What is a TRU Directional Arrow™ Indicator?
The FreeStyle Navigator system provides TRU Directional Arrow™ Indicators with each glucose reading that tell you which way and how quickly your glucose levels are changing. So, at any given time, you not only know what your glucose level is currently, but also which way your glucose level is heading. There are a total of five arrows that tell you whether your glucose levels are changing gradually, changing moderately, or changing rapidly.
