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 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.

The Immunoglobulin A (IgA) Test measures IgA antibody levels in blood to evaluate immune system health and mucosal defense in the respiratory and digestive tracts. Low IgA may indicate immune deficiency, celiac disease, or recurrent infections, while high levels may suggest autoimmune disorders, liver disease, or chronic inflammation. Doctors use this test to assess unexplained illness or immune imbalance. Results provide key insight into antibody function and overall immunity.

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 Wheat f4 IgE Test measures IgE antibodies to proteins in wheat. Elevated levels may indicate an allergic reaction, which can cause hives, itching, swelling, digestive discomfort, respiratory issues, or in severe cases, anaphylaxis. This test helps identify wheat allergies and supports management through dietary avoidance and treatment strategies guided by healthcare providers.

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.
