Accuracy of the FreeStyle Navigator
The latest issue of Diabetes care has published an article on the accuracy of the FreeStyle Navigator system.The authors did a comparison between the FreeStyle (reading every 1 minute) and a system to measure venous blood glucose (reading every 15 minutes).
And the conclusion?
Measurements with the FreeStyle Navigator system were found to be consistent and accurate compared with venous measurements made using a laboratory reference method over 5 days of sensor wear (82.5% in the A zone on day 1 and 80.9% on day 5).
This article also contains pointers to two interesting FDA summary of safety and effectiveness documents. One for the Dexcom STS system(PDF), and one for the Medtronic Guardian RT system(PDF).
Has anyone out there used this system and can post about it? I'm especially interested in what the software does.
Update: They've finally received FDA approval for the Navigator. I've posted on my blog with the details.

Bernard, I haven't been lucky enough to use the Navigator myself, but I found this blog very helpful--gave me a chance to see some software screenshots (oh, if only Dexcom would give us even that much!!):

For those who have used the Navigator, is it possible to re-set the receiver if you experience a sensor failure? I have been trying the Dexcom and I got a sensor failure within the first few hours of use and was able to reset the receiver and keep using the sensor. That would be very expensive to waist one.
