Data was provided for evaluation. Patient entered a calibration at 04:25am utc. The calibration was not accepted as did not meet the minimum value requirement of >40 mg/dl. Patient had entered 33 mg/dl g5 mobile application responded with a displayed message prompting to enter another bg value. A calibration was successfully entered at 07:35am utc upon which the patient's g5 mobile application displayed a value and audibly gave a low alert. It is between the time of 04:25am utc and 07:35am utc that the patient alleges the adverse event took place, during this time no alert was given for the low glucose due to the g5 mobile application not displaying any values during its request for an additional calibration.
