Enter the Blood Glucose (BG) value into the Receiver within 5 minutes of taking the BG
reading.
Do not enter a BG value taken within 2 hours after a meal.
Do not enter BG values when an up or down arrow appears next to the glucose value on
the Receiver. When an up or down arrow appears next to the glucose value, it indicates
the glucose is quickly rising or falling. The Receiver may also give you an alert that “Blood
glucose is unstable. Please recalibrate when glucose becomes stable.”
o If customer probes for more information: When glucose is increasing or
decreasing quickly, the difference between the blood glucose meter and the CGM
reading can be substantially different. The CGM reading follows behind the finger
stick BG reading. It may be behind by at least 10 minutes or more, especially
during quick or rapid glucose changes.
If there is a large gap between the BG meter reading and the Receiver reading, (30-40%
difference in readings) wash your hands and take a 2
nd
finger stick. (Reference: Andreas)
