Detailed Description

The study is to evaluate the accuracy and safety of a novel real-time CGM system among adult patients with type 1 diabetes mellitus with respect to YSI reference venous plasma sample measurements. No less than 36 patients will be enrolled. Each patient will wear two sensors. Interstitial glucose readings from each sensor will be obtained immediatedly following each venous blood sample test. Each participant will make 4 visits to the clinical study site, including the screening visit.
