Why It’s Done
Doctors may order the Endomysial Antibody-IgA (With Dilution) – IFA Test to:
• Diagnose celiac disease, especially in individuals who present with symptoms like diarrhea, weight loss, abdominal pain, or bloating, and in cases where other tests (like tissue transglutaminase IgA) are inconclusive.
• Confirm the diagnosis of celiac disease in patients who have gastrointestinal symptoms and a family history of the condition.
• Monitor individuals on a gluten-free diet: The test can be used to assess whether someone with celiac disease is following the appropriate diet, as the antibody levels typically decrease when gluten is eliminated.
• Evaluate suspected cases of gluten intolerance or wheat sensitivity, though this is less common.
Preparation
• No special preparation is usually required for this test.
• Inform your doctor about any medications you are taking, especially if you are on a gluten-free diet or medications like immunosuppressants that may influence the results.
• The test involves a blood sample taken from a vein in your arm.
