Type 2 Diabetes Glucose Biomarker Study With a Continuous Glucose Monitoring System

Study Overview
=================
Brief Summary
-----------------
Current gold standard methodologies for diagnosing type 2 diabetes (T2D) or prediabetes can be unreliable and inaccurate, and require the need for multiple different tests for comparison. It is possible that a simpler and more refined method of diagnosing T2D or prediabetes involves examining the proportional-integral (PI) control system of the body's glycemic function (i.e., a model of the glucose curve). The purpose of this research is to examine how well a PI model can diagnose nondiabetic, prediabetic, or diabetic patients based on glucose data gathered from a wearable glucose monitoring device.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Glucose biomarker data from the continuous glucose monitoring device, which will be analyzed as a function of different homeostasis responses from the 3 different cohorts of individuals (i.e., i) low to moderate risk; ii) high risk, iii) very high risk). | Continuous glucose data from the FreeStyle Libre device will be collected from each individual and analyzed for differences in glucose responses (i.e., ups and downs) across the different study groups. | The device is worn for 14 days on each participant |
