Distributor contacted dexcom on (b)(6) 2016 to report that the patient experienced continuous glucose monitoring (cgm) inaccuracies compared to blood glucose (bg) meter on (b)(6) 2016.
The sensor was inserted on (b)(6) 2016.
It was reported that on (b)(6) 2016, a day after sensor insertion, the patient was feeling very tired and ill.
The dexcom cgm indicated that his bg was 5.
4mmol/l with a 45 degree down arrow showing.
The patient then did a fingerstick and his actual bg was 2.
4mmol/l.
After rectifying his glucose, the cgm was recalibrated and the patient's father continued to double check his readings regularly over the next 48 hours with fingerstick tests.
The sensor regained accuracy after about 36 hours and then managed to last the full 7 day without further problems, however the accuracy was never quite what had come to be expected from dexcom.
