Gut symptoms, such as diarrhoea, stomach pain and bloating, can really get in the way of living your life. Plus, not knowing what’s causing them can leave you worried and frustrated, making symptoms worse.
We’ll help you get to the bottom of your symptoms and reduce those worries. Our Full Gut Symptom Screen is based on guidelines from the British Society of Gastroenterology and tests for all the main causes of your gut symptoms in one go. Whether we pick up a specific disorder or rule them out, you’re taking the all-important first step to understanding and sorting your symptoms.
Our Complete Gut Health Test and Symptom Screen is specifically designed to help you if you have undiagnosed gut symptoms such as:
Gut inflammation is a common cause of gut symptoms such as stomach pain and diarrhoea.
Bowel cancer affects 1-in-15 of us and the main symptoms are a change in bowel habit, stomach pain and blood in the stool. A qFIT test is the gold-standard test to check for blood in the stool.
Coeliac disease affects 1% of the population and most people don't know they have it. It causes indigestion, stomach pain, diarrhoea and weight loss.
Helicobacter pylori infection affects up to 1-in-5 of us in the UK. It causes stomach inflammation and ulcers which causes indigestion symptoms.
Gut infections with bacteria and parasites can cause a variety of gut symptoms. Gut infections are generally more common if you've been travelling abroad or in contact with someone else who's had gut symptoms. We use PCR to test specifically for Giardia, Cryptosporidia, Salmonella, Shigella, Campylobacter and toxic E. coli (VTEC).
Thyroid disease is the one of the commonest autoimmune diseases in the UK. An overactive thyroid causes diarrhoea and weight loss while an underactive thyroid causes constipation and weight gain.
Collect your sample at home or visit a clinic.
Use the included envelope to post your sample back to our UKAS-accredited lab (The Doctors Laboratory) for analysis.
We'll deliver your results to your dashboard. Every result is explained so you're in control.
You can also track your results over time.
Our experts will give you a report so you'll know what your results mean.
We'll highlight how you can use your results to understand symptoms, pick up health problems early and take action.
Please get in touch if you have any other questions about our tests.
Proton pump inhibitor (PPI) medication, such as lansoprazole or omeprazole can make the H. pylori stool test less accurate. If you take PPIs you should stop this at least 2 weeks before testing. It is usually safe to stop this medication for a short period of time, but if you're not sure, speak to your prescriber.
The test for coeliac disease will not be accurate if you do not have gluten in your diet. Make sure your diet contains wheat, barley or rye in the 6 weeks before testing for accurate results.
It's best not to take your stool test while on your period as this can affect your FIT test (for bowel cancer).
This test panel can tell you if you have markers in the blood or stool of a number of important and/or common diseases that can cause gut symptoms. Positive results can indicate a disease that may require treatment. Negative results make it much less likely that you have a disease causing your symptoms and it's much more likely that you have a condition like irritable bowel syndrome (IBS).
We do not recommend using this test panel if you:
If you have a known medical condition that directly affects the bowel, such as inflammatory bowel disease or bowel cancer, then this test panel may not be useful.
If you're unsure if you should use this test panel, please contact us for advice.
For most people, there is no benefit in repeating medical tests frequently unless you have specific medical conditions or take medicines that require monitoring.
If you have already taken this test panel to investigate the cause of gut symptoms, then we only recommend taking the panel again if you have developed new gut symptoms or your symptoms have changed.
Your results will be reviewed by one of our doctors. They will write a report explaining what your results mean for you. They will also tell you if there are any specific actions you should take, like seeing a healthcare professional, considering further tests or making changes to your lifestyle.
