How important are use by dates on test strips? I test about three times a week (Type 2) so, thanks to an excellent and generous doctor, I've accumulated a number of test strips that are now about a year out of date. Can test strips deteriorate as I'm reluctant to dispose of these strips if they can be still used? I compared a result between an 'old' strip and a new one and there was no difference.
I'd be grateful for comments.
