This test measures antibody levels to a wheat protein (gluten) in the blood serum.

This is an important diagnosis, partly because coeliac is a risk factor for gut lymphoma and avoidance of gluten is essential and partly because this should entitle you to prescriptions for gluten free products.

Just because this test is negative does not mean you are not allergic to wheat. There are many different antigens in wheat - gluten is just one of them. Other tests which could be useful include:

  • Endomysial Antibodies
  • Reticulin Antibodies

All three tests (Gliadin A/Bs, Reticulin A/Bs, Endomysial A/Bs and also Tissue Transglutaminase) have been combined into a Gluten Sensitivity Evaluation Profile. You can request the current prices as well as any one of these tests by e-mail ( )


The gliadin antibody test is performed on a blood sample.


The kit for this test includes a red speckled top blood tube, packaging materials for transporting the blood sample in the post, a self-addressed enveloped for returning the sample to the lab and a request form.


  • Make arrangements to have a blood sample taken
  • Make sure that your name, date of birth and date sample taken are correctly entered on the blood tube
  • Make sure all the necessary details are correct on the laboratory request form.
  • Post the samples in the packaging provided making sure that the laboratory request form is enclosed with the samples.
Please, note that there is an interpretation fee for my letter to your GP. See Ordering Tests for more details.
