Help determine if your discomfort from consuming gluten is caused by celiac disease.

Celiac disease is an autoimmune disorder caused by an immune response to gluten consumption that can lead to gastrointestinal (GI) discomfort, loose stools, weight loss, and other symptoms. If you are seeking guidance and answers because you think you may have the disease, then this screening test is for you. Our Celiac Disease Antibody Test is the first step in determining whether you may have celiac disease, providing the answers you need to take control of your health from the lab that doctors trust most.

This screening test detects and measures antibodies your body may produce as an immune response after you consume gluten, if you have celiac disease.

What's Tested

Total IgA

IgA is a class of antibody that is found throughout your body, especially in the GI tract and is involved in many of your immune responses. If your IgA levels are low or deficient, additional testing will be done to further screen your risk of celiac disease.
tTG-IgA

This is the primary screening test used to detect IgA antibodies to tTG (tissue transglutaminase).
tTG-IgG

This test detects IgG antibodies to tTG (tissue transglutaminase) and will be performed only if your IgA level is low or deficient.
DGP-IgG

This test measures IgG antibodies to DGP (deamidated gliadin peptide) and will be performed only if your IgA level is low or deficient.

Need to know for sure?

Our Celiac Disease Antibody Test follows American College of Gastroenterology guidelines by measuring tTG-IgA and total IgA.

Our Celiac Disease Antibody Test follows American College of Gastroenterology guidelines by measuring tTG-IgA and total IgA.

If necessary, a second test will be performed to measure tTG-IgG and DGP-IgG.¹

Does it run in your family?

First-degree relatives of people with celiac disease (parents, siblings or children) have a 10% risk compared to only 1% in the general population.²

Silent symptoms?

Some people do not experience any obvious symptoms related to celiac disease, but nevertheless undergo an immune response that causes damage to the small intestine (villous atrophy).³

FAQs

Celiac disease is an autoimmune disease in which the ingestion of gluten leads to damage in the small intestine. When people with celiac disease eat gluten (a protein found in wheat, rye and barley), their body mounts an immune response that attacks and damages the small intestine, causing nutrients to not be absorbed properly into the body. Celiac disease is hereditary; people with a particular genetic makeup are susceptible to developing celiac disease at any age.⁴·⁵
Celiac disease affects people differently with a wide variety of potential symptoms. People may experience digestive symptoms or symptoms in other parts of the body. The most common symptoms include abdominal pain, bloating and gas, constipation, diarrhea, fatigue, headaches or migraines, iron-deficiency anemia and weight loss. However, some may experience no symptoms at all but are nonetheless at risk if they remain undiagnosed and untreated.⁶

Find out if you have an increased risk for celiac disease with the Celiac Disease Foundation’s symptoms assessment tool.
Adults concerned they may have celiac disease, first-degree relatives of people with celiac disease and individuals with an associated autoimmune disorder or other condition, especially Type 1 diabetes mellitus, autoimmune thyroid disease, autoimmune liver disease, Down syndrome, Turner syndrome, Williams syndrome and selective immunoglobulin A (IgA) deficiency should be tested for celiac disease.⁴
This Celiac Disease Antibody Test is the first step in screening for celiac disease. Our test screens for celiac disease by measuring your antibody levels. If your results suggest celiac disease is possible or likely, talk to your healthcare provider who may consider further testing in order to diagnosis celiac disease with a small bowel biopsy.
If your results suggest celiac disease is possible or likely, you should share your results and any symptoms you are having with your healthcare provider. Your healthcare provider can determine if additional testing is necessary and discuss next steps on how to improve your health and wellness.

If your initial results indicate celiac disease is unlikely but you have a first-degree relative with celiac disease, it is reasonable to repeat this celiac antibody test in 4-5 years because celiac disease can develop at any age in people who are genetically susceptible.⁹
