About this test

This test measures gliadin antibodies in your blood, one of the markers used alongside symptoms and family history to help assess a possible gluten-related immune response. It is not on its own a diagnosis, and the provider notes it is often taken alongside a separate tissue transglutaminase IgA (tTG-IgA) test for a more complete picture.

This clinic-based version, with a venous blood sample, costs £135. The fact sheet notes a home kit version of the same test is also available for £69, which would suit you if you would rather post a sample than attend a clinic. At £135, the in-clinic version is somewhat above the typical price for gut health tests of similar depth that we track.

It scores reasonably on clinical depth for a single-marker test and well on clarity, with a full description and a stated two-day turnaround. It scores lower on collection convenience, since it needs a clinic visit or nurse booking rather than a simple postal sample, and on results and follow-up, since doctor review of your result is not confirmed as standard.

Who is it for?

This suits you if you have symptoms such as bloating, diarrhoea, wind or unexplained weight loss, or a family history of gluten intolerance or coeliac disease, and want an initial antibody check before seeing a doctor. Since the provider itself suggests pairing this with a tTG-IgA test for a fuller picture, it may not be the best choice if you want a single, standalone test.

If cost is the deciding factor, the home kit version of the same test is listed at £69, considerably less than this £135 clinic visit.

How it works

A Better2Know clinician takes a venous blood sample from you at a clinic, which is sent to the lab for analysis of gliadin antibodies. Results are typically available within two days of the sample reaching the lab, and you will be notified when they are ready, with results in your online patient area. If antibodies are detected, Better2Know can arrange a private doctor consultation, or you can take the result to your own GP.
