Celiac Disease Panel (Including HLA typing)
No reviews yet
Comprehensive Celiac Disease Diagnostic and Genetic Screening Panel.
This lab panel is an effective screening tool for celiac disease because it measures key antibodies (tTG and gliadin) that indicate an immune response to gluten, a hallmark of the condition. It also includes a test for IgA deficiency, which can affect the accuracy of other tests. Additionally, HLA typing identifies genetic markers (HLA-DQ2 and HLA-DQ8) associated with a higher risk of celiac disease, helping assess genetic susceptibility.
Why We Love This
This panel is a must-have for anyone concerned about celiac disease. By testing key antibodies and IgA levels, it ensures accurate results while uncovering insights into gluten sensitivity and gut health.

What to Expect
Panel is drawn at Quest Labs. Locations are available nationwide.
Important note: If you have been gluten free, you will want to consume gluten for 3 weeks (at least 4 servings per week), leading up to testing. While this does not affect genetic results, it does influence antibody results.
