What's this test for?

This test is ideal if you're experiencing digestive issues like bloating, diarrhea, or stomach pain after eating foods containing gluten (wheat, barley, rye). It helps detect early gluten sensitivity and celiac disease, an autoimmune condition where gluten damages your small intestine. Many people use this test when they suspect gluten is causing their symptoms but want confirmation before making major dietary changes.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining what your antibody levels mean for your digestive health and gluten sensitivity. These notes include personalized recommendations like whether you should eliminate gluten from your diet, what foods to avoid, and whether you need follow-up testing or consultation with a gastroenterologist. You'll also get the standard lab report and can track your antibody levels over time using our trends feature to see how dietary changes are working.

What's included in this test?

This test measures Gliadin (Deamidated) Antibody (IgA). This test measures IgA antibodies against deamidated gliadin peptides, which are more sensitive and specific markers for detecting celiac disease and gluten sensitivity compared to older anti-gliadin tests. These antibodies indicate whether your immune system is reacting to gluten proteins in your diet, helping identify early-stage celiac disease or non-celiac gluten sensitivity that may be causing your digestive symptoms and other health issues.

Who should consider getting this test?

This test is important for anyone experiencing unexplained digestive symptoms, chronic fatigue, skin rashes, or joint pain after eating gluten-containing foods. It's also valuable for people with a family history of celiac disease, those with autoimmune conditions, or anyone who has tried eliminating gluten and felt better. If you're considering a gluten-free diet, testing before you eliminate gluten gives you the most accurate results.

What symptoms indicate I may need this test?

Common symptoms include bloating, gas, diarrhea, constipation, stomach pain, or nausea after eating bread, pasta, or other gluten-containing foods. You might also experience fatigue, headaches, brain fog, skin rashes, joint pain, or unexplained weight loss. Some people have no digestive symptoms but experience anemia, depression, or nutrient deficiencies that can be related to undiagnosed gluten sensitivity.

How can I manage my diet if I have gluten sensitivity?

Focus on naturally gluten-free whole foods like fruits, vegetables, rice, quinoa, potatoes, meat, fish, eggs, and dairy. Read labels carefully as gluten hides in many processed foods, sauces, and seasonings. Replace wheat flour with gluten-free alternatives like almond flour, coconut flour, or gluten-free oat flour for baking. Many restaurants now offer gluten-free options, but always inform staff about your sensitivity to avoid cross-contamination.

What is deamidated gliadin and why does it matter?

Deamidated gliadin is a modified form of gliadin, a protein found in gluten-containing grains. When your body digests gluten, an enzyme called tissue transglutaminase deamidates gliadin, making it more recognizable to your immune system. In people with celiac disease or gluten sensitivity, this triggers an immune response and antibody production. Testing for these specific antibodies is more accurate than older tests for detecting gluten-related disorders.

What does a positive result mean?

A positive result means your immune system is producing antibodies against deamidated gliadin, indicating you likely have celiac disease or gluten sensitivity. This suggests your body is reacting negatively to gluten and you should avoid foods containing wheat, barley, and rye. Your doctor may recommend additional testing like an endoscopy or genetic testing to confirm celiac disease and assess any intestinal damage.

What causes high anti-DGP IgA antibodies?

High antibody levels are caused by your immune system reacting to gluten proteins in your diet, which is the hallmark of celiac disease. This autoimmune response occurs when gluten triggers inflammation and damage to the lining of your small intestine. The condition has a genetic component, so it often runs in families, and can be triggered or worsened by stress, pregnancy, surgery, or viral infections in genetically predisposed individuals.

How often should I retest my antibody levels?

If you've been diagnosed with gluten sensitivity or celiac disease and started a gluten-free diet, your doctor will typically retest every 6-12 months to ensure your antibody levels are decreasing and your treatment is working. Once levels normalize, annual testing may be sufficient to monitor your condition. If you accidentally consume gluten or have ongoing symptoms despite dietary changes, your doctor may recommend more frequent testing.
