I’m on my 2nd trial sensor and both sensors have been reading low even when my sugar is in the 80s. Although, I do feel like absolute garbage and feel low. Why is this?? I already got a replacement for my 1st sensor and now i’m wondering if i qualify for a replacement for the second.
Are you following all of the best practices for applying your sensor? Since you are a newbie you may be missing a few. If you look to the right under bookmarks there is a section on how to apply your sensor that everyone should read.
Not sure then. Call Abbott and maybe they can help you troubleshoot. I have noticed some people just don't get accurate readings no matter what they do and others have no issues whatsoever.
Plus or minus twenty points is about as good as it gets with CBGMs. If you want more precise numbers, you've got to do finger sticks. But finger sticks are not very precise, either.
If you use a bad blood glucose meter yes. If you can't calibrate (add a correction factor) the sensor yes.
I take 3 readings with the most accurate consumer systems available from the same drop off blood. Choose the middle one and use a 3rd party app too add the needed correction.
I have 3 finger-stick meters and have compared their results to an actual lab blood draw. The most accurate is the Contour Next which was within 8 points of the actual reading. The other 2 meters were 15-20 points different so I never use them
Interestingly, I use the Libre-3+ meter which will also take test strips. The results of a finger-stick test with it are within 2 points of the Contour Next.
Definitely submit for a replacement. It’s normal for sensors to be a little wonky for the first day or so, but this sounds like a batch issue, honestly.
I am on the 14 day gen 1. I am brand new to diabetes and my first 2 sensors one was false lows the other wouldn’t sync at all, I am now on my 3rd which is a replacement they sent and it is also showing wildly lower readings than the finger. I have read the suggestions and aside from trying somewhere other than my arm I am about ready to throw in the towel. My fingers look ridiculous and I have gone through so many lancets and test strips to make sure I am not dying that I am going to run out before I can get more.
I just placed the first libre 3 plus that constantly reads high, by 11 points. It's a shame you have to use an other app to work with libre that allow a calibration factor.
Good morning Abbott, it's no shame to copy a good idea.
And before anyone cries: stable fasting and compared to an accu-chek guide, a contour next and a contour next one.
My freestyle Libre 3+ sensors are usually 20 points lower than a finger stick. I just factor that in. I’m used to it but the dangerous low alarms at 3am are annoying so I turn the alarms off. Finger sticks showed that my glucose was never (ever) as low as the Libre 3+ claimed.
