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.


  • 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.


  • 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.


  • 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.


  • 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).


  • 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.
