  • Gliadin Antibodies

About this test

Gliadin is a protein found in gluten, and testing for antibodies against it is one part of assessing a possible gluten intolerance or coeliac disease, alongside symptoms such as bloating, diarrhoea, wind or unexplained weight loss. Better2Know's own description notes that this test is often combined with a separate Tissue Transglutaminase IgA test for a more complete result, since a Gliadin result alone does not confirm coeliac disease.

Better2Know does not list a wider comparison group for this test, so there is no named rival to rank it against directly. It tests a single antibody marker, one part of a wider picture that would typically also involve the separate Tissue Transglutaminase IgA test the provider mentions.

It scores well for collection convenience, since it is a home finger-prick kit with results back within two days, or a clinic option for £135. It scores lower for results and follow-up because results are not reviewed by a doctor as standard.

Who is it for?

This suits someone with gut symptoms that could point to gluten sensitivity who wants an initial marker rather than a full coeliac panel, understanding that a single Gliadin result is only part of the picture.

Because this test is not part of a listed comparison group, there is no specific cheaper or deeper alternative from the sheet to point to, but the provider's own notes suggest pairing it with a separate Tissue Transglutaminase IgA test for a fuller result.

How it works

You take a finger-prick blood sample at home and post it to the lab, with results back within two days. A clinic appointment is also available for £135 if you would rather have the sample taken for you. The fact sheet does not show results being reviewed by a doctor as standard.

Pros & cons

Pros

  • Home finger-prick collection with results back within two days.
  • A clinic-based option is available for £135 if preferred.
  • Can be combined with a separate Tissue Transglutaminase IgA test, as the provider itself suggests, for a fuller picture.

Cons

  • Tests one marker only; the provider itself notes it is often paired with a separate Tissue Transglutaminase IgA test.
  • Doctor review of the result is not included as standard.

Results are not reviewed by a doctor as standard.
