What's this test for?

This test is ideal if you're experiencing unexplained digestive problems like bloating, diarrhea, constipation, or stomach pain after eating bread or pasta. It helps identify celiac disease, an immune reaction to gluten that can cause nutrient deficiencies, fatigue, and long-term damage to your intestines if left untreated. Many people use this test when they suspect gluten might be causing their symptoms but want medical confirmation before committing to a gluten-free diet.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining what your antibody levels and immune markers mean for your digestive health. These notes include personalized recommendations like whether you need a gluten-free diet, follow-up testing, or consultation with a gastroenterologist for further evaluation. You'll also get the standard lab report and can track your antibody levels over time using our trends feature, which is especially helpful for monitoring dietary compliance after diagnosis.

What's included in this test?

This panel measures IgA (Immunoglobulin A) and Tissue Transglutaminase (tTG) Antibody (IgA). The test evaluates your immune response to gluten and checks for antibodies that indicate celiac disease. Total IgA is measured because some people have IgA deficiency, which could affect the accuracy of other markers, while tTG antibody is the most sensitive and specific marker for diagnosing celiac disease and monitoring how well you're following a gluten-free diet.

How should I prepare for this test?

It's crucial that you continue eating gluten-containing foods regularly before this test. You should be consuming gluten daily for at least several weeks prior to testing, as avoiding gluten can cause antibody levels to drop and lead to false negative results. Do not start a gluten-free diet before getting tested, even if you suspect celiac disease, as this will interfere with accurate diagnosis.

Who should consider getting this test?

This test is important for anyone experiencing chronic digestive symptoms, unexplained weight loss, persistent fatigue, or skin rashes that might be related to gluten. It's also recommended for people with a family history of celiac disease, those with type 1 diabetes or other autoimmune conditions, and anyone who has been advised by their doctor to rule out celiac disease before starting a gluten-free diet.

What symptoms indicate I may need this test?

Common symptoms include chronic diarrhea, bloating, gas, abdominal pain, constipation, and nausea after eating gluten-containing foods. You might also experience unexplained fatigue, brain fog, joint pain, tingling in hands or feet, irregular periods, or a blistering skin rash called dermatitis herpetiformis. Some people have no digestive symptoms at all but experience anemia, bone loss, or nutritional deficiencies instead.

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 lining of your small intestine. This damages the tiny villi that absorb nutrients, leading to malnutrition, vitamin deficiencies, and various health problems. Left untreated, celiac disease can increase your risk of osteoporosis, infertility, neurological conditions, and other autoimmune diseases, but it's completely manageable with a strict gluten-free diet.

What does high tTG antibody mean?

Elevated tissue transglutaminase antibodies typically indicate that your immune system is reacting to gluten, which is a strong sign of celiac disease. High tTG levels suggest ongoing damage to your small intestine when you eat gluten-containing foods. Your doctor will likely recommend an endoscopy with intestinal biopsy to confirm the diagnosis and assess the extent of intestinal damage.

How can I naturally support my digestive health with celiac disease?

The only effective treatment for celiac disease is strictly avoiding all gluten-containing foods, including wheat, barley, and rye. Focus on naturally gluten-free whole foods like fruits, vegetables, lean meats, fish, eggs, legumes, and gluten-free grains like rice and quinoa. Work with a dietitian experienced in celiac disease to ensure you're meeting nutritional needs and avoiding hidden sources of gluten in processed foods, medications, and supplements.

How often should I retest for celiac disease?

If you're newly diagnosed and following a gluten-free diet, your doctor will typically retest your antibody levels after 6-12 months to confirm they're decreasing. Once your levels normalize, annual testing may be recommended to monitor dietary compliance and ensure the disease remains under control. If you accidentally consume gluten or experience returning symptoms, your doctor might suggest retesting sooner to check if intestinal inflammation has recurred.
