Arm Intervention/treatment
Experimental: Intervention
FreeStyle Libre Flash Glucose Monitoring System
Device: FreeStyle Libre Flash Glucose Monitoring System

Subjects will wear the FreeStyle Libre Flash Glucose Monitoring System masked for 14 days.

During these 14 days subjects will be asked to perform 4 blood glucose tests (pre-meals and before bedtime) per day. At the same time as the blood glucose test a sensor scan is performed.

Primary Outcome Measures :
  1. Point Accuracy Determined as % Within Consensus Error Grid Zone A [ Time Frame: 14 days ]

    Point accuracy of Sensor based glucose values versus fingerstick blood glucose determined as % within Consensus Error Grid zone A.

    Zone A is defined as the zone of "clinical accurate measurements with no effect on clinical action."
