If I took a sweat test for Crohn's diease and tested positive, does this mean I have crohn's?

If I took a sweat test for Crohn's diease and tested positive, does this mean I have crohn's?

Double check: I know of no sweat test for crohn's disease. Generally, crohn's is diagnosed by a colonoscopy and biopsy, or a video capsule endoscopy. Double check what you have been told, as there is a sweat test for cystic fibrosis. ...Read more

Missleading: There's is not a specific disgnostic test that's says for certainty you either do have or do not have or don't have this disease. The disgnoses is based on symptoms, multiple blood tests colonoscopy/ ugi, and biopsy results. ...Read more

Why does test show I have Crohn's and the doctor says I have ibs?

Need biopsies: There are blood tests that can help distinguish between crohn's, ulcerative colitis and ibs but these are not the most dependable. The gold standard is colonoscopy with biopsies. ...Read more

Are blood test 100% accurate for judging crohns flare ups? I feel like I have had the worst flare up ever. Diarrhea, blood in stool, nausea, pain. Everything negative. Help?

Are blood test 100% accurate for judging crohns flare ups? I feel like I have had the worst flare up ever. Diarrhea, blood in stool, nausea, pain. Everything negative. Help?

No: There is no test that I know of that is 100% accurate for any medical condition. There is no specific test that will rule in or rule out Crohn's flare ups. Commonly used, ESR and CRP are non specific inflammation tests. Patients with Crohn's still develop gastroenteritis or colitis like diseases that are commonly assigned and treated as flare ups. ...Read more

In what way does Crohn's disease alter test results? False positives or false negatives?

In what way does Crohn's disease alter test results? False positives or false negatives?

Too open ended: We cannot answer the question without further consideration of the type of tests you are referring to. There are definitely some tests that can be falsely elevated if you have crohn's disease. The one that comes to mind is the blood test for celiac disease (ttg) which can be elevated in crohn's. But you cannot make a blanket statement about all tests. Sorry. ...Read more

Can you still have Crohn's if your colonoscopy test is negative?

Can you still have Crohn's if your colonoscopy test is negative?

Yes: Crohn's disease can affect any part of the GI tract from the mouth to the anus. In many patients, the colon is not involved, and so a colonoscopy will not reveal any abnormal findings. A diagnosis of crohn's disease is made using a combination of symptoms, physical exam findings, blood tests, imaging tests, and other clinical tests. ...Read more

What blood tests help in the diagnosis of Crohn's disease?

Not a bloodwork call: Routine labs reflect only the illness (malabsorption, inflammation) and are nonspecific. A pricey antibody panel is offered to perhaps support and/or prognosticate the diagnosis. The diagnosis is made on imaging and perhaps biopsy or (worst case) resected surgical specimen. ...Read more

Wrong assumption: Of course you can have normal WBC with Crohn's, especially if well controlled on therapy. Sit with your gastroenterologist to be sure you understand your disease and its treatment. ...Read more
