I switched over from using an Omnipod and the Dexcom G4 Platinum system to the Minimed 530G with Enlite back in October when it came out. Initially my Enlite sensor seemed to be comparable to the Dexcom but over the past month it has been horrible. The numbers are often 100-150 points off..showing that my blood sugar is really high or really low when it's not. My Dexcom numbers were spot on about 90% of the time, often within points of my finger stick..so this is frustrating!
Has anyone else started on the Enlite and had the same issues? Do you have any suggestions? I'm going to call Minimed this morning because I received yet another calibration error and it actually shut my sensor off, while driving to work for the day of course :)
I've only ever used a MM system (first CGM in 2007), but I've heard quite a bit about people that switch FROM the dex to MM have calibration issues. Apparently, with Dex you can calibrate at any time. This is not true with MM. Also, you may have a bad box of sensors, so definitely call MM. They'll ask for the lot number and a bunch of troubleshooting questions.
I had similar issues as I was calibrating too ofter due to the fact that my glucose meter was automatically sending the readings to the pump and then accepting them as calibartion for the sensor. If not already done so, you need to turn off the meter option from your pump and calibrate the sensor only when static and around once per 12 hours.
In November I switched from using a MM522 + Sof sensors to an Animas Vibe + Dexcom. Although I used the older MM sensors and pump, I know several Enlite + Veo users and am familiar with their experiences. The Dexcom Sensors are far superior to the Sof Sensors - I find them amazingly accurate (like you I reckon plus/minus 10% of a fingerstick >95% of the time), easy to Calibrate, simple to use and foolproof. I averaged just under 3 weeks for each of my first two sensors. With the Sof-sensors I was averaging around 8 days per sensor - the most I ever got was 13 days.
None of the Enlite users seem to get any better lifetimes than with the Sof sensors although they are more comfortable to insert and a little more accurate. One of the Enlite users is due a pump replacement and will be switching to a Vibe. The other has had endless sensors conk out at around 4 or 5 days and is planning to buy the separate Dexcom receiver and use with her Veo.
TBH, I find the Vibe with its awkward menu system an annoying pump to use compared to the MM but I am happy to put up with the inconvenience in return for the performance of the Dexcom
