Hi folks

Another question requesting advice if I may. I was issued a meter by my GP upon diagnosis & my DNS is fab. She has allowed me to order 100 test strips at a time. I tend to use this monitor the most. However, I also bought myself a Codefree meter so I can carry it with me at work or when travelling. On a couple of occasions, out of interest, I've tested on both meters. On these occasions the BG results are never the same. One meter might say 5.5, the other could be 6.6mmols. This is just an example, but the difference can be as much as shown. When testing like this, I often use the same blood sample so can't understand the varied results. I tend to test again & take the average reading, but it's not ideal is it. Have other people found this has happened to them? I've decided only to use the results of my GP prescribed monitor to record my BG. Still, it's concerning that my CodeFree device doesn't replicate the results. Any advice would be welcome.

Hi Alison

Any meter is only accurate to within 15-20% at the extreme, although most results are within 10%. That's just a function of the technology and the price. So let's say the real value was 6.0, then the 5.5 is about 10% low and the 6.6 about 10% high. Some batches of strips do seem to be anomalous too (Codefree ending in 44 for instance). So individual results can be a bit off, but over time the trends should still be valid because you are taking a larger number of samples which should form an array around the true values.
