| | | Why I'm Giving Up on CGMS
 
And it continues like that, all night, every night, alarming every 25 minutes. |

| | | I talked to my doctor about some of the problems with "accuracy" that I have been hearing...she looked me square in the face and said "NO, they are very accurate."
I told her I would like to wait for the next few generations to arrive before I invest all that money. I do have hope for the future with this technology, but I wonder if they went on the market too soon.
I wore the Guardian? a couple of years ago when they first were being used by doctors. It was a 3 day test. She didn't like the numbers...I went home and analzyed my logs vs her printout. There were a lot of 50+ differences. (She didn't want to hear it)...also, I had to repeat the test since they tech had switched the Am/Pm setting my first day. That's not a biggy, but I found the overall training lacking with the doctor's office. |

| | | I think it is the accuracy issue she is complaining about Bluesky. Her meter is reading 97 and the CGMS has her in the 40's.
I am waiting for a more simplistic and accurate CGMS as well. |

| | | I see it all the time if I use the Freestyle meters. On the other hand, I noticed that it tracks very close to the OneTouch meters. Someone has noticed the same thing if I am not mistaken.

| | | So, are the FreeStyle meters "off" or is it the CGMS? |

| | | Thus, the reason I gave up on Dexcom. I was seriously considering switching pumps just to go with the combo pump/cgms from MM. Problem is that I really want some of the features that only the Cozmo has and now I see this. I think I'll wait...

| | | How frustrating for you! I've had days like that but not too many. I'm usually pretty accurate (within 20) between my Flash and sensor. I noticed when it's off by more it happens after I have to calibrate at a bad time. I tend to calibrate when I wake up, but if I'm low and have to ENTER BG NOW, but also need juice to get in the car and drive to work....my bg has raised before the calibration took full effect and then it's off a bit more and I get readings like your picture.
Like I said though, most times I'm within 20. I do look forward to the day that this is more accurate and dependable. It sure would be nice to be able to trust it completely! Though the same could be said for meters in general as well.

| | Hey funnygirl I had this same problemmo - my cgms going off every 25 minutes during the night was crazy and what was even more frustrating was it's accuracy compared to my One Touch Ultra!  Going through all this mission of wearing a cgms attached to me like a 6th limb, the stress (for me) of application and then ultimately getting inaccurate readings. Urgh.
I am however quite excited for future products. A slim line nano like cgms that reads every 5 minutes and even plays mp3!! haha

| | Funny, sorry to hear the sensors aren't working right for you.  I'd hate being awakened by alarms if they weren't accurate...
That said, I still question the validity of both the sensors & the meters. I don't feel that either are 100% accurate. I've known the Freestyle meters to read higher than my UltraSmart, but there have been times when the levels were quite off. I've had readings on one of my Freestyle Flashes that were 100 points off one or two times. When in doubt, check with another meter (if & when possible).
Again, sorry to hear about the troubles you've had. Hopefully in the near future, we'll see more & better advancements in this area.
