Freestyle Libre 3 sensor alert
Abbott, maker of Freestyle Libre, is notifying people who use the Libre 3 that three lots of sensors may be giving false high blood sugar readings. Of course we all know the danger of thinking you’re high when you’re not, injecting insulin and finding you’ve just induced a bad hypo.
The three lot numbers are:
You can find the lot number on the bottom of your sensor box as pictured above. It’s written in white on black background. If you no longer have the box you can find the lot number in the Freestyle Libre app.
Abbott says the issue affects only a small amount of sensors but if your sensor is in one of these three lot numbers visit the site and select “CONFIRM SENSOR SERIAL NUMBER.”
