IBS Diagnosis
While there isn’t a single cure for IBS, many people are able to manage their symptoms through a personalised approach. This often includes dietary changes, stress management, and targeted treatments or medication. Gut health testing can play a key role in this process, helping to identify individual triggers and imbalances so you can find the strategies that work best for you.
Blood Tests
Celiac disease – by checking for anti-tissue transglutaminase antibodies
Anemia or infections – via a complete blood count (CBC)
Inflammation markers – such as C-reactive protein (CRP) or ESR, which may suggest inflammatory bowel disease (IBD)
Stool Tests
Calprotectin or lactoferrin – to look for inflammation that may indicate IBD rather than IBS
Fecal occult blood test – to check for hidden blood in the stool
Stool culture – to rule out infections caused by bacteria or parasites
Breath Tests
Lactose intolerance test – to detect problems digesting lactose
Fructose intolerance test – to check for fructose malabsorption
SIBO test – to identify small intestinal bacterial overgrowth
Hydrogen sulphide breath test – to detect specific bacteria in the gut
Other Investigations
Colonoscopy or sigmoidoscopy – if symptoms are severe or unusual, to rule out IBD, colorectal cancer, or microscopic colitis
Imaging tests – such as CT scans, MRIs, or abdominal ultrasounds to assess the intestines, gallbladder, or pancreas
