Gluten tests: USA, Australia, NZ

The information on this page might have been superseded by changes made by individual medical laboratories. New gluten-disorder tests are likely to be developed over the net few years. This includes the Cyrex laboratories.

Gluten tests: USA, Australia, NZ


The following medical laboratories in the USA have measured IgG-gliadin (using Inova Diagnostic gliadin IgG kits).

  • Duke University
  • Thomas Jefferson Univ. Hospital
  • Alverno Clinical Laboratories
  • University of Washington
  • The Miriam Hospital
  • Clinical Pathology Laboratories
  • Allergy A.R.T,S,
  • Quest Diagnostics, MA
  • Meridian Valley Clinical Lab

LabCorp also offered this test but as part of an overall IBS test panel.

Please ask your doctor to send you to one of these labs for the gliadin test – but check it out first in case this has changed.


For people living in Sydney, Australia. Information about getting IgG-Gliadin blood tests in Sydney.
First, why the difficulty? There are 3 things to understand about the blood-test confusion that we find ourselves in:

  • Most doctors (GPs and specialists) only look for celiac disease. The best blood tests for celiac disease are the tTG and the new test and DGP (deamidated gliadin peptide) which are excellent tests to diagnose the gut damage of coeliac disease.
  • The test for gluten, IgG-Gliadin antibody, is excellent for finding out about gluten reactions. However, this gluten test has been abandoned by most Australian labs (because it does not give any indication of gut damage). The immunologists still need to be persuaded that the entity of gluten-sensitivity exists. They remain “institutionally blind” because their focus is on celiac disease rather than helping people with symptoms.
  • Now the confusing bit! The brand new DGP test (which measures the immune system’s reaction to a tiny fraction of gluten – the Deamidated part) is now being called a “Gliadin test”. But this new DGP test is very different to the old Gliadin test! The labs are currently reporting both tests as “gliadin” tests. Everyone is confused.

To find a solution to the problem, I have contacted many laboratories in Sydney. However, there is more work to do.

As far as I can tell, there are only a few laboratories in Sydney that will do the old IgG-gliadin antibody test. This will have already changed:

1 – Viral Diagnostics, 9a Avon Rd, N Ryde, phone: 9888 3444

This is the medical laboratory that can do the IgG-gliadin antibody tests.

Viral Diagnostics will accept blood samples sent to it from any other laboratories.

This is the process: Ask your doctor to write on the blood form in big writing: PLEASE FORWARD THE SERUM SAMPLE ON TO VIRAL DIAGNOSTICS FOR TESTING IgG-GLIADIN AND IgA-GLIADIN ANYBODY LEVELS

2 – SDS Pathology (which is now part of the same organization as Laverty but not yet merged) Contact: Lucinda Wallman, Head of Immunology, Phone: 0410-327-562
( This lab will do the IgG-gliadin antibody test, but this may be abandoned soon.

3- Hanly Moir Pathology might do this – but you have to ask – I have been given differing info on this (it might depend on the location)

4 – Analytical Reference Labs (Victoria)
I have not got any information from them – can anyone help me here?

5 – St John of God Geelong (Victoria) will do the IgG-gliadin antibody test on request

Please can you give me more help on this?

If you know the names of other laboratories that will do this IgG-gliadin antibody test, please would you email us.

Each year the information changes, at present there is a reluctance of labs to do this gliadin test.

New Zealand

Because of persistent medical scepticism about the gluten-sensitivity diagnosis, and because this gluten test does not diagnose celiac disease, the gliadin antibody test is not offered in Auckland (by Labtests Auckland). This is very frustrating for everyone.

However, many other gastroenterologists and allergist, worldwide, also rely on this IgG-gliadin test as a marker of gluten-sensitivity.

You can send blood sample to Christchurch, NZ

However, Labtests Auckland Ltd (and previously Auckland Diagnostic Medlab) when asked, might courier your blood sample down to Canterbury Health Laboratories for testing (they might charge about $70 for this service). You must very clearly identify the IgG-gliadin request on your blood form.

See your GP
To get this test, you need your own GP to fill out your blood form. Ask for these tests for comprehensive testing for celiac and gluten problems:

Use the eClinic for help with the interpretation.

Because the Auckland GPs are unfamiliar with the gliadin test (it is not offered in Auckland), they subsequently are unsure of the interpretation. So if you enter the blood test results into the “TEST results” section of the eClinic, you will get an accurate interpretation.

The reasons for many laboratories to abandon the gluten tests are as follows:
1) Most Medical Practitioners are currently only looking for celiac disease.

2) Currently, there are 3 blood tests available for identifying celiac disease. These are: the tTG, the DGP and the EMA tests. Different labs do different tests – there is no standard approach.

3) Most Medical Practitioners have been trained to disregard IgG-gliadin results in the diagnosis of celiac disease.

4) The diagnosis of gluten-sensitivity is often regarded by some medical practitioners with scepticism, because the concept of the gluten syndrome is very recent.
