Home use of the FreeStyle Navigator™ continuous glucose monitoring system over 5 days: Clinical evaluation in patients with type 1 and type 2 diabetes

Introduction: The FreeStyle Navigator™ Continuous Glucose Monitoring system is based on enzymatic amperometric glucose detection in the subcutaneous tissue. Using the Wired Enzyme™ technology, interstitial fluid (ISF) glucose is continuously converted into an electrical signal and, after calibration, displayed as glucose values in real-time. Aims: Originally each FreeStyle Navigator sensor was designed to be used over 3 days and then to be replaced. The goal of this study is to evaluate the accuracy and reliability of the FreeStyle Navigator over a time period of 5 days wear per sensor with consecutive sensors w…
