A gluten allergy test is a blood test used to look for antibodies the immune system makes after exposure to gluten, a protein found in wheat, barley, and rye. It is usually ordered when a person has symptoms such as bloating, diarrhea, rash, or fatigue after eating gluten-containing foods, or when a clinician wants to check for celiac disease or a wheat allergy.

What it measures

  • tTG-IgA — The main antibody checked for celiac disease; high levels suggest the immune system is reacting to gluten.
  • Total IgA — A control level that shows whether the IgA antibody result can be trusted.
  • DGP-IgA and DGP-IgG — Additional antibodies that can support or clarify celiac testing.
  • Wheat-specific IgE — An antibody linked to true wheat allergy rather than celiac disease.
  • EMA-IgA — A more specific celiac antibody, sometimes used to confirm a positive tTG-IgA.

Who it is for

A primary care clinician, gastroenterologist, or allergist typically orders this test. It may also be ordered for a child or adult with a family history of celiac disease or wheat allergy.

Preparation

No fasting is usually required. For accurate results, you should keep eating gluten-containing foods before the test unless your clinician tells you otherwise.

Results and what they mean

Results are reported as numbers with a reference range, and a clinician interprets them alongside your symptoms and history. A positive result does not by itself confirm a diagnosis, and a negative result does not always rule one out. This is general information, not medical advice; discuss your results with a qualified clinician.

Frequently asked questions

Do I need to stop eating gluten before this test?

No. Stopping gluten before testing can make results falsely low, so keep your normal diet unless your clinician instructs otherwise.

How long does it take to get results?

Most labs return results in about 1 to 3 business days, though timing can vary by lab and location.

Does a positive result mean I have celiac disease?

Not necessarily. A positive result shows antibodies are present, but a clinician may recommend further testing to confirm the cause.

Can this test tell the difference between celiac disease and wheat allergy?

It can help. Different antibodies point toward celiac disease or wheat allergy, and a clinician uses the pattern to guide next steps.
