7.6 Preparing for Calibration
Your sensor depends on you to help make its sensor glucose readings accurate. If you don’t
prepare properly for the calibration, your sensor may not provide you with the most accurate
sensor glucose readings.
When taking a fingerstick, it’s important to do it correctly. Make sure you wash and dry your
hands. Always use soap and water, not a gel cleaner, as gel cleaners can affect the values.
And remember; always use your fingertip, never another site.
Eight Steps to Successful Calibration:
Do:
1. Wash and dry your hands before taking a fingerstick measurement.
a. Always use soap and water, never gel cleaners.
i. Gel cleaners may affect your meter values.
2. Always use the same BG meter you routinely use to measure your BG.
a. BG meter and strip accuracy vary between meter brands.
b. Switching within a session might cause sensor glucose readings to be less
accurate.
3. Follow BG meter’s instructions exactly when taking your fingerstick measurement.
4. Verify test strips are current and, if required, coded correctly with BG meter.
5. Check: that Bluetooth is active.
6. Use fingerstick (fingertip) BG values only.
a. Other sites are not as accurate.
b. Must enter within five minutes of taking BG meter value.
c. Enter exact BG value from your meter for each calibration.
