What should I do to prepare for my Complete Gut Health Test and Symptom Screen?

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. For women before the menopause, it's best not to take your stool test while on your period as this can affect your FIT test (for bowel cancer).

What can the Complete Gut Health Test and Symptom Screen tell me?

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 condition 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).

Who should not use the Complete Gut Health Test and Symptom Screen?

We do not recommend using this test panel if you: are a child (17 years or under) are feeling acutely unwell - e.g. with a cold or flu or if you have new-onset (i.e. within the last few days) gut symptoms such as stomach abdominal pain or diarrhoea. 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.

Should I take the Complete Gut Health Test and Symptom Screen again?

If you have already taken this test panel to investigate the cause of gut symptoms, then we'd only recommend taking the panel again if you have developed new gut symptoms or your symptoms have changed.

A great service

A great service. Blood and faecal tests all completed inside a working week with a useful commentary and downloadable lab reports that will result in some treatment (finally) from my doctor. Very relieved. Highly recommended for the speed and clarity of the analysis.

What you need to know about our Complete Gut Health Test & Symptom Screen

Dr Claire Merrifield

Gut symptoms, such as diarrhoea, stomach pain and bloating, can really get in the way of living your life.

Our gut health test is based on guidelines from the British Society of Gastroenterology and includes blood and stool tests for all the main causes of gut symptoms in one go.

What's tested in your Complete Gut Health Test & Symptom Screen?

Our Complete Gut Health Test uses both blood and stool samples to look at 10 biomarkers checking for:

Gut Inflammation
Gut inflammation is a common cause of gut symptoms such as stomach pain and diarrhoea.
WHAT'S MEASURED?
- Faecal calprotectin is a sensitive marker of inflammation in the gut.
Bowel Cancer Risk
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.
WHAT'S MEASURED?
- The quantitative faecal immunochemical test (qFIT) detects blood in the stool which is a sensitive marker for bowel cancer.
Coeliac Disease Risk
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. We check for tissue transglutaminase IgA antibodies.
WHAT'S MEASURED?
- Raised levels of tissue transglutaminase antibodies are a marker of coeliac disease.
H. pylori Infection
Helicobacter pylori infection affects up to 1-in-5 of us in the UK. It causes stomach inflammation and ulcers which causes indigestion symptoms.
WHAT'S MEASURED?
- A biomarker for the presence of Helicobacter pylori in the gut.
Gut Bacteria & Parasites
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).
WHAT'S MEASURED?
- Salmonella is common bacterial infection from contaminated food.
- Shigella is spread by contaminated food or water and sometimes sexual contact.
- Campylobacter is one of the commonest bacterial gut infections.
- E. coli is a common bacteria that all of us have in our gut but some strains can produce a toxin causing gastroenteritis.
- Giardia is often spread by contaminated water - lakes, rivers or pools. It can cause chronic gut issues with bloating, cramps and diarrhoea.
- Cryptosporidium is one of the commonest parasite infections in the UK. It's often spread via contaminated 'recreational water' such as swimming pools.
Thyroid Health
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.
WHAT'S MEASURED?
- Thyroid stimulating hormone (TSH) stimulates the thyroid gland to make thyroid hormones. A low TSH indicates an overactive thyroid while a high TSH indicates an underactive thyroid.
