A blood test measuring IgA and IgG antibodies used to help assess coeliac disease and gluten sensitivity, alongside tissue transglutaminase IgA. Suited to people investigating unexplained gut symptoms possibly linked to gluten.
3 biomarkers as listed by London Medical Laboratory.
This profile measures total Immunoglobulin A, IgG antibodies to deamidated gliadin, and tissue transglutaminase IgA. These antibodies are commonly raised in coeliac disease, where the immune system reacts to gluten, and checking total IgA alongside the specific antibodies helps rule out a false negative in people who are naturally low in IgA. The panel can also flag patterns associated with non-coeliac gluten sensitivity.
Three markers is above the median of 1 across the 11 coeliac tests we track, putting this ahead of several single-marker screens such as Bluecrest Wellness's Coeliac Disease test at £65. At £124, it is also cheaper than the £169 group median, and considerably less than Better2Know's own Coeliac/Gluten Sensitivity Profile, which tests one marker for £295.
The combination of above-median depth and below-median price drives a solid clinical depth and value for money score. Collection convenience is lower than London Medical Laboratory's other tests because this one needs a venous blood draw at a clinic rather than a finger-prick kit, with no at-home option. Trust signals and results and follow-up reflect the same CQC registration and doctor-reviewed report as the rest of the range.
This suits you if you have ongoing digestive symptoms, such as bloating, diarrhoea or unexplained weight change, and want to check antibody markers associated with coeliac disease or gluten sensitivity before making dietary changes. It's worth doing this while still eating gluten, since antibody levels can drop once gluten is removed from the diet.
If you want a lower-cost initial check, Bluecrest Wellness's Coeliac Disease test covers 1 marker for £65, though with less coverage than the 3 markers here. Any positive or unclear result should be followed up with a GP, since this test does not itself diagnose coeliac disease.
This test requires a venous blood draw, either at a partner clinic (plus £35) or via a home visit from a phlebotomist (plus £80); it is not available as a finger-prick kit. The lab measures the three antibody markers, and a doctor reviews the results before you receive your report, typically within 2 days.
This profile checks three antibody markers associated with coeliac disease and gluten sensitivity: total IgA, IgG gliadin antibodies and tissue transglutaminase IgA. At £124 it costs less than the £169 median across the coeliac tests we compare it with, including Better2Know's own Coeliac/Gluten Sensitivity Profile at £295. The main limitation is that it requires a venous blood draw rather than a finger-prick sample.
The listing publishes a detailed description, the full biomarker list, a stated turnaround, clear collection options, the sample type; it does not state what the report looks like.
3 biomarkers against a median of 1 across the 11 tests in its comparison group.
A finger-prick sample you take at home; with a venous or clinic option as well; results in around 2 days, well ahead of the gut health norm of 5.
Results are reviewed by a doctor; the provider does not describe the report format.
No Trustpilot rating on record; CQC registered; doctor review as standard.
£124.00 against a comparison-group median of £169.00 (-27%).

Broad coeliac panel priced well below rivals
A 4-antibody blood panel used to assess for coeliac disease, covering tissue transglutaminase, endomysial and deamidated gliadin antibodies plus total IgA, for people with ongoing gut symptoms after eating gluten.
Broad symptom screen priced above the coeliac group median
A 4-marker blood and stool panel screening for coeliac antibodies, gut inflammation and H. pylori infection, for people with IBS-type symptoms who want other common causes checked alongside a GP assessment.
Market-median price, lighter on markers than some rivals
Checks for antibodies linked to the body's immune response to gluten, plus total IgA, to help assess whether coeliac disease could be a concern. Suits people with symptoms such as bloating or fatigue who still eat gluten.
Mid-priced coeliac check, cheaper than most rivals
This blood test measures tTg-IgA, the antibody most often used to investigate coeliac disease, to help you decide whether further testing is worthwhile. It suits adults eating a normal, gluten-containing diet who want a first coeliac check.
Cheapest coeliac screen in the comparison group
A rapid at-home finger-prick blood test for tTG-IgA antibodies, a marker commonly used to help assess whether ongoing gluten-related symptoms warrant further investigation.
One of the cheapest coeliac screening tests we compare
A blood test that measures tissue transglutaminase antibodies (tTG), used to screen for coeliac disease, an autoimmune reaction to gluten. It suits people with digestive symptoms who want an initial screen before seeing a GP.
Most biomarkers in its group, but the priciest by far
A blood test combining genetic risk scores and autoantibody screening for both Type 1 diabetes and coeliac disease, for anyone wanting to check both conditions together.
Fastest Better2Know coeliac screen, priced above most peers
Screens for coeliac disease and gluten sensitivity from a single blood marker, with results back in two working days. Suits people who want a faster result than Better2Know's other coeliac screens.
Nearly triple the median price for one coeliac marker
Tests for a coeliac disease marker from a blood sample. Despite the name, Better2Know's own description discusses tissue transglutaminase (TTA) antibody testing rather than a distinct genetic method.
Most expensive test in its coeliac comparison group
A single-marker blood screen for coeliac disease from Better2Know, with results in around 10 working days. Suits people who want a basic check without paying for a wider panel.
