Three Sensors on My Arm, Three Different Numbers — Here's Why
I wore a Dexcom G7, a FreeStyle Libre 3 Plus, and a Medtronic Simplera at the same time — and they almost never showed the same number. Here's why the differences are normal, what a rigorous independent study found, and why you can still trust the sensor you wear.
