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 Celiac Disease Comprehensive Panel screens for celiac disease by measuring Tissue Transglutaminase (tTG) Antibody IgA and total IgA. If tTG IgA is positive, an Endomysial Antibody Screen IgA is added for confirmation. If IgA levels are low, tTG IgG is performed to ensure accurate detection. Doctors use this blood panel to identify gluten sensitivity, confirm diagnosis, and guide treatment for patients with suspected celiac disease.
