The total time that food goes from the mouth to the anus through the digestive system is the transit time of food in the intestine. Sometimes, it is measured only as food travels through the large intestine. This time is called Colon Transit (CTT). Intestinal transit test is a type of radiographic test that measures the time required for food to pass through the digestive tract. The common way to perform this test is to swallow the clone marker through the mouth (food intake), which is usually done after the stomach and duodenal test. The intestinal transit time depends on the type of food and the amount of drink consumed.

Usually, studying the CTT allows the doctor to recognize the normal or slow process of the colon. The remarkable thing about this test is that if it is performed at different ages, the normal limit of transit is different. The most important benefit of this test is that it is possible to determine if a person has chronic constipation or if the number of bowel movements has decreased. If the transit time is normal after checking the CTT, there is no need to continue checking; because this person has reduced the number of bowel movements. Also, if the person has a slow movement of the colon. By performing this test, it can be determined which part has led to slow colon movement.
