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.
1 biomarker as listed by Check My Body Health.
This test looks for tissue transglutaminase IgA (tTG-IgA) antibodies, a marker commonly raised when the immune system is reacting to gluten in a way consistent with coeliac disease. It is a single-marker screen rather than a full antibody panel.
Among the coeliac tests we track, it is the cheapest by some margin: the next cheapest, from Selph, costs £63 for four markers, and prices in the group run up to £299 for Randox Health's four-marker panel. At £15.99, it sits far below the £169 group median.
It scores well for value for money and for collection convenience, since it is a self-read test with a result in minutes rather than a postal blood test. It scores lower for results and follow-up because, in line with the rest of the range, it is not doctor-reviewed as standard, and moderately for clinical depth since it checks one marker rather than the broader four-marker panels some competitors offer.
This suits you if you want a low-cost, immediate first check for a coeliac-related antibody, for example if you have digestive symptoms and want an initial read before deciding whether to pursue a fuller work-up. If you want more than one antibody covered, Selph's Coeliac Disease Blood Test checks four markers for £63, and Medichecks' Coeliac Blood Test checks two markers for £169, both broader panels than this single-marker self-test.
You take a finger-prick blood sample at home and read the result yourself, with the provider stating a result in around ten minutes and no need to post anything to a lab. Results are not doctor-reviewed as standard; the provider recommends speaking to a doctor about a positive result or ongoing symptoms.
This single-marker rapid test checks for tTG-IgA antibodies from a finger-prick blood sample in around ten minutes, and at £15.99 it is the cheapest coeliac test we track, well below the £169 group median. It is not doctor-reviewed as standard, so any positive result needs following up with a doctor.

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.
3-marker coeliac panel priced below the group median
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.
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.
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.
