Celiac disease is a chronic autoimmune disorder that affects the small intestine. It is triggered by the ingestion of gluten. In genetically predisposed individuals, the immune system reacts abnormally to proteins found in wheat, barley, and rye, damaging the intestinal lining and impairing nutrient absorption.
The genetic predisposition test for celiac disease allows you to identify if your body has this genetic basis. A positive result does not confirm the diagnosis but indicates a higher risk and the need to follow up with other tests. A negative result practically rules out the possibility of developing the disease.
This is a valuable tool in uncertain diagnoses and often avoids the need for invasive tests such as intestinal biopsy. It is also useful for direct relatives of people with celiac disease, as genetic inheritance increases the risk.
