What's this test for?

This test is ideal if you're experiencing unexplained digestive problems like bloating, diarrhea, abdominal pain, or discomfort after eating bread and pasta. It helps identify whether your body is reacting to gluten, a protein found in wheat, barley, and rye, which could indicate celiac disease or gluten sensitivity. Many people use this test when they suspect certain foods are making them feel unwell but want concrete answers 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 and whether they suggest gluten sensitivity or celiac disease. These notes include personalized recommendations like dietary modifications, foods to avoid, or whether you should follow up with a gastroenterologist for further testing. You'll also get the standard lab report and can track your antibody levels over time using our trends feature, especially helpful if you're eliminating gluten and want to see if your levels improve.

What's included in this test?

This test measures Gliadin (Deamidated) Antibody (IgA). This test measures antibodies your immune system produces when exposed to deamidated gliadin, a form of gluten protein that's particularly accurate for diagnosing celiac disease. Unlike older gluten antibody tests, this advanced version detects specific immune responses that are much more accurate and reliable for identifying true celiac disease rather than general food sensitivities. It provides clearer answers about whether gluten is truly causing your symptoms and helps guide important dietary decisions.

How should I prepare for this test?

It's important to continue eating gluten-containing foods as you normally would before this test. Avoiding gluten before testing can lead to false negative results because your body needs to be actively producing antibodies for accurate detection. If you've already eliminated gluten from your diet, talk to your doctor about doing a gluten challenge, which typically involves eating gluten daily for several weeks before testing.

Who should consider getting this test?

This test is ideal for anyone experiencing persistent digestive symptoms like bloating, gas, diarrhea, or stomach pain, especially after eating bread, pasta, or baked goods. It's also important for people with unexplained fatigue, weight loss, or nutrient deficiencies that could be related to celiac disease. Those with a family history of celiac disease or autoimmune conditions should also consider testing even without obvious symptoms.

What symptoms indicate I may need this test?

Common symptoms include chronic diarrhea or constipation, bloating and gas after meals, abdominal pain or cramping, and unexplained weight loss. You might also experience fatigue, brain fog, headaches, or skin rashes like dermatitis herpetiformis. Some people notice nutrient deficiency symptoms like anemia or bone pain, while children may show delayed growth or behavioral changes after eating gluten-containing foods.

How can I naturally support my digestive health if I have gluten sensitivity?

The most important step is eliminating gluten completely from your diet by avoiding wheat, barley, rye, and cross-contaminated foods. Focus on naturally gluten-free whole foods like fruits, vegetables, lean meats, fish, eggs, rice, and quinoa. Support gut healing with bone broth, probiotic-rich foods like yogurt and sauerkraut, and anti-inflammatory foods like leafy greens and fatty fish. Consider digestive enzymes and work with a nutritionist to ensure you're getting adequate nutrients while avoiding gluten.

What is celiac disease and why does it matter?

Celiac disease is an autoimmune condition where eating gluten causes your immune system to attack your small intestine, damaging the lining that absorbs nutrients. Over time, this damage can lead to serious complications like malnutrition, osteoporosis, infertility, and increased risk of other autoimmune diseases. It's different from gluten intolerance because it causes actual immune system damage, which is why accurate diagnosis and strict gluten avoidance are so important for long-term health.

What does a positive Gliadin IgA antibody result mean?

A positive result means your immune system is producing antibodies against deamidated gliadin, which strongly suggests celiac disease or gluten-related immune reactivity. This indicates your body sees gluten as a threat and is mounting an immune response that may be damaging your intestinal lining. A positive result typically requires follow-up testing, including an intestinal biopsy, for definitive celiac disease diagnosis and to determine the extent of any intestinal damage.

How often should I retest my gliadin antibodies?

If you're newly diagnosed and have started a strict gluten-free diet, your doctor will typically retest in 6-12 months to confirm your antibody levels are decreasing. Once your levels normalize, annual testing helps ensure you're maintaining a truly gluten-free diet, as even small gluten exposures can cause antibodies to rise again. If you have persistent symptoms despite dietary changes, more frequent testing every 3-6 months may help identify hidden sources of gluten or assess treatment effectiveness.
