In gluten-sensitive individuals AGA testing is a routinely used blood test for possible presence of coeliac disease, allergies or idiopathic phenomena. This test took two types of antibodies – IgA and IgG - that develop in an individual suffering from celiac diseases. In addition, test looms 90% accuracy and potentially offers positive results after the definitive diagnostic test.• This screening test can be used to find the need for biopsy in a patient.• The test is required to diagnose Dermatitis Herpetiformis. Normal IgA Levels by Age. • The test detects the presence of overall anti-gliadin antibodies (AGA) levels inside a body that attack the protein. Positive = >50 U/L. Deamidated gliadin peptide antibodies, DGP, DGP-AGA, DGP IgA and IgG . Antigliadin antibodies (AGAs) are antibodies of the IgA and IgG classes found in the serum of celiac disease patients. The measurement of AGA is done with ELISA or radioimmunoassay. A Gliadin Antibody test is an investigation for Antibody IgA, used by the doctors to aid in diagnosing celiac diseases. This will measure the level of Gliadin antibody and detect the celiac disease to monitor its treatment. The exposure to gluten allows forming Gliadin Antibody (IgA and IgG). If IgA is below detection (<1.0 mg/dL), then tTG IgG and deamidated gliadin IgG … 2-4 months: 3-47 mg/dL.

AGAs are not specific for celiac disease as they are also found in patients with other gastrointestinal diseases such as gastritis, gastroenteritis, and IBD. Gliadin IgA/IgG = 0 to 2 years = <20 EU. However, gliadin antibodies may be found in individuals without celiac disease; thus gliadin antibody assays are less specific than assays measuring antibodies to endomysium and transglutaminase. What is the relationship of gluten and anti-gliadin antibodies? What is this test? Abnormal results: An abnormal result for AGA test is written as either weakly positive or moderate to strong positive. Greater than 10 equals disease and a value of 3 is expected (mean) . Gliadin Antibody IgG 31 – High Range Normal = <11 Gliadin Antibody IgA 6 – Normal = <6 Tissue Transglutaminase IgA <3 – Normal = <5 Then last year everything was pretty much the same but Gliadin IgG 23.4 High Range, Normal = <10 Such tests measure the level of AGA relative to a standard, such as a level of 10 = point which 85% of normal population falls below. Take notes prior and after the test results. Gliadin (GAF-3X) ELISA (IgA, IgG) and the Anti-Gliadin ELISA (IgA, IgG). TTG IgA has higher sensitivity (approximately 95%). The test is performed for antibody deficiency. However, gliadin antibodies may be found in individuals without celiac disease; thus gliadin antibody assays are less specific than assays measuring antibodies to endomysium and transglutaminase. False positive results limit their use as a definitive diagnostic test. IgA Endomysial antibody (EMA): The EMA test has a specificity of almost 100%, making it the most specific test for celiac disease, although it is not as sensitive as the tTG-IgA test. Contrasting patterns of response in serum, saliva, and intestinal secretions. • The lab technician will tie the tourniquet around the upper arm and clean the skin over the vein with antiseptic.• Insert a needle in the vein and blood is sucked into the vial.• The sample is carried to the lab for ELISA (enzyme-linked immunosorbent assay).• The intensity of the color change represents the presence of gliadin antibodies in the blood. Their measurement has been used particularly as a screening test. Values are given for the child of age >2 years: Negative = < 25 U/L .
