What is the Long Standing T1D study?

Most type 1 diabetes experts now believe that many patients with long standing type 1 still have the ability to produce small amounts of insulin.  Proving that patients with long standing diabetes make insulin may lead to future studies aimed at reversing diabetes.  In this study we hope to identify 10 patients with known T1D and learn if their pancreas is still producing insulin.

Who can participate?

Participants must have been diagnosed with T1D for at least 5 years, but not more than 20 years.  Participants must be 15 to 45 years of age and able to give written informed consent.

What do I have to do as a participant?

You will have screening blood tests done to determine if your pancreas is still making insulin.  If you meet screening requirements you will undergo a mixed meal tolerance test and other blood tests in the UF Clinical Research Center (CRC).  There are at most 2 study visits. You will receive $25 for completion of the screening blood draw and $50 for completion of the MMTT.
