[QUOTE="Oldvatr, post: 2348882, member: 196898"] I looked up this meter and it is made in the USA. I have read the specifications for this device and nowhere (absolutely nowhere) does it give any indication of accuracy. There is no reference to any standards such as ISO, which European and UK meters are mandated to be compliant to. I did find a throwaway line where it does declare it to be Plasma calibrated hidden in the owner's booklet so it should track most modern meters being sold today, but there are no indications what level of certification it has been passed to or any FDA reference. Most meters that meet the ISO requirements here in the UK can be traced back to an actual test report that they submitted to get clearance to market in the UK or EU, but it is not declared on the website. They quote the FCC standard it meets but that's all it seems. Even in the UK most meters will measure to +/- 15 % of true reading, so two meters on the same blood spot could be 30% different and still be considered to be accurate. So at 10 mmol/l you can expect the two results as reported to vary between 8.5 to 11.5 and be claimed to agree. Sorry, but that is a fact of life. I have 2 meters myself, and they are currently varying by 2 mmol.l (UK) and that is pretty constant so if I do not see that I suspect a misread by one of them. You need to record both meter results and average them over about a month before comparing them to find out what the offset might be. It becomes difficult where I am getting near hypoland, and I get one meter saying I am safe to drive my car, and the other telling me to seek assistance. I am hypo aware, so I then resort to how I feel, and munch a snack to make sure. Edited to put units into UK not USA Edited to correct a numeracy error [/QUOTE]
