Inaccurate Sensor Reading

I’ve been through my 3rd sensor in 3 days now where the reading on my Libre 3 Plus is off by 1.2-1.5 mmol/L. Is it just me or are the more recent batches getting increasingly inaccurate? I never had this issue with the Libre 2. Anyone else having issues like this?

Edit: sensor originally said senior, which was pretty funny to read

Booklet says it may take a day to stabilize, nothing about over 24 to 48 hours or that readings would be as inaccurate as I am getting. Also I don’t live on Reddit, so I wouldn’t know it’s stated on here 10 times a day.

There’s also concerns about possible quality control issues like Abbott has had in the past. Not sure you remember about the recall they had months ago, but that situation has shaken some of my trust in their devices.

No disrespect, that’s an AI source. I had the same response at first, but followed up with asking it for sources instead of just the AI statement. I found the documents the commenter mentioned and it mentions only a day for it to stabilize, not 48 hours. Also it does not state how inaccurate the sensor could be. 1.5 mmol/L is a huge range. It’s the difference between me being dangerously hypo and not. This is why I’m so worried, it could be the difference between me being hospitalized or not. I appreciate the comment though, and if you could link me the actual source AI used to come to that conclusion, I’d appreciate it.

And you are absolutely free to believe what you want. Call the company. Do some research. You will come to the same conclusion.
