Gliadin Antibody testing is ordered to aid in the diagnosis of Celiac Disease or other conditions related to gluten sensitivity such as Dermatitis Herpetiformis. This test looks for two types of antibodies which develop in people who have Celiac Disease in response to Gliadin, a component of products which contain gluten. The Gliadin Antibody Profile looks for Deamidated Gliadin Antibody, IgA and Deamidated Gliadin Antibody, IgG. A Gliadin Atibody Profile can be ordered as a follow up to Tissue Transglutaminase Antibody testing to help determine if a person is suffering from Celiac Disease or some other form of gluten sensitivity. Gliadin antibodies tend to decrease rapidly in response to treatment for Celiac, so this test is also used to determine if treatment has been effective. Not all people with Celiac Disease have detectable levels of Gliadin antibodies. Several other types of gastrointestinal disorders may cause the presence of Gliadin antibodies Because of this, Gliadin Testing by itself may not be a able to conclusively determine the presence of Celiac Diseae.
Celiac testing is advisable for people who are experiencing symptoms associated with Celiac Disease or are aware of family members who have been diagnosed with Celiac Disease.
Gliadin testing can be ordered as a screening for Celiac disease but is more effective as a followup to other types of Celiac blood test like a Tissue Transglutaminase (tTG) IgA & IgG. People who have detectable levels of Gliadin Antibodies often order this test after treatment to see if Gliadin antibody levels have dropped. When a person is experiencing symptoms, but Gliadin and tTG antibody tests do not indicate the presence of Celiac disease, a Gluten Allergy IgE test is often ordered.
A final diagnosis for Celiac Disease should be confirmed b a doctor and may require an intestinal biopsy. For more information on Celiac Disease testing, pleae visit the Celiac Disease Foundation at www.celiac.org.
Turnaround time for the Gliadin Antibody Profile is typically 1-3 business days.
This celiac disease test has no fasting requirements. Please note it is recommended that prior to taking the gliadin antibody test, a regular diet including items that contain gluten should be followed for 2 weeks as a gluten-free diet may not provide an accurate representation of potential gluten sensitivity.More Celiac Test & Disease Info
