Australian researchers create celiac test without gluten challenge

Australian researchers have developed a new blood test for celiac disease that eliminates the need for patients to consume gluten before diagnosis. This could significantly improve diagnosis rates. The new test, developed by WEHI and Novoviah Pharmaceuticals, involves mixing a blood sample with gluten to detect the presence of T cells associated with celiac disease, even in those on gluten-free diets. This avoids the current requirement of a "gluten challenge." Currently, many celiac cases go undiagnosed due to the unpleasant gluten challenge. The new test, expected to be available within two years, promises a more accurate and less invasive diagnostic process, potentially improving long-term health outcomes.
