Since it is important to set the alert levels in a conservative fashion, the Low Glucose Alert should
be set at a value slightly higher than the value of blood glucose you want to detect, and the High Glucose
Alert should be set at a value slightly lower than the value of blood glucose you want to detect.
NOTE: Please ask your healthcare professional which low and high alert setting is best for you.
