The Gliadin Deamidated Peptide IgG Antibody Test detects IgG antibodies to deamidated gliadin peptides, helping diagnose celiac disease in patients with IgA deficiency or gluten-related disorders. Elevated levels indicate an autoimmune response to gluten that may damage the small intestine. Doctors use this blood test to evaluate persistent digestive symptoms, confirm celiac disease, or monitor dietary compliance with a gluten-free diet for improved health outcomes.

The Gliadin Deamidated Peptide IgG IgA Antibodies Test detects both IgG and IgA antibodies against deamidated gliadin peptides, highly specific markers for celiac disease. Elevated results indicate an autoimmune reaction to gluten that can damage the small intestine. Doctors use this test to confirm suspected celiac disease, evaluate unexplained digestive issues, or monitor compliance with a gluten-free diet, often alongside tTG and other celiac antibody tests.

The Endomysial IgA Antibody Screen with Reflex to Titer Test measures IgA antibodies linked to celiac disease and gluten sensitivity. It supports evaluation of chronic diarrhea, abdominal pain, weight loss, or nutrient deficiencies tied to autoimmune activity. Reflex to titer enhances diagnostic clarity, providing valuable information about intestinal damage, immune health, and systemic conditions.

The Tissue Transglutaminase (tTG) IgG Antibody Test helps diagnose celiac disease in patients with IgA deficiency by detecting IgG antibodies against tissue transglutaminase. Elevated levels suggest an autoimmune reaction to gluten that damages the small intestine, leading to malabsorption, diarrhea, or anemia. Doctors order this test to confirm gluten intolerance, support diagnosis of celiac disease, and monitor adherence to a gluten-free diet.

The HLA (Human Leukocyte Antigen) Typing for Celiac Disease test is a genetic test that identifies specific HLA gene variants associated with an increased risk of developing celiac disease. Celiac disease is an autoimmune disorder triggered by the ingestion of gluten, a protein found in wheat, barley, and rye. This test aids in assessing the genetic predisposition to celiac disease.

The Tissue Transglutaminase (tTG) IgA Antibody Test screens for celiac disease by detecting IgA antibodies against tissue transglutaminase, a marker of gluten intolerance. Elevated levels suggest an autoimmune reaction that damages the small intestine. Doctors order this test for patients with chronic diarrhea, bloating, weight loss, or anemia. Results provide critical insight for diagnosing celiac disease and guiding gluten-free diet management.
