Adult Accuracy Study of the Enlite 3 Glucose Sensor

This study is a multi-center, randomized, in-clinic trial that aims to demonstrate the performance of the Enlite 3 Sensor over 168 hours (7 days) when inserted in the abdomen and used with the Guardian Mobile App and 640G Pump in subjects aged 14-75 years with type 1 or type 2 diabetes for at least one year. Subjects are randomized into either Group A or Group B. The groups assigned will determine when the subject will be participating in the in-clinic YSI frequent sample testing (FST). For example on Day 1: Group A begins FST 30 minutes after Enlite 3 Sensor Insertion. Group B begins FST 14 hours after Enlite 3 Sensor Insertion.
