Faulty Libre 2 Plus Sensors

Hi all,
I put on a new sensor yesterday (completely correctly). It failed straight away. Replaced it with a second one, which started registering very low blood glucose levels. It said my BG was 2.9 when in reality it was 6.8. This went on for hours. I ended up closing the app last night to avoid the alarms going off overnight.
Luckily I still have testing strips on prescription and a monitor.
I have reported this to Abbott. They are sending me two replacement sensors. I’m sharing this so other people are aware there may be a faulty batch and to be careful.
Cheers,
Chris

Hi,
I use Dexcom myself and there are always similiar stories I read about failures. Unfortunately I don't think there is a perfect system available and all the CGM's have occasional problems. I had a similiar problem with me Dexcom G6 recently which I ended up by solving in the short term by going back to wearing the sensor on my arm rather than my stomach. I had been using my stomach for the last 2 years because I kept koncking the sensor off my arm . However after 3 sensors in a row all going low for no reason, I decided to use my arm again and now they seem to be working fine. It could have just been a bad batch who knows.

Thanks for your reply Marke
I’m sure there is no perfect system. To be honest, I’m quite enjoying some time just doing old school blood testing. New sensors arrived this week, and I haven’t fitted one yet. Sometimes I take a break from CGM. It helps to reset me, and get me back into a better basic routine following the DAFNE principles. And my control always improves. I have a tendency to fall under a false illusion of control with CGM. I can check my blood glucose a bit obsessively and sometimes over correct, and then pay the price for it! I think CGM is a wonderful thing, but I have to be careful I don’t let it affect my habits and behaviours.

Hi,
Oh yes, I can over correct as well ! I suspect a lot of people do. It's a difficult balance between too much knowledge and too little. Like most people the CGM alarms can drive me nuts sometimes, repeatedly buzzing for a low or a high, however the devices would not be certified by the MHRA unless they did this. The logic being better to annoy us than let us have a Hypo . Still having a pump and a CGM manage my night time blood sugars is worth the hassle every time !

You’re right. The hypo alarm is essential, especially for overnight. I will be fitting my CGM sensor again today. Been enjoying life without it, and BG has been very stable. But finger pricks are a pain, so it’s time to change back. Hopefully maintaining the routine and discipline I’ve re established by going back to basics for a bit!
