MM is not as good at catching lows. But that 5-point bounce, upwards from 65 to 70 (BEFORE they terminated declining bG) is really weird.

The original study was done in late 2005, before Dexcom was released. And I don't like the layout of Dr. Clark's grid, but he shows the actual data points on a graph (rather than just the "A+B", "C", and "D" proportions).

The study was excellent, even though the number of test subjects was a bit small. I have high confidence that the conclusion (Navigator shows SIGNIFICANTLY better numbers during rapidly developing Hypos) is correct.

Now, why is the FDA still preventing us from getting the apparently superior device? I've no idea, but there's still something about Navigator (or it's requested protocol) which the FDA doesn't like at all.

But what is it that the FDA doesn't like is the million dollar question?

they're STILL fighting about 5 days (versus the mere 72 hours the approved devices have approval for).

Maybe the FDA wants to actively PREVENT off-label cheating of the timer expiration in future products, that would IMO be tragic. I *WOULD NOT* be able to use Dexcom continuously on a $35 per every 72 hours schedule, so the FDA would simply me pushing me back to where I was a year ago: Lotsa 50s, 40s, even a few 30s and 20s. Lots of Glucagons. (6-12 per year.) If I was foolish enough to drive longer than 15 minutes without a test, other innocent people would be at risk of my passing out at the wheel and killing THEM.

For a really weird case such as mine, where nights can go 200+ or 30- for no apparent reason, life without CGMS is a DEATH SENTENCE. (Not immediately, but poor life expectancy would be pretty certain in the long term.) Without question CGMS is more valuable for me than my pump.

Of course, this is only a guess. Until the FDA rejects the application and releases the documentation of their decision, very few people really know what they're thinking, and those people are legally obligated not to tell anyone. (It would be insider information, the stock markets would have MAJOR problems with it's leakage.)

Hello,

I have been part of the Abbott Diabetes Care trial for their Freestyle Navigator Continuous Glucose Monitor for about 30 days. I gotta tell you, I LOVE this thing!:p I am most impressed with the accuracy, but there are a few cons, that I outline in my relatively new blog at http://diabetesselfcare.blogspot.com/.

I decided that this was WAY too cool to keep to myself, so I have posted details of my experience so far and have included pictures as well.

I only wish I got to keep the CGM when the trial was over! I'd love to hear from other folks using CGM's. This is the best thing since insulin!

The pictures are most helpful. :cool:

This is why it's important to keep your low alarms set to a safe level on current devices... like 100. I think it's better to prevent lows, than to track them!;)

This is the best thing since insulin!
I don't think so. The switch from "pissing papers" (which can only tell you whether or not you were WAY High 3-6 hour ago, absolutely NOTHING about where you are now) to at-home finger-stick bG testing was bigger-- but maybe this revolutionary advance occurred before your time.

A Better Thing than faster-acting insulin analogs? YES, I think so.

A Better thing than pumps instead of shots? YES, I think so.

But not a bigger thing than at-home bG testing. THAT was even more revolutionary in my/our ability to care for ourselves.

As for hearing/chatting/hanging around with 'other folks', this is a very good place right here, thanks Jeff !!! :D

But the yahoo cgms board at http://health.groups.yahoo.com/group/diabetescgms/ is also very busy, and a bit more focused. Although, focusing on the less capable AVAILABLE devices (MM and Dexcom) and their problems/issues/workarounds might not be what you're looking for, you spoiled-by-Navigator-trial little vixen! :D ;)
