There are multiple CGMs that are FDA approved. However, there are few studies looking at the variability of measurements between the left and right arm, and none looking at this effect in diabetic patients. This study may identify if glucose differences exist in the left and right arm in patients with Type 1 or Type 2 Diabetes. Furthermore, it may point to future directions for research to standardize methods of glucose measurement such as consistently measuring on only one side of the body.
The goal of this clinical trial is to determine the time-matched difference in glucose levels between the left arm and right arm in patients with Type 1 or Type 2 diabetes. The main objective aims to answer: • Is there a difference in time-matched controlled glucose monitoring (CGM) - derived blood glucose between left and right arm in patients with Type 1 or Type 2 diabetes in target range (\<70 mg/dL; 70-180 mg/dL; \>180 mg/dL)? Participants will wear two Freestyle Libre 3 sensors, 1 on the left and 1 on the right arm, continuously for 2 weeks. Participants will need to download the Freestyle Libre 3 app on two separate mobile devices and connect the sensors with Freestyle Libre View accounts provided by the study team. The study team will collect and compare the data between the left and right arm for further analysis.

Freestyle Libre 3 consists of a sensor that is applied to the back of the upper arm. The sensor is a penny-sized flexible filament placed beneath the skin surface to measure interstitial fluid. This sensor is applied utilizing a sensor applicator provided in the packaging. The sensor will continuously read interstitial glucose readings every minute and syncs with the Freestyle View app. At the completion of the study, the sensor is discarded per protocol.

RECRUITINGTime-matched CGM-derived blood glucose differences between left arm and right arm in patients with Type 1 or Type 2 Diabetes below target range (<70 mg/dL).
Data gathered from the CGM device will be sync'd with the Freestyle View app and made available to the study team for analysis below the target range (\<70 mg/dL).
Time frame: 14 days
Time-matched CGM-derived blood glucose differences between left arm and right arm in patients in target range (70-180 mg/dL).
Data gathered from the CGM device will be sync'd with the Freestyle View app and made available to the study team for analysis at the target range (70-180 mg/dL).
Time frame: 14 days
Time-matched CGM-derived blood glucose differences between left arm and right arm in patients above target range (>180 mg/dL).
Data gathered from the CGM device will be sync'd with the Freestyle View app and made available to the study team for analysis at the target range (\>180180 mg/dL).
Time frame: 14 days
