I agree that in the great scheme of things 10 or 15 min will not make much difference to the test but how about 1 or 2hrs ? If all you want is to check on how your levels are doing through the day then 3 or 4 random tests is fine but if you are trying to discover how a particular food /meal affects you then a test first thing in the morning and another at 11am after your lidl roll is not going to give you any useful information.
I agree, but at the time you made your post the OP hadn't admitted that there was a big gap between testing and eating, which is why I replied as I did. Now she has admitted that she doesn't do any pre-meal tests, it is a different story.

You are wasting your time I'm afraid. In order to test out food you must test immediately before you eat. It is the actual rise from before to after that is important in deciding whether that food suits you or not, and if it happens to be a big rise, then you have to keep testing until it returns to near enough where you started before you ate. Just testing once at 2 hours tells you nothing because you have no idea how high you spiked, and the spike could have been earlier than 2 hours, or later than 2 hours, or high but flat for a long time. There are so many variables.
If you are short on strips, then pick one meal a day to do the tests on, or consider buying your own meter and strips (Codefree being the cheapest)
