The colonic transit time test is a diagnostic procedure that offers information as to how long it takes for food to travel through your digestive system. It is used to gain a better understanding of how well your large intestine is functioning in terms of moving stool along.
The test involves swallowing capsules that contain markers that can be seen in an X-ray. X-rays of your lower abdomen will be taken on subsequent days. As there are various forms of this test, the number of capsules and the number of days in which X-rays are taken will vary.
