I am curious if anyone has a good sense of how well expired sensors work, and what their effective duration truly is. I don’t mean how many days they can function when used but how many months past their due date they can be used with good expectations.
What I know:
Many of us routinely use sensors that have been expired for a few months
Dexcom does not replace expired sensors that malfunction, but rarely asks.
Does anyone have a sense of when they truly become unreliable, and how? My sense is that it must be a progressive deterioration, where noise and signal loss appear progressively earlier.
I expect that there are numerous anecdotal stories of a really old sensor working well. More statistical understanding of the aging process would be useful.
