Differing BG Readings - Different Meters <>5.0mmol

I'm a bit concerned at the differing readings I have been getting from my BG Meters and wondered if others have found the same.

I'm not sure whether I can name the devices but the one I have been using for a couple of years has always given me what I thought were sound readings. And when I have ever tested twice they would be either the same or point something different, giving me a sense of accuracy.

But my diabetes clinic has given me a different brand, this has given me readings at least 5.0mmol higher than my old meter. And then when testing again dropped by 3.0mmol. On looking back in my diary this meter was one I had had before and it was exactly the same. This reminded me why I had gone back to my old meter in the past.

I got a new version of my old brand of meter and both the old meter and the newer version had near same figure on a test. With the same sample of blood I did a test on all three meters, and again the one given to me from my diabetic clinic was a great deal higher than my original and newer version of the original meter. We are talking again around a good 5.0mmol difference.

As I am not currently at a well controlled level and the figures are in the range of 10 and 16mmol or 21mmol if you believe the clinic given meter, should this amount of difference happen? If I happened to be below 4mmol, would the clinic given meter still be 5mmol higher? I find this rather concerning.

That's the problem. If and when you're more in the normal range, you should expect meters to give more similar (and useful) readings. When a meter says 16 or something I wouldn't read too much into the specific value: read it more as "too high". The meters and test strips are designed to be most accurate in the normal range and they're worse outside it.
