When should I calibrate my continuous glucose monitor?

William Lee Dubois
Endocrinology Diabetes & Metabolism
Calibrate your CGM monitor when your blood sugar is steady. Or, as I like to say, calibrate in a safe harbor so your readings are accurate in rough seas.

Don’t calibrate your monitor when you are way out of your normal range or when your BG is shifting rapidly. For one thing, your test strips aren’t as good here, and for another the delays between your fingerstick, your entry, and the calibration process all add up.
