SeHCAT study
SeHCAT scan
A drug used in a clinical test to diagnose bile salt malabsorption, a common cause of chronic diarrhoea
About
A SeHCAT study is used to diagnose bile salt malabsorption. It used to investigate the symptoms of irritable bowel syndrome (IBS) or chronic diarrhoea.
For the test, you swallow a radioactive capsule with water. You will be exposed to a small, safe level of radiation.
Once you've successfully swallowed and ingested the capsule (around two hours later), your consultant will scan your abdomen. The test will need to be repeated one week later. This will help the consultant to make a diagnosis.
This procedure is painless so you won't need anaesthetic. And the entire procedure takes approximately 15 minutes.
Your consultant will let you know exactly what you need to do to prepare - you should avoid having breakfast on the morning of the test. They will fully explain the process to you and let you know if there are any risks and side effects involved.
