No Alternative Site Testing
Do not use alternative blood glucose site testing (blood from your palm or
forearm, etc.) for calibration. Alternative site blood glucose values may be
different than those taken from a fingerstick blood glucose value and may not
represent the timeliest blood glucose value. Use a blood glucose value taken only
from a fingerstick for calibration. Using alternative site blood glucose values for
calibration might affect the Dexcom G5's accuracy.
When Not To Calibrate
Do not calibrate if your blood glucose is changing at a significant rate, typically
more than 2 mg/dL per minute. Do not calibrate when your receiver screen is
showing the rising or falling single arrow or double arrow, which indicates that
your blood glucose is rapidly rising or falling. Calibrating during rapid rise or fall
of blood glucose may affect sensor accuracy.
Don't Share Your Transmitter
Do not share your transmitter with another person or use a transmitter from
another person. The Dexcom G5 is a prescription-only medical device and is
meant, or indicated, for individual use only.
The transmitter is tied to the sensor glucose readings. If the transmitter is used
by more than one person, the glucose readings, alerts, and reports may be
wrong.
Caution
U.S. law restricts the sale of the Dexcom G5 to sale by or on order of a physician.
