Patient contacted dexcom on (b)(6) 2015 to report continuous glucose monitoring (cgm) inaccuracies compared to blood glucose (bg) meter that occurred on (b)(6) 2015.Sensor was inserted on (b)(6) 2015.Additionally, it was reported that the patient did not calibrate after experiencing inaccuracy.The dexcom g4® platinum continuous glucose monitoring system user's guide states: if the difference between your sensor glucose reading and blood glucose value is greater than 20% of the blood glucose value for sensor glucose readings > 80 mg/dl or greater than 20 points for sensor glucose readings < 80 mg/dl, wash your hands and take another blood glucose measurement.If the difference between this second blood glucose measurement and the sensor is still greater than 20% for sensor glucose readings > 80 mg/dl or greater than 20 points for sensor glucose readings < 80 mg/dl, recalibrate your sensor using the second blood glucose value.The sensor glucose reading will correct over the next 15 minutes.At the time of contact, no injury or medical intervention was reported.
