Interesting, I experience the same thing. I use two meters, one for BG and ketones, the Precision Xtra, and one for BG, the Freestyle Freedom Lite. The Freedom Lite is recommended by Dr. Bernstein. I find that the Freedom Lite consistently reads high, and the Precision Xtra is very accurate with any lab readings I receive. It may be that the strips for the Freedom are the key for accurate BG readings, but due to their cost, I'll likely not use this meter any longer. The Precision Xtra is dependable and consistent, but the ketone strips are very expensive. Since I'm in ketosis most of the time, I'm using it mostly for BG and will keep doing so due to the high readings of the Freedom. Live and learn.
