Digestive Health

Stool test combining PCR microbiome mapping (60+ targets) with culture-based antimicrobial sensitivity testing. Identifies bacteria, fungi, parasites and worms at species level, then tests which antimicrobials each organism may respond to. Also includes calprotectin, zonulin, pancreatic elastase, secretory IgA and short-chain fatty acids.

Measures 26 amino acids (essential, non-essential and conditionally essential) from a finger-prick blood spot sample collected at home. Assesses protein metabolism, nutrient balance and amino acid availability across pathways including muscle repair, energy production and neurotransmitter synthesis.

Measures IgG antibodies against deamidated gliadin peptides for coeliac disease screening. Remains accurate when IgA deficiency makes the standard tTG-IgA test unreliable. Usually ordered alongside tTG-IgA as part of a coeliac serology panel.

Measures IgA antibodies against tissue transglutaminase, the recommended first-line blood test for coeliac disease screening. Also used to monitor dietary adherence in people already diagnosed with coeliac disease on a gluten-free diet.

Measures serum bile acids to assess liver function and bile flow. The primary marker for intrahepatic cholestasis of pregnancy (ICP). Outside pregnancy, used to investigate cholestasis and liver disease.

Measures unconjugated (indirect) bilirubin, produced when red blood cells are broken down before liver processing. Elevated levels suggest haemolysis or reduced liver processing capacity, as seen in haemolytic anaemia and Gilbert's syndrome.

Measures faecal calprotectin, a protein released by white blood cells during intestinal inflammation. Used to distinguish inflammatory bowel disease (IBD) from irritable bowel syndrome (IBS) and help guide whether further investigation such as colonoscopy is warranted.

Measures carcinoembryonic antigen (CEA), a tumour marker used to monitor colorectal cancer after treatment. Rising levels may indicate progression or recurrence. Not a screening test; levels can also be elevated in smokers and inflammatory conditions.

Screens for Clostridium difficile toxins A and B in stool using PCR. C. diff overgrows after antibiotic use and can cause colitis. At-home collection with prepaid return postage.

At-home stool test measuring 80+ gut organisms and digestive markers using quantitative PCR. Covers bacteria, parasites, yeasts, viruses, calprotectin, zonulin, and pancreatic elastase. Prepaid return satchel.

At-home stool test in four levels, each building on the last. Covers bacteria, yeasts, parasites, digestive function markers, antimicrobial sensitivities, and inflammation screening. Choose the level your practitioner recommends.

At-home PCR stool test screening for norovirus, rotavirus, adenovirus, astrovirus, and sapovirus. Clarifies whether a viral infection is causing gastroenteritis symptoms.

At-home stool test measuring essential minerals and toxic metals eliminated through the digestive system. Assesses nutrient absorption and whether metals such as mercury, lead, and aluminium are being cleared.

At-home stool test screening for hidden blood not visible to the naked eye. Recommended for routine bowel screening in adults over 45.

Detects antibodies against stomach parietal cells, which produce stomach acid and intrinsic factor needed for B12 absorption. Used to investigate pernicious anaemia, autoimmune gastritis, and unexplained B12 deficiency.

Measures gastrin, the stomach hormone that controls acid production. Used to investigate Zollinger-Ellison syndrome, H. pylori effects on gastric function, and long-term proton pump inhibitor use. Fasting required before collection.

Stool test using qPCR to measure beneficial, pathogenic, and opportunistic bacteria, parasites, yeasts, and digestive markers. Screens for microbial imbalances linked to bloating, irregular bowel habits, suspected infections, and other digestive symptoms.

Checks for active H. pylori infection by identifying bacterial proteins in a stool sample. Used for initial screening and to confirm eradication after antibiotic treatment. At-home collection kit.

Measures IgA antibody responses to 144 foods from a finger-prick blood spot. IgA is produced at mucosal surfaces like the gut lining, so elevated levels to specific foods may be relevant when investigating digestive symptoms and intestinal inflammation. Results are best interpreted with a healthcare provider.

Measures IgA antibody responses to 96 Asian cuisine foods from a finger-prick blood spot. Covers miso, rice varieties, seaweeds, and fermented condiments that standard Western panels often miss. Suited to people who regularly eat Asian food and have unexplained digestive symptoms.

Measures IgA antibody responses to 96 commonly consumed foods from a finger-prick blood spot. IgA reflects gut-level mucosal immune activity, making elevated results potentially relevant for digestive symptoms and intestinal inflammation.

Measures IgA antibody responses to 96 plant-based foods including legumes, grains, nuts, and seeds from a finger-prick blood spot. Suited to vegetarians and vegans with unexplained digestive symptoms that may relate to specific plant food triggers.

At-home blood spot test measuring IgG antibody levels to 240 foods. The broadest food panel available, covering common foods, uncommon varieties, and additives. IgG indicates immune exposure, not confirmed sensitivity.
