Current Onetouch Ultra Easy hand book states meter is considered accurate when results are + or - 20% of lab results. That is the international standard that companies have to conform to.noblehead said:Hi Dave,
I didn't know they can be 20% out, where did you get this info? I have heard that they can be up to 10% out, but not the figure you quote.
Regards
Nigel

I'm not saying I want meters to be 100% accurate but I want tight control which is not possible when results can be 20% out. In this day and age it must be possible to produce meters to a higher standard than this without much of an increase in costs.

That's all I need to know, not that the reading might be out a point or so. By using the same meter ALL the time any discrepancies balance out - so they are as good as they need to be.
Dave37 said:In your later post you claim to be able to get very tight control, how is that possible if you aren't bothered that you BG is out by a point or so, that's not what I think of as tight control.
Dave. I don't claim anything ,I know because of my readings, how I feel, and what my HbA1c tells me. I don't assume that my Bg is out by a point or so....it may be out by a tenth of a point or so, that's all. I think anybody, as I have, who has 98% on target blood sugars must be getting good control. Sadly because of an unrelated condition that control has been decimated over the last two months.So, I am now uncontrolled ! What I do know is that once my treatment stops I WILL go back to that 98% - believe me.
I wish I had your awareness of what my BGs are doing, not all of us do.
Not quite sure what you are getting at there Dave, I have no idea what YOUR Bg levels are. :?
I'm a type 1 on a pump and have tried everything to get good control. If I knew why my control wasn't good I could hopefully do something about it. The point I was trying to make was, if I'm doing a correction dose and my BG is out by 20% that increases my risk of a hypo.
That 20% figure is a maximum ! , I doubt very much that ANY meter is out by that much, they are just covering their backs in case anybody gets an odd reading. My meter the Lifescan UltraSmart I took with me to the Hospital when I had my HbA1c done. The result from my meter which I used at the same time to test the accuracy was only 0.2mmol/l different.....?? Nothing like the 20%+- reading you seem to think is what all readings are ??
My number one problem at the moment is I'm having to many hypos and may be a more accurate meter would help. I'm not blaming everything on the meter but every little helps.

You're lucky to have such good control but you seem to think my poor control must be my fault
I wish I had your awareness of what my BGs are doing, not all of us do.

I mean my Hypo awareness is poor and I don't always know when my BG is high, unlike you.

I didn't say all meters are out by 20%, I said that was the international standards they have to meet. I agree Lifescan are one of the more accurate manufactures, although Richard Bernstein recomends Accu-check which is why use them, I trust him. I'm not sure HbA1c can be compared to your meters results as they are a 3 month average where as your meter is giving you a current result.

I have the same problem too. However I don't rely on the meter to tell me if I am hypo or not. I rely on my hypo awareness to tell me what is happening. The meter is the tool I use to confirm what I really already knew. I am having a hypo ! Same if my readings are high, I know how I feel, so when I test it again confirms that I was right.
It would as you say be nice to have more accuracy, but as a pump user surely you have had plenty of advice from your DSN/Endo about getting the amounts correct. Could this really be the cause of your problems ? Not a misreading meter. I notice you haven't asked for any advice in our own Insulin Pump forum, we have some VERY experienced members there who may be able to assist you in getting the numbers and dosage correct. Worth a shot ?
