatory diseases and disorders.
As for all tests to either diagnose or rule out Crohn's disease, please read this following thread where we have listed all tests and medications that are used to treat people with Crohn's disease.www.healingwell.com/community/default.aspx?f=17&m=2511307
The new GI you're seeing is on the right track but tests you'll see in that thread should also be included, you should bring them up as well.
I hope this is helpful, wish you the best of luck and please let us know your tests results once completed.
