What's this test for?

This test is ideal if you're experiencing digestive discomfort like bloating, diarrhea, stomach pain, or unexplained fatigue after eating bread, pasta, or other gluten-containing foods. It helps identify if your body is producing antibodies against gliadin, a protein in gluten, which could indicate celiac disease or gluten sensitivity. Many people use this test when they suspect gluten is causing their symptoms 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, whether to eliminate gluten completely, or if 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 implementing a gluten-free diet to see if levels improve.

What's included in this test?

This test measures Gliadin (Deamidated) Ab (IgA) and Gliadin (Deamidated) Ab (IgG). This test evaluates your immune response to gluten by measuring both IgA and IgG antibodies against deamidated gliadin peptides. These specific antibodies are highly accurate for detecting celiac disease and gluten-related immune reactions. The dual antibody approach provides a comprehensive assessment because some people may only produce one type of antibody, ensuring we don't miss a potential gluten sensitivity issue.

How should I prepare for this test?

It's important to continue eating gluten-containing foods regularly before this test, as avoiding gluten can lead to false negative results. You should be consuming gluten daily for at least several weeks prior to testing. No fasting is required, and you can take your normal medications. If you've already started a gluten-free diet, consult with a healthcare provider about the best timing for this test.

Who should consider getting this test?

This test is ideal for anyone experiencing digestive issues like bloating, gas, diarrhea, or constipation that seem related to eating bread or pasta. It's also important for people with unexplained fatigue, iron deficiency, or skin rashes who suspect gluten may be the culprit. If you have a family history of celiac disease or autoimmune conditions, this test can provide valuable screening information.

What symptoms indicate I may need this test?

Common symptoms include persistent bloating, stomach pain, diarrhea or constipation, and excessive gas after eating gluten-containing foods. You might also experience non-digestive symptoms like chronic fatigue, brain fog, headaches, joint pain, or skin rashes. Some people notice unexplained weight loss, iron deficiency, or nutrient deficiencies despite eating well, which can all be signs of gluten-related issues.

How can I manage gluten sensitivity naturally?

If you test positive for gliadin antibodies, the most effective approach is eliminating gluten from your diet by avoiding wheat, barley, rye, and contaminated oats. Focus on naturally gluten-free whole foods like vegetables, fruits, lean proteins, rice, and quinoa. Support digestive healing with bone broth, probiotic-rich foods, and anti-inflammatory foods like fatty fish and leafy greens. Give your gut time to heal, which can take several months on a strict gluten-free diet.

What is celiac disease and why does it matter?

Celiac disease is an autoimmune condition where eating gluten triggers your immune system to attack the small intestine, damaging the lining that absorbs nutrients. This can lead to malnutrition, anemia, osteoporosis, and other serious health problems if left untreated. The good news is that celiac disease is manageable with a strict gluten-free diet, which allows the intestine to heal and prevents long-term complications.

What does a positive result mean?

A positive result means your body is producing antibodies against gliadin, indicating an immune reaction to gluten. This strongly suggests celiac disease or non-celiac gluten sensitivity and means gluten is likely causing inflammation and damage in your digestive system. Your doctor may recommend additional testing like an intestinal biopsy to confirm celiac disease, but you'll likely need to adopt a gluten-free diet either way.

How often should I retest gliadin antibodies?

If you test positive and start a gluten-free diet, retesting every 6-12 months helps confirm your antibody levels are decreasing, showing the diet is working. Once levels normalize, annual testing can monitor continued compliance with your gluten-free diet. If your initial test is negative but symptoms persist, discuss retesting with your doctor in 6-12 months, especially if you have a family history of celiac disease.
