Participants in the ASK program who test positive for islet autoantibodies and are having abnormal blood glucose testing are invited to participate in the TESS intervention study.


The Early Start Study (TESS) is an intervention study — conducted by the Barbara Davis Center for Diabetes at the University of Colorado Anschutz Medical Campus — to determine the best education and monitoring strategy for children/youth (ages 2-20 years) with pre-symptomatic type 1 diabetes (T1D).


The TESS study uses continuous glucose monitor (CGM) technology and staged education with a diabetes specialty team to teach families about changes in blood sugars in the lead up to symptomatic T1D. This will also allow careful monitoring and recognition of the need for insulin. The overall goal is to maintain blood sugars in target range and reduce the risk of life-threatening DKA at diagnosis.
