053 - Celiac Disease Evaluation (4 tests)

Celiac Disease Evaluation (TTG-A, DGP-A, TTG-G, DGP-G)

The Celiac Disease Evaluation is a blood test that includes four antibody tests used to assess immune responses associated with celiac disease. These tests help identify antibodies produced in reaction to gluten exposure, which can damage the small intestine in individuals with celiac disease. This panel is commonly ordered when symptoms such as chronic diarrhea, bloating, abdominal pain, fatigue, unexplained anemia, or nutrient deficiencies are present, or when there is a family history of celiac disease. Results can help support diagnosis and guide further evaluation when gluten-related disorders are suspected. The panel includes 4 tests: tTG-IgA (Tissue Transglutaminase Antibody, IgA): Primary screening test for celiac disease DGP-IgA (Deamidated Gliadin Peptide Antibody, IgA): Helps detect immune response to gluten tTG-IgG (Tissue Transglutaminase Antibody, IgG): Useful when IgA deficiency is present DGP-IgG (Deamidated Gliadin Peptide Antibody, IgG): Supports detection of celiac disease in IgA-deficient individuals
