I have a follow-up with my GI next month. I'm still having some minor to moderate symptoms (diarrhea, cramping, nausea) daily and I feel like we'll be discussing adding another drug or switching drugs. Before I do that, I want to make sure it's the Crohn's we're dealing with and not IBS or something related to having my gallbladder out. However, I do not want another scope (just had one in January). What are the blood tests that could show inflammation? Sed rate I think is one of them. I never get blood work done, even in an obvious flare, so I'm not sure what to ask for.
