Comprehensive blood test to detect celiac disease and gluten sensitivity.
This blood test measures Gliadin and Transglutaminase antibodies to diagnose celiac disease, a lifelong autoimmune disorder triggered by gluten. It helps determine if you have an adverse reaction to gluten, enabling informed dietary choices and management of symptoms. Early detection is crucial for preventing long-term health complications associated with celiac disease. The test is suitable for individuals experiencing digestive issues or those with a family history of celiac disease.
