 Ask the Experts 

Ask the Experts is a program for health care providers and individuals/ families living in the United States who screen positive for type 1 diabetes (T1D) associated antibodies or celiac disease. Together with our national network of clinical and research partners, we provide: (1) education and support, (2) monitoring guidance and resources, and (3) access to early treatment interventions.

We are a passionate and experienced team of physicians, scientists and clinical research managers at the Barbara Davis Center for Diabetes and Colorado Center for Celiac Disease.


We are dedicated to helping healthcare providers and families navigate the screening and follow-up process and will refer. Our experience comes from interpreting the type 1 diabetes screening results of over 30,000 children living in Colorado, of which ~3% have screened positive and been followed by our team. We have celiac disease experts on our team as early symptoms of T1D and celiac disease can overlap, and some T1D screening programs also screen for celiac disease. Our team has participated in every major type 1 diabetes screening and monitoring program that has been available for the past thirty years including DAISYTEDDY, TrialNet, ASK, and TESS.


When a screening test is positive, we partner with health care providers and families to ensure each person who tests positive receives a confirmation test and has a local expert available. The expert will provide the education and medical monitoring needed to avoid severe illness and complications at the onset of type 1 diabetes or celiac disease and discuss opportunities for early treatment which may be available through clinical research trials. If a local expert is not available, we will work to expand our expert network to someone in your location. In the meantime, we will provide support remotely through web-based resources and connect you with an expert from our team. We are committed to providing support to health care providers and families from the initial screening through the time leading up to a type 1 diabetes diagnosis.  


We look forward to partnering with you!
