Dexcom has announced that the FDA has approved its G4 Platinum continuous glucose monitor (CGM). Clinical studies report up to approximately 19% improvement in overall accuracy compared to the Seven Plus, and approximately a 30% improvement in accuracy in the hypoglycemia range. Unlike the traditional "finger-stick" blood glucose monitor, CGM provides an in-motion picture that shows not only glucose levels, but also the speed and direction in which it is moving, and alerts the user to sudden changes so they can take action. Some features of the Dexcom G4 Platinum CGM include: longest transmission range; a smaller, discrete profile; a color LCD display for easy viewing; customizable alerts with specific tones; and a "Hypo alert" setting at 55mg/dL that provides an increased level of safety. Can be worn for 7 days before changing sensors.
