What tests diagnose irritable bowel syndrome?

ANSWER

A complete blood count can confirm IBS if your main symptom is diarrhea, but scientists are still studying how well it works when constipation is your chief complaint.

Other tests rule out different conditions that could be causing your symptoms:

�Removing foods, like dairy or a simple sugar called fructose, from your diet

�Blood test for signs of celiac disease

�Colonoscopy

�Lower GI series or barium enema

�Stool sample
