Default Hello. Problem with freestyle libre

Hello. I am Mary.
I am a new member. I live in UK.
I have noticed that the readings on my Libre Freestyle readings are consistently lower than the true readings taken with my blood monitor. For example, Libre will register as 'Lo' but blood monitor reads as 5.8!
Is anyone else having problems with this machine?

Hi marycarty, I am a type 2, don't use insulin, so can't help you with your Libre issue. Just wanted to welcome to the forum.

We do have a member in Australia that has posted about her Libre recently, maybe she will be up and about in a bit and be able to offer assistance. Her user name is kyteflyer. You can probably use the search function to find posts with Libre as the keyword to find posts/threads of her and others about their experiences with this CG.

Welcome Mary. I'm interested about the Libre Freestyle. I see the commercials all the time. I don't think my insurance covers it, so I'm still sticking my finger.

How long have you been using the Libre?

Hi, Mary. I have found that my readings were, at times, wildly inaccurate, and at others seemed to be spot on. The rule of thumb is... if you get a reading that seems too high or too low, check with your blood too. The sensor before the last one was a nightmare, anything from 2-5mmol off the mark. As an FYI I was using the Libre reader to do the blood tests as well. Strips from the Optium Neo are compatible... so I knew it wasnt a difference between readers, which can sometimes confuse.

Sadly, there does not seem to be a solution for the inaccuracies, Abbott has to do a lot more work to get it happening. Then again, perhaps it never will, in the sense that the sensor takes readings from interstitial fluid, and blood is always more accurate. I think its about an hour's difference... which can be a bit of a worry if you are going extremely low, or extremely high.

I have chosen not to use it anymore, I've given it a good trial for 3 months or so, and notwithstanding the issues of it falling off, being knocked off in doorways, simply not working at times (for which they will replace free of charge) ... I can't afford it on the long term. $92.50 per 2 weeks is outrageous and there is no subsidy in sight, here in Oz.

TL;DR if you get unexpected readings, always do a blood test to confrm.

Hello Mary - what you describe is pretty typical of the Libre Freestyle - My sister had the exact same issue - her monitor was always reading between 5 - 8 and yet her A1C was over 8%.

This is why I never bothered getting one. There was a lot of hype when the product was released but I think the reality of the device is starting to reveal itself. It's too bad.

With someone like myself who has lived as a Type 1 for the last 53 years and uses his readings to dose insulin and what foods to eat or not eat - such a lack of accuracy could get me in to a lot of trouble.

Hopefully the technology will improve eventually.

The main problem I have is that after going into a coma about 15 yrs ago, I no longer get any warning signs of hypoglycemia - so it's very important that I can have an objective check on my readings at any given time.
