What's this test for?

This test is ideal if you're experiencing unexplained digestive problems like bloating, diarrhea, stomach pain, or constipation. It helps identify Celiac disease and gluten sensitivity that may be causing fatigue, nutrient deficiencies, skin rashes, or unexplained weight loss. Many people use this test when they suspect gluten is affecting their health but want concrete 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 tTG antibody levels mean for your digestive health and gluten tolerance. These notes include personalized recommendations like whether you should eliminate gluten from your diet, what follow-up tests might be needed, or when to consult a gastroenterologist. You'll also get the standard lab report and can track your antibody levels over time using our trends feature, which is especially helpful if you're implementing a gluten-free diet and want to monitor improvement.

What's included in this test?

This test measures Tissue Transglutaminase (tTG) IgA antibodies. This test measures Tissue Transglutaminase (tTG) IgA antibodies, which are proteins your immune system produces when it reacts to gluten. Elevated levels strongly indicate Celiac disease, an autoimmune condition where gluten damages the small intestine and prevents proper nutrient absorption. This test is highly accurate for detecting gluten-sensitive enteropathies and the related skin condition dermatitis herpetiformis.

How should I prepare for this test?

No fasting is needed for this test, so you can eat and drink normally beforehand. However, it's important that you continue eating gluten-containing foods before testing - if you've already eliminated gluten from your diet, the test may not be accurate. If you're already gluten-free, talk to your doctor about doing a gluten challenge before testing to ensure reliable results.

Who should consider getting this test?

This test is recommended for anyone experiencing chronic digestive issues, unexplained fatigue, anemia, or skin rashes that might be gluten-related. It's especially important if you have a family history of Celiac disease, Type 1 diabetes, or other autoimmune conditions. Children with growth delays or failure to thrive should also be tested, as Celiac disease can interfere with nutrient absorption during critical developmental years.

What symptoms indicate I may need this test?

Common symptoms include chronic diarrhea or constipation, bloating, gas, abdominal pain, and unexplained weight loss. You might also experience fatigue, brain fog, headaches, joint pain, numbness or tingling, or a blistery skin rash called dermatitis herpetiformis. Some people have iron deficiency anemia or vitamin deficiencies despite eating a healthy diet, which can indicate poor nutrient absorption from undiagnosed Celiac disease.

How can I naturally support my digestive health with gluten sensitivity?

If you test positive, following a strict gluten-free diet is essential to allow your intestines to heal and prevent further damage. Focus on naturally gluten-free whole foods like fruits, vegetables, lean proteins, rice, quinoa, and potatoes. Take a high-quality multivitamin to address nutrient deficiencies common in Celiac disease, particularly iron, B vitamins, vitamin D, and calcium. Work with a dietitian who specializes in Celiac disease to ensure you're meeting all nutritional needs while avoiding hidden sources of gluten.

What is Celiac disease and why does it matter?

Celiac disease is an autoimmune disorder where eating gluten triggers your immune system to attack the lining of your small intestine. This damage prevents proper absorption of nutrients from food, leading to deficiencies, fatigue, and various health problems. Left untreated, Celiac disease can cause serious complications including osteoporosis, infertility, neurological problems, and an increased risk of certain cancers, which is why early diagnosis and treatment are so important.

What does a positive tTG antibody result mean?

A positive result means elevated levels of tTG IgA antibodies were detected, which strongly suggests Celiac disease or gluten sensitivity. This indicates your immune system is reacting to gluten and likely causing damage to your small intestine. Your doctor will typically recommend a follow-up endoscopy with intestinal biopsy to confirm the diagnosis before starting treatment, as this is considered the gold standard for diagnosing Celiac disease.

How often should I retest my tTG antibody levels?

After being diagnosed with Celiac disease and starting a gluten-free diet, retesting every 6-12 months helps confirm your antibody levels are decreasing and your intestines are healing. Once your levels normalize and remain stable, annual testing is typically sufficient to ensure you're maintaining a truly gluten-free diet. If you accidentally consume gluten or experience returning symptoms, your doctor may recommend retesting sooner to check if antibody levels have risen again.
