PRECISION Study: Evaluating the Accuracy of the LabPatch Continuous Glucose Monitor

Completed

Conditions studied: Type1 Diabetes Mellitus, Type 2 Diabetes Mellitus

In brief

The purpose of this study is to evaluate the accuracy and efficacy of the Cambridge Medical Technologies, LLC LabPatch Continuous Glucose Monitoring (CGM) System compared to a laboratory glucose analyzer (YSI 2300 STAT Plus) and 2 commercial glucometers, OneTouch Verio and Freestyle Lite. The LabPatch system includes: 1. The LabPatch circuit chip which lies in the center of a circular push-button. The circuit is in the form of a small chip (approximately 15.7 mm \[0.618"\] x 15.7 mm \[0.618"\]) placed in contact with the skin. The chip has a telescopic micropipette which draws interstitial fluid to be analyzed for glucose levels. The chip is also able to measure skin temperature to ensure appropriate skin contact. 2. A Lab Patch holding device (blue box). 3. A wire that connects the chip to a laptop that continuously captures glucose data.
