Freestyle Libre

Unfortunately I think it depends on the individual as to how accurate it is.

I have found the Libre 2 is usually a few points of a blood glucose reading most of the time although there was the occasional time when it was 2 or 3 mmol/L difference but whether the Libre 2 was inaccurate it or the BG meter, I don't know.

Others in this forum seem to have had greater inaccuracies though.

Hi Folks.
I have been trying to access the Libre sytem for some time, there have been delays after delay with the induction and assisting me in starting the use of the gadget. I have opted to go for a 1-1 with the local iabetes centre altough this in itself is likely to take even longer. However, from what I have seen on these posts there seems to be question over the accuracy alongside the reliability. I have battled on with glucose testing for donkeys years and this seems to offer consistent accuracy and reliability, so the question is - "Are these worth the effort" as it maybe a level of trust on a device against the accuracy of glucose testing.

I have found that the readings aren’t far off actual BG except for high readings. I find the low alarms very useful as I was losing my sensitivity to hypos. Also my fingers are not sore anymore! I can play my cello without pain now. As for being active, I noticed that Nikita, one of the Strictly Come Dancing professionals, has a Libre sensor. You can’t get much more active than that!

I get it, but I also understand that I also inject frequently, so the view for me is that I will continue to do both for some time to come, there seems to be no better or accurate way to go.
I do understand the replies and pleased for the input from fellow DAFNE experienced folks. Many thanks, John

I have been using Libre 2 for around 18 months, I find the additional information it gives you both useful and worrying. Diabetes has taken over my life where for the past 25 years using a glucose meter I had a good HbA1C but my diabetes did not rule my life.

I recently discovered the Libre readings at the lower end can be very different to BM (which is gold standard). Unfortunately no consistent pattern and often occurs in situations before I have taken corrective action, so not due to delay on Libre. In the past I have corrected unnecessarily resulting in a high glucose reading. As a result I am now checking any low or high reading on the meter! High readings generally match as do normal range, but low glucose readings can be as much as 3 different ie the difference between normal range and a hypo!!
How do we stand for driving? Would the law say we were hypo? It’s a worry and I am quickly loosing faith in the system.

With driving you are still required to do a finger prick test. I always try to make sure this is above 7 before I drive so it’s got somewhere to go if it starts to drop. I agree, if you get a low reading but don’t “feel” low then you should double check. Mine is usually not far off.

Hi All, I am amazed to hear of the inaccuracies that the Libre sensor is giving some people. I have not used it myself as I use a Dexcom G6 which is 100% accurate every time. Have you tried using another sensor @lucy1gus2?

Unfortunately the NHS will only prescribe the Freestyle Libre. Dexcom is too expensive!

Hi Annette, oh gosh. That's weird as I get my Dexcom paid by the NHS along with my pump. I didn't realise that about Freestyle Libre. That would of course explain why there are so many people using it. You learn something every day with Diabetes it seems!
