Latest Practical Development of Continuous Glucose Monitoring (CGM) for Evaluating Time in Range (TIR)

During recent diabetic practice, continuous glucose monitoring (CGM) has become prevalent. The current case was a 70-year-old male with type 2 diabetes (T2D). He has used CGM for a long time and recently began using the novel FreeStyle Libre 3 system, which includes a sensor and an app for a smartphone. The benefits include painless, affordable, discreet, accurate, and real-time glucose readings at a glance. He successfully measured glucose variability for one month, which was associated with an average glucose of 148 mg/dL, a time in range (TIR) of 80%, and a time above range (TAR) of 20%. This apparatus would be convenient for beneficial clinical diabetic research.
