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.

All home glucometers are considered only approximations for testing.

Here is a link explaining:

Even in this article the explanation of "accuracy" is difficult to grasp IMO. So getting really picky about various readings that vary from day to day...may just be a function of the strip that day and/or the meter itself.

I do know that very low levels are not accurate. Most glucometers explain that.

So keeping any log or track of levels...is quite fluid...don't get overly concerned about slight changes up or down.

Keep in mind your pancreas can change too...many type II diabetics eventually tire out their pancreas and may need a basal injectable insulin.
