for me I use code 16, seems to be working for me, guess we will see in April when I get my A1C done. at least for now feels right. I have not checked it against a different meter but it was lower then when I got tested at the hospital.
With all my testing - the new strips read with code 16 what the old strips read at 17 or 18.
I just got my new strips...I see no difference and am still coding at 18.
Can someone please explain coding? We set it to what the test strip bottle says. How do we know if we need to do something different?
