Stool Sample
Since irritable bowel syndrome would cause some digestive issues, a stool sample can be used to diagnose it. The doctor might give you a small container to hold a small stool sample. This will be then used for checking the presence of any diseases or infections that would cause irritable bowel syndrome. In addition, he or she might examine whether there is blood in the stool. You should also tell your doctor some changes in your stool. Do your stools look soft like diarrhea? Do you see any clear mucus around or on the stool? All of these are typical symptoms of irritable bowel syndrome. [3]
