I agree, i should look at every possible sources for being "off". I appreciate you mentioning it because I never actually considered it because well, the unit is new. But, i checked it just the same :-) (by using the solution -- is that the correct way to do it???). I have an extra unused unit of the same brand, as a stand by.....

I will continue to be vigilant with my blood sugar. Mrs.D and Glenntaj suggested the insulin test. I would want to have the test but I am thinking of a good argument to convince my doctor. some doctors no are so careful i. giving out laboratory tests.

Thank you.
