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.
1 biomarker as listed by Bluecrest Wellness.
Coeliac disease is an autoimmune condition in which the immune system reacts to gluten and damages the small intestine. This test measures tissue transglutaminase antibodies (tTG-IgA) in the blood, which tend to rise when someone has the condition. Bluecrest's own information is clear that a positive result should be followed by referral for an endoscopy with a small-bowel biopsy, which is the definitive way to confirm coeliac disease, and that a normal tTG result does not rule it out in every case, for example if someone has an IgA deficiency. The test also cannot identify non-coeliac gluten sensitivity, since there is no laboratory marker for that condition.
Against the coeliac tests we compare it with, this one is priced well below the £169 group median: at £65, it beats Blue Horizon Medicals (£106.25), London Medical Laboratory (£124), Medichecks (£169), Better2Know (£295) and Randox Health (£299). Only Check My Body Health's self-test (£15.99) is notably cheaper, and Selph's coeliac blood test is priced similarly at £63 but covers four markers rather than one. This mix of a strong price and a single marker gives it a high value for money score alongside a middling clinical depth score for this comparison group.
It scores highly on clarity, since the listing sets out a detailed description, the biomarker, a stated turnaround and collection method. It scores lower on collection convenience, because it requires a venous blood draw at a clinic rather than a finger-prick or at-home kit, and on results and follow-up, since there is no doctor review as standard.
This could suit you if you have digestive symptoms, such as bloating, fatigue or discomfort, and want an initial screen for coeliac disease before speaking to a GP. Bluecrest's own guidance is that you should keep eating gluten before the test, since cutting it out can lower antibody levels and cause a false-negative result. If you want more markers for a similar price, Selph's Coeliac Disease Blood Test covers four for £63, close to this test's £65. If a result is abnormal, or you continue to have symptoms despite a normal result, Bluecrest's own materials point to further investigation, and we would recommend discussing this with a GP.
This is a blood test taken by venous draw at a Bluecrest venue rather than a finger-prick sample, which the provider notes is more reliable. The sample is sent to the lab to measure tTG-IgA antibody levels, with results expected in around 3 to 8 days. There is no doctor review of results as standard, and a positive result would need following up with a GP referral for further investigation.
This test measures tTG antibodies in the blood, a marker used to screen for coeliac disease. At £65 it is one of the cheapest options among the coeliac tests we compare it with, well below the £169 group median, though Selph's own coeliac blood test costs about the same and covers four markers rather than one. There is no doctor review of results as standard.

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.
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.
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.
