Gluten Intolerance: Key Tests SAVE 20%

The Gluten f79 IgE Test measures IgE antibodies specific to gluten proteins in the blood. Elevated levels suggest an allergic-type immune response to gluten, which may cause symptoms such as digestive issues, skin reactions, or respiratory problems. This test helps evaluate possible gluten allergy and guide further diagnosis or management.

The Immunoglobulin E (IgE) Test measures IgE antibody levels in blood to evaluate allergic reactions, asthma, and immune response. Elevated IgE may indicate allergies to food, pollen, or other triggers, as well as eczema or parasitic infections. Doctors order this test to investigate symptoms like hives, sneezing, or wheezing and to guide allergy treatment. Results provide vital insight into immune health, allergic sensitivity, and overall diagnostic care.

The Tissue Transglutaminase IgG IgA Antibodies Test detects both IgG and IgA antibodies to tissue transglutaminase, which are commonly elevated in celiac disease. It helps screen for and diagnose celiac disease by identifying an immune response to gluten and may also be used to monitor treatment and dietary adherence.

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 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 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 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.
