Type 2 Monitor readings

You will get a variation with any meter but they are accurate enough to keep your bloods in-check

Glucose levels are not static, they fluctuate, and as your blood is circulating all the time you will get different readings, even from the same finger, because of this.

So it's better to keep a record of your levels and look for trends over time, rather than wasting time and effort - and money(!) on test strips - pricking different fingers, though obviously individual readings can be important too.

I think the monitors are allowed to be out by +or - 15% by law and are still considered accurate. As Robbity says better to look for trends after certain foods. E.g does it tend to spike by a certain amount after eating something in particular or particular mealtimes or waking.
