The Functional Gut Clinic is delighted to be the first centre in the UK to offer IBSchek* – a new blood test for IBS. A large proportion of IBS patients develop symptoms after a previous gastrointestinal infection (post infectious IBS). IBSchek is a new blood test that has been developed to look for biomarkers that identify whether a previous gut infection has caused a reaction, which could affect gut function.

IBSchek detects 2 biomarkers in the blood (anti-CdtB‡ and anti-vinculin) that are predictive of a previous gastroenteritis event. In a comprehensive clinical trial in more than 2,500 patients conducted in 180 centres around the U.S. IBSchek was found to be more commonly positive in IBS compared to patients with Crohn’s disease, ulcerative colitis, and celiac disease.

IBSchek therefore provides a positive diagnosis of an organic cause for IBS in a proportion of IBS patients.

*IBSchek is a Commonwealth Diagnostics International, Inc (CDI) product.

 Once a positive diagnosis of IBS is made, The Functional Gut Clinic can help to understand what affect IBS is having on your gut function and importantly what are the main factors contributing to your symptoms using targeted breath tests. (Hydrogen and Methane breath testing.)

We are also the UK’s leading centre offering the Wireless Motility Capsule (SmartPill) to assess whole gut motility and transit as well as profiling the pH in the colon which is a biomarker of bacterial fermentation (Caecal pH in IBS paper).
