New blood test detects coeliac disease accurately

A new blood test offers a "game-changer" for coeliac disease diagnosis, eliminating the need for patients to consume gluten for testing. This advancement could significantly improve diagnosis rates. The blood test detects gluten-specific T cells, allowing for accurate diagnosis even in individuals on gluten-free diets. This contrasts with current methods requiring weeks of gluten consumption, which often deters people from seeking diagnosis. The test showed high accuracy in detecting coeliac disease, even in those with other autoimmune conditions. Researchers are now working to validate the test across diverse populations and gather real-world data.
