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.
4 biomarkers as listed by Selph.
The Coeliac Disease Blood Test measures four antibodies: tissue transglutaminase IgA, endomysial IgA, deamidated gliadin peptide IgG, and total IgA. Testing total IgA alongside the others matters because some people have an IgA deficiency that can make a tissue transglutaminase IgA result misleadingly low, so the panel also checks deamidated gliadin peptide IgG as a backup marker in that situation.
Against the 11 coeliac tests we track, its 4 markers are far above the median of 1, and its £63 price is 63% below the £169 median. Most competitors, such as Bluecrest Wellness (£65) and Blue Horizon Medicals (£106.25), test only the single tissue transglutaminase marker. Only Selph's own Essential IBS Test (£199) and Randox Health's Autoimmune Type 1 Diabetes and Coeliac Detection Panel (£299) match its 4-marker coverage, both at a substantially higher price.
This combination of high marker count and low relative price is why it scores at the top of the scale for Clinical Depth and value for money. Collection Convenience and Trust Signals also score highly, reflecting the choice of collection method and doctor review of every result.
This suits you if you have gut symptoms that could be linked to gluten, such as bloating, diarrhoea or stomach pain, and want a fuller antibody panel than the single-marker tests most providers offer. If you have already had a positive antibody result and want additional markers alongside inflammation and infection screening, Selph's own Essential IBS Test (£199) covers a wider mix, though at a higher price.
You can collect a sample at home with a finger-prick kit included in the price, or pay more for the Tasso EasyDraw device, a clinic visit or a nurse draw at home or work; a self-arranged venous draw is also included. A Selph doctor reviews your antibody results and provides a written report, typically within 2 to 3 days.
This 4-marker coeliac antibody panel costs £63, well below the £169 median for the 11 coeliac tests we track and far ahead on marker count, since most rivals test only one antibody. Only Selph's own Essential IBS Test (£199) and Randox Health's Autoimmune Type 1 Diabetes and Coeliac Detection Panel (£299) match its 4 markers, both at a much higher price. The main thing to bear in mind is that any antibody test needs interpreting alongside your symptoms and diet.

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.
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.
