How to Work Up Functional Diarrhea

American Gastro Society has these guidelines for how to work up functional diarrhea, which I think is a good place to start instead of what I talked about. Celiac testing is actually a strong recommendation. The third test that has recently come out was added in the 2019 AGA guidelines for workup of functional diarrhea. It's going to be for fecal biolacid testing. And when we kind of get into, I guess this is probably outside this scope, but for a lot of our patients who have IBD but who are in remission, but still have diarrhea, then that becomes really important for us to hone down.
