Summary

This completed trial tested how accurately the True Vie I3 continuous glucose monitor measures blood sugar levels in 159 adults with type 1 or type 2 diabetes. Participants wore the device while researchers compared its readings to standard lab measurements. The goal was to see if the device meets FDA accuracy standards for integrated continuous glucose monitors.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Continuous glucose monitoring device
What this could lead to
If successful, this device could provide reliable, real-time glucose readings to help people with diabetes manage their condition more easily.
What could go wrong
This is a completed device accuracy study, not a treatment trial. Even if accurate, the device does not cure diabetes or replace standard care.
