I have not yet been formaly diagnosed with diabetes but have been told I have insulin resistance. I have two meters. Walgreens TrueTrack and the One Touch Ultra 2. I was very surprised that the readings from these two meters are consistently 30-40 points off from each other - the TrueTrack is always lower. That is a very big difference. I called each company and was told that the variation between two meters can be as much as 30% and still be considered accurate and that the variation between a blood glucose done in the doctor’s office and a meter should be within 20% of each other.
So I have a meter that tells me. after I eat, my BG is 125 and the other says 165, what do I believe? I think I believe the higher one as I get a jittery feeling after I eat more than 20 carbs.
I will be getting a BG done at the doctor’s office in two days so I will know which meter is closer to that result…if either.
I have done all the tests on each meter to be sure they are working correctly. The test strips and the test solutions are all new. I wash my hands to be sure there are no sugar molecules on my fingertips. Are there other tips to know about getting an accurate reading?
