What is the normal variability for a blood glucose meter?
I recently bought a counter low blood glucose (the "TrueTrack Smart System" kit) on the Internet to check my blood sugar after a parent has been diagnosed with type 2 diabetes. Since I have no symptoms and am not overweight I expected just to be reassured, but I found my fasting glucose 8hr several days seemed to range from 98 to 124 Information prediabetes potential. However, this morning, I became confused about how to obtain a reading of 144 well not having eaten for more than 12 hours. I decided to do several tests in a row and the results were as follows: 144 130 117 111 126 110 104. I made sure my fingers were very clean and dry and of course used new strips and lancets every time. The counter was not supplied with the control solution of glucose, but does not have a test card, you can insert into the port of Gaza, which reads and then "OK". Ma question is, what is the normal range of reproducibility you can expect in readings from a meter, and do I consider these results and discard?
The FDA allows meters from the house to vary up to 20%. Even high scorers will a change rather high during testing of this kind. Also, remember that the blood sugar is a moving target, so that even a few seconds later, your level may be different.
