Celiac.com 03/05/2019 - Doctors commonly suggest celiac screening for anyone with a family history of celiac disease, or of disorders such as thyroid disease, anemia of unknown cause, type I diabetes or other immune disorders or Downs syndrome. Otherwise, patients are generally screened on a case by case basis according to individual symptoms.
Blood Testing - Antibodies Point to Celiac Disease
Screening for celiac disease usually begins with a blood test.
People with celiac disease have abnormally high levels of associated antibodies, including one or more of the following: anti-gliadin, anti-endomysium and anti-tissue transglutaminase, and damage to the villi (shortening and villous flattening) in the lamina propria and crypt regions of their intestines when they ...

Celiac.com 04/16/2019 (originally published 04/24/2008) - Genetic tests for celiac disease and gluten sensitivity are readily available. Testing can be performed on either blood and mouth swab samples. Tests can be done at home and mailed to the lab for analysis.
A good testing laboratory will provide an accurate prediction of celiac disease risk, and will also provide information about the statistical risk to your children, your likelihood of developing more severe celiac disease, whether one or both of your parents had the risk gene, and for some laboratories, you may determine your risk of gluten sensitivity without celiac disease.
DQ2 & DQ8 Not the Whole Story
About 95% of celiacs carry HLA-DQ2; while about 25% carry HLA-DQ8. If any part of the high risk gene ...

Celiac.com 10/29/2025 – Welcome to your ultimate beginner’s guide to celiac disease and gluten-free living. Whether you’re newly diagnosed or just exploring the gluten-free lifestyle, this guide will help you get started with confidence.

Celiac.com 04/15/2023 - Celiac disease is a chronic autoimmune disorder that affects the small intestine, triggered by the ingestion of gluten, a protein found in wheat, barley, and rye. One often overlooked consequence of untreated and undiagnosed celiac disease is the potential for nutrient deficiencies. Due to the damage caused to the lining of the small intestine, absorption of various essential nutrients may be impaired, leading to deficiencies that can have wide-ranging health effects. In this article, we will explore the connection between celiac disease and nutrient deficiencies, focusing on several key vitamins, minerals, and other essential nutrients.
The most common nutrient deficiencies associated with celiac disease that may lead to testing for the condition include iron...
