Top Questions on Calibration


Today we’ve asked Tasha, Senior Therapy Support Specialist on our StartRight team, to share her top calibration tips. With years of experience serving people with diabetes, she has experience helping many different individuals with unique needs. We hope these tips come in handy for you!

Have you ever felt like you just can’t quite figure out the appropriate time to calibrate your sensor? If so, you are not alone. In fact, calibration questions come up frequently before, during, and after training on a continuous glucose monitor (CGM). Here are some helpful tips to set you up for success when calibrating your CGM.

What does it mean to calibrate a CGM?


When is the best time to calibrate?

Calibrating a sensor is not meant to be complicated or tricky. Getting into a habit of calibrating your sensor like you brush your teeth (hopefully not just once a day) or before you sit down to eat that meal will help prevent those sometimes “bothersome” alerts.  The best times to calibrate are before meals and at bedtime.

How should I calibrate?

In closing, remember most devices need to be calibrated to work properly. Your CGM is no different. Calibrations are just check points between your meter and your sensor to avoid skewed numbers and make sure you’re getting the best performance out of the device.

For more information, reach out to your trainer or healthcare team. You can also visit our support section [2] or refer to your user guide [3]. Hope you have a perfect numbers day!
