Lines of the Bee
Yes, as you may have guessed: I'm talking about a Minimed Continuous Glucose Monitor, of the Paradigm 523 Revel variety.
A fellow Type 1 my mom knows up in Michigan (previous guest-poster known as Vampire Girl) had a number of extra boxes of CGM sensors that she wasn't going to use by the time they expire, so she pawned them off on me in hopes I could make some use of them. While I did put out a message in the Diabetes Online Community about the availability of some extra supplies, but after not hearing anything made the conclusion that maybe I could get some use of these myself.
Previously trial testing two of the three CGMs (as it was in early 2010), I'd tested out the Abbott Freestyle Navigator courtesy of my mom's use in late 2009 and then later did a trial-run of the Dexcom 7 Plus. I hadn't heard positive news about the Minimed, but wanted to try it out myself before making any final decision. Especially since I use a 722 Paradigm myself and it'd be nice to have pump and CGM all in one unit, if accuracy and everything else was the same.
So, the chance came at me and it soon became clear I'd be able to trial-run the Revel, courtesy of a loaner from the local MM pump rep Ryan Seller who I met at D-Camp last year. He hooked me up with a colleague of his and the trial test began a week ago. My first observation about the sensor: it looks like a bee, with all those strips. The CGM trainer laughed in agreement, then we moved on to the basics and got it all started.
In the seven days, I've been initially impressed with the Revel 523 CGM, which I've decided to name Larry The Loaner (you know, since it's a loaner device)! Though it looks like a bee, the first sensor actually didn't hurt going in and I hadn't had any pain or uneasiness with it in me during the initial days.
Then there's Accuracy... Well, it ain't perfect. But it's not expected to be.

The first week has shown some trends in morning "dawn phenom" highs, pre-lunch and late afternoon dips that I'd already suspected were happening. But having it presented in actual CGM line charts and data is like seeing documented proof of a long-suspected hypothesis. Sometimes, the glucoaster effect is present - particularly following meals, and it's certainly interesting to try and time the CGM and insulin delays with the food effect that are all combining to change the course of your BGs.
After day seven, my BG average for the past week was 157 mg/dL. Can't argue much with that, though I'm cognizant of the fact that it's likely because of the increase attention.
Larry is also looking forward to some guest-posts here, too, and word is at least one of his fellow CGMs may even be interested in stopping by and saying hello before long! So, stay tuned!
