This is a test to whether or not movement through the bowel is normal or slow (delayed transit).
Do I need any preparation before-hand?
You will receive written instructions about the test beforehand. You should stop taking your normal laxatives or stool softeners at least 1 week before the test.
What does the test involve?
You will be sent three capsules through the post. Each capsule contains different shapes. You will be asked to take a capsule each day for 3 days. On the 5th day you will be asked to attend the x ray department where an x ray of your abdomen is taken.
What happens afterwards?
The x ray takes only a few minutes to complete. You will be able to go home straight afterwards and you can continue with all normal activities.
The radiologist will analyse the x ray and count the different shapes. From this they can work out colonic transit. A full report will be sent a full report to your consultant.
