My strips say I should get a reading between 22 & 52 for level 1 control solution. This is a difference of 30. This seems to be a large range. My doctor wants my reading to stay with a range of 10.
True Metrix Control

Very simple to use. It doesn't take very long to do. I always do controls 1,2 and 3 each time I open a new bottle of test strips, any time I think my monitor isn't working properly and if my glucose is really high or really low. The price is excellent!!!
