Hi,

I have tried 3 Freestyle 2 sensors today. I'm on my fourth now, waiting for the 60minute window to try again

When I scan, it says Change sensor!

All of them have a date until 2025.

I also reloaded the app.

I have tried 2 sensors on my iPhone App and 1 on the Abbott machine and both give the same message.

Any help appreciated

Thanks

Paul
 
Call Abbott. They should replace them all free of charge
 
Welcome to the forum @DotofSad .
i’ve had the odd sensor fail soon after starting or not even started. As @MrsA says ring Abbott, they will ask various details and may ask for you to return the faulty ones. They will supply return envelopes with the replacement sensors.

If you get a "rescan in 10 minutes."
It sounds to me like rapidly changing interpretation of BG levels?
That will cause the reader to hold off till it chops better sense into what's happening..

Abbott advise to ALWAYS check highs and lows with a finger prick before treating unless you feel obviously hypo.
There are limitations with all CGMs which are important to understand.
For example, a night time low could be a compression low.

the nice lady at abbott said if you get 2 hours of rescan in ten minutes it should be reported as faulty, the sensor failed the following morning
