• Do not use alternative blood glucose site testing (blood from the
palm or forearm, etc.) for calibration as alternative site readings may
be different than those from a blood glucose value. Use a blood
glucose value only from the fingers for calibration.
• Use only blood glucose values between 40-400 mg/dL for
calibration. If one or more of the values is outside of this range, the
receiver will not calibrate.
• Use the same meter you routinely use to measure the blood glucose
to calibrate. Do not switch the meter in the middle of a sensor
session. Blood glucose meter and strip accuracy vary between
blood glucose meter brands.
• Before taking a blood glucose measurement for calibration, wash
hands, make sure the glucose test strips have been stored properly
and are not expired and make sure that the meter is properly coded
(if required). Carefully apply the blood sample to the test strip
following the instructions provided with the meter or test strips.
• Make sure you are using the blood glucose meter following the
manufacturer's instructions to get accurate blood glucose values for
calibration.
• Make sure you have not taken any medications containing
acetaminophen (such as Tylenol) to ensure you are getting accurate
blood glucose values for calibration.
