Event Description

A high readings issue was reported with the adc device.Customer reported initially being asymptomatic and falling asleep; however, after receiving unspecified sensor scan result perceived to be high compared to readings (unspecified) on another adc meter; the customer experienced loss of consciousness and was unable to self-treat.The customer self-presented themselves at hospital but prior to that obtained a sensor scan result reading of approximately 2.5 mmol/l.At the hospital a healthcare professional (hcp) obtained unspecified readings on their hcp meter and it was reported they treated the customer with five (5) injections of glucose.No further treatment or medication was reported.There was no report of death or permanent impairment associated with this event.A sensor reading of 8.70 mmol/l was compared against a reading of 4.00 mmol/l on another adc meter and plotted on a parkes error grid which fell into the "c" zone showing the difference in values to be clinically significant.It is unknown when these readings were taken in relation to the reported event.
