Coeliac disease affects the body’s ability to process gluten, a protein found in wheat, rye and barley. While the disease can be managed through a gluten-free diet, diagnosis is challenging. It’s thought that around 75% of coeliac disease sufferers are undiagnosed. Olga is part of a University of Technology Sydney team that has developed a breakthrough to detect coeliac disease biomarkers in saliva. With the foundational research complete, she is looking to develop a diagnostic tool that could be available at pharmacies and used to test for the disease at home.
