It seems the meter manufactures are good at adding features, but I have never seen report on their accuracy, which is my key concern. Is anyone familiar with the results of any studies that evaluate the accuracies of meters? I have 3 of them, all made by the same well known, manufacturer and can see some disappointing correlation between them using the same drop of blood. I think I heard several years ago that the FDA was going to be setting tighter requirements on accuracy, but have never heard whether that in fact happened, and if it did, has there been any improvement?
