No machines, even blood testers are 100% accurate-they are all allowed tolerances of error...
As a sidepoint, did you realise that you may not even get a litre of petrol from garage forecourts? Again they are allowed tolerances too and its best to fill up your car slowly??
Also our bodies can react quite differently under stress and for example... in hospital pre my mastectomy reading I had a cgm in. Accurate is superb with it. In hospital with stress it was completely inaccurate to my bloods.
After op I put a new one in next day and perfect again. My DSN even came upstairs to see me to say "see we got you safely to op" -trouble was, the cgm readings she was seeing were inaccurate and when she arrived I was going iow (my biggest fear)....
If unhappy with accuracy of libre do all the things they require to complain and if you are not happy with their reaction you can always report to MHRA as problems with medical equipment.
Unless you take time to report things to MHRA then unhappiness from people will always continue...
Yep, n when you've had a double mastectomy ad lymph node removals and nobody can give you a true idea about whether having a libre stuck in arm could cause lymphodema or not, its another worry.......
My Prof bc and diabetes chap says as lymph nodes were only samples (not full clearance) and clear then they thought bp and tests could be taken from arms but no research data on finger pricks or cgms but they thought low risk!!
(Not their risk though is it??).
Thanks for that. I shall do some more tests to see if I get the same.I found once calibrated it is linear.
For me I've found it was relatively accurate when I was high but now I am lower it doesn't do the higher end well ie a 6.9 on sensor is often 8.5 - 9.5 and when the libre says 4 it's usually 5.1 so in theory out of tolerance. But if sensor says 6.9 the meter usually agrees...If it wasn't for the awesome convenience of being able to test wherever, whenever you want, I'd dump it and just do more finger pricking. But I've got in the habit of testing at night. If/when I wake for a pee I test and take appropriate action. I'm out at a rugby match on Saturday, and testing will be so convenient. But what cost?
How have you found upper end inaccuracies? I haven't really checked. But if a 8 or 9 is really 11 or 12 I would be very unhappy.
