Some Tips for Maintaining the Accuracy of Your Child’s CGM System

Maintaining the accuracy of your child’s Continuous Glucose Monitoring (CGM) system is crucial for effective diabetes management. Here are some helpful tips:

  1. Calibration Matters:
    • Take CGM calibration seriously:
      • Always wash your hands before performing a fingerstick calibration.
      • If handwashing isn’t possible, wipe away the first drop of blood and use the second drop for calibration.
      • Dirty hands can lead to inaccurate blood glucose (BG) meter readings, affecting CGM calibration.
    • Avoid calibrating when glucose levels are low or rapidly changing. Optimal times are in the morning or right before bedtime when hands are clean and glucose tends to be stable.
  2. Day One Accuracy:
    • Understand that CGMs tend to be less accurate on the first day, especially in the hours after sensor insertion.
    • Be patient during this initial period and exercise caution, especially for insulin dosing.
    • Some people find that delaying the official sensor warm-up by a few hours (while wearing a new sensor) improves day one accuracy.
  3. Monitor Trends, Not Perfection:
    • View CGM values and alarms as a helpful speedometer for diabetes management.
    • Don’t expect perfection; instead, focus on trends and patterns.
    • Use the data to make informed decisions about insulin dosing, meal planning, and physical activity.
  4. Sensor Insertion and Adhesive:
    • Insert the sensor properly to ensure accurate readings.
    • Pay attention to adhesive quality to prevent sensor displacement.
    • Some users find applying an over-the-counter adhesive product (like Skin Tac) helps keep the sensor in place.

As we know the individual experiences with CGM accuracy may vary child to child. Regularly consult with your child’s healthcare provider to fine-tune CGM settings and address any concerns.
