We frequently mention that the FDA allows glucometers to vary as much as 20% higher or lower than what a lab would get.
Here is a spreadsheet and graph on Google Docs which has a graph of the range, plus a table of numbers used to make the graph, so that you can see what it looks like.
On the table of numbers, you will see that as the glucose values rise, the possible range for the real value expands.
