Accuracy of the FreeStyle NavigatorThe 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.
