Colonic transit study

What’s the test for?

This test investigates how long it takes for faeces to pass through your bowel.

You may be referred for this test if you have been experiencing troublesome bowel problems such as constipation.

About the procedure

This study is a non-invasive test which evaluates how long it takes for faeces to pass through your bowel.

To do this, firstly five small capsules containing plastic markers are ingested. An X-ray of your abdomen will be then taken which will show up any markers left in your bowel.

If you are paying for this test yourself and not through private medical insurance, the cost will be £250.

How to prepare

We will send you five small capsules which need to be taken approximately four days (100 hours) prior to your appointment.

After ingesting the capsules:

  • You should not take any laxatives such as Fybogel, Lactulose, Movicol, Senna, Ex-Lax, Laxido etc.
  • You should not take any motility agents such as Prucalopride, Linaclotide, Lubiprostone etc.
  • Please do not use any suppositories or enemas such as glycerine.
  • You may continue to take all other essential medication.

What can be learned

This test evaluates how long it takes for faeces to pass through your bowel, which may provide an indication to the cause of your symptoms.

Following your test, your data will be analysed, and results written up into a report. The report will be sent to both you and your referring consultant/doctor, who will explain the results to you in a follow-up consultation.
