Blood Glucose Differences Using CGMs Between the Left and Right Arm in Patients With Diabetes

Status unconfirmed · Not applicable

Conditions studied: Type 1 Diabetes, Type 2 Diabetes

In brief

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.
