What are the tests for Crohn's disease?

Multiple. colonoscopy, endoscopy, capsule endoscopy. Imaging studies (usually CT scan or MRI). Blood tests ("IBD serologies", the most popular one is called the Prometheus panel).
Colonoscopy, imaging. There is no one perfect test to diagnose crohn's disease. In fact, many people have symptoms for almost two years before they are diagnosed. The chronic crampy abdominal pain and diarrhea usually lead to a colonoscopy. Sometime with a normal colonoscopy additional testing such as a small bowel series or ct scan enterocylsis can be used.

But you cannot make a blanket statement about all tests. Sorry. Read more...

Crohn's disease, I think I've found the cause. Would a Coombs test tell if a too strong immune system is the problem. There's obviously more to it.?

Wishful thinking. There is no single cause of crohn's disease. Picture the bottom of a funnel. Into the top goes your genetics, diet, the air you breathe, drugs your mother took while you were in utero, and possibly even the drugs you have taken in your lifetime, as well as other facors. Out of the bottom of this funnel comes astma, ulcers, and things like crohn's disease. Your way of managing stress may count. Read more...
