The 5-Minute CGM Guide for First-Timers
What Is a CGM?
A Continuous Glucose Monitor (CGM) is a small, wearable device that tracks your glucose levels day and night. Instead of pricking your finger several times a day, a sensor sends readings straight to your phone or reader.
Top CGMs Trinity Offers:
- Dexcom G7: Accurate readings, fast alerts, and a simple app interface
 - FreeStyle Libre 3 Plus: Tiny, discreet sensor that updates regularly
 
Why So Many Patients Are Switching
- Less daily pain: No more routine finger-sticks
 - Early alerts: See highs and lows before they become serious
 - Peace of mind: View your numbers anytime, share with your care team
 - Medicare coverage: Many patients qualify depending on coverage
 
How Trinity Makes It Easy
Our Trinity CGM Care Pathway means you’re never on your own.
- Fast Insurance Check: Coverage typically verified within 48 hours
 - Free Shipping: Your CGM System usually ships within 2 business days
 - Live Onboarding: A Trinity representative walks you through setup and training
 - Ongoing Support: Our Diabetes Support Team is available for questions
 - Automatic Refills: Trinity contacts you every 90 days to confirm your refill before shipping.
 
What to Expect on Day 1
- The sensor is placed on the back of your upper arm or abdomen
 - Application is simple and comfortable
 - Sync the sensor with your phone or reader
 - Set up alerts for low or high levels (our support team can guide you)
 
Pro Tips for New Users
- Apply when your previous sensor ends. Clean, dry skin helps it stay in place.
 - Check your app daily—your glucose trends tell a bigger story than a single number
 - Keep backup snacks handy if alerts indicate a drop
 - Invite a caregiver to connect—they can receive alerts too
