Deamidated Gliadin Antibody (IgG, IgA)
Antibodies that help detect celiac disease, especially when standard gliadin testing falls short.
Consider this test if:
- Chronic diarrhea, bloating, abdominal pain, or unexplained weight loss
- Iron deficiency, fatigue, or other findings that point toward malabsorption
- A first-degree relative has celiac disease and you want to be screened
- Known or suspected IgA deficiency, where IgA-based celiac tests can read falsely normal
- Following up a borderline or positive tTG result before considering a biopsy
- HSA/FSA eligible
- Results delivered to your dashboard · Reviewed by a real clinician
- Drawn at a CLIA/CAP-accredited lab near you ·
Pre-test considerations
No fasting required. Stay on a normal gluten-containing diet before testing, since cutting out gluten lowers these antibodies and can produce a falsely normal result. If you have already started a gluten-free diet, tell your clinician, as testing may need to be reconsidered.

What this test is for
Deamidated gliadin peptide (DGP) antibodies are immune antibodies directed at gliadin, one of the main protein fractions of gluten, after it has been chemically modified (deamidated) in a way that matches the targets seen in celiac disease. This test measures both the IgG and IgA classes, which makes it useful when investigating chronic diarrhea, bloating, weight loss, iron deficiency, fatigue, or a family history of celiac disease, and when IgA deficiency would make IgA-only testing unreliable. Older anti-gliadin assays also turned positive in people without celiac disease, so DGP assays were designed around celiac-specific epitopes and are far more accurate. It is typically interpreted alongside tissue transglutaminase (tTG) IgA, which remains the primary screening antibody for celiac disease.
This is the combined IgG and IgA version. The separate IgG-only form is used mainly when total IgA is low or deficient and the IgA result cannot be trusted.

Frequently asked questions
View all FAQsHow does pricing work?
Every test shows the member price next to the standard non-member price, so you can see what membership saves you. The member price is our cost, covering the lab and what it takes to run the service. It is never a profit on the test itself. Mito makes its money on the $9 membership, not on marking up your tests. Membership is $9 per month, and any applicable lab order or draw fee is itemized before you pay.
Where do I get tested?
Choose an available partner lab at checkout. If your cart contains multiple blood tests, Mito helps consolidate the eligible tests at one lab when possible. At-home kits and scans follow the collection or appointment process shown on their product page.
Is this eligible for HSA/FSA?
Yes. Eligible tests can be paid for with an HSA or FSA card at checkout.
When will I get my results?
Your results appear in your Mito dashboard after the laboratory completes processing. A clinician then reviews them before your analysis and personalized action plan are finalized. Timing varies by test, and specialty assays and at-home kits may take longer.
Do I need a physician's order?
No. Mito provides the laboratory order when one is required, so you do not need to arrange a separate physician visit before purchasing.
