braun and code free meter

[emmgeo]

I have two meters one is a Braun and the other is a code free meter, I have used both meters at almost the same time to experiment and the Braun is reading 2 to 3mmol higher than the code free meter. not sure which one is correct.

No home use glucose meter is really accurate . I think theyhave to be within 15% 90 % of the time .
Also blood is not homogeneous
If you are self funding the strips, I would just use the meter with the cheapest strips

I am self funding that is why I have two meters at the moment, I am using up the Braun strips before I start using the Code free meter as the strips are cheaper.
I have just remembered I have got some testing fluid for the Braun meter so will test the meter when I get home tonight, that should give me an idea if at least that one is working ok.

remember and check the date on the test solution, sometimes they aren't very well dated, also if its been open over a certain amount of time it shouldn't be trusted either xx

A bit better than that now. See https://medicines.necsu.nhs.uk/bloo...mplementation-of-iso-2013-accuracy-standards/

• 95% results must fall within ± 0.83 mmol/L of laboratory results at concentrations of less than 5.6 mmol/L
• 95% of results must fall within 15% of laboratory results at concentrations of 5.6 mmol/L or more.
• The 2013 guidelines also now stipulate that 99% of readings must fall within zones A and B of the Consensus Error Grid for type 1 diabetes.

That still means that now and again you'll get two readings from meters which conform which are 2 or 3 mmol/L apart.

(I seem to remember a report about actual meters in the real world being a lot worse than the original tested ones (because normally nobody does follow up tests and manufacturers make changes (which shouldn't make any difference) after the initial testing). I don't know whether that was satisfactorily resolved; seems obvious that checks ought to be performed on meters that people actually buy.)

Yes I’m a sense I’ve long felt that BG meters should really say ‘ish’ at the end of all their results, rather than suggesting pinsharp decimal point accuracy. Over the years I’ve certainly had ones where I know that if I didn’t like a result I could recheck a couple of times until I got a number I was happier with

Having said that the Contour Next meters I’ve been using for the last few years have been really reliable and seem far more consistent strip-to-strip.
