09 Aug 2019 --- Distinct markers in the blood of people with celiac disease have been detected within a few hours of gluten being consumed, according to new research by specialists in the field. The new findings point to a potential technique for a more efficacious method of diagnosing the disease. The potential blood-based test would be a vast improvement on the current approach, which requires people to consume gluten for a number of weeks, and even months, for the testing to be accurate, note the researchers.
