How are Zöliakie Test and allergy related?

A celiac test (e.g., tTG-IgA) and an allergy test (e.g., IgE to foods) are not the same. Celiac disease is an autoimmune reaction to gluten that damages the small intestine, whereas a food allergy is an IgE-mediated immediate response (e.g., hives, anaphylaxis). Both can cause similar symptoms like bloating or abdominal pain, which is why they are sometimes confused. MyBody-X offers IgE allergy tests that indicate sensitization but do not confirm clinical allergy. A celiac test is performed separately (blood antibodies, possibly duodenal biopsy). The evidence for this distinction is standard medical practice. Caveat: A positive IgE test does not automatically mean allergy; a negative celiac test does not rule out non-celiac gluten sensitivity. If celiac disease or allergy is suspected, medical evaluation is essential.
