So in another thread, a number of people mentioned that the sensors they'd ordered/received starting in January of this year are lasting a significantly shorter time (typically <10 days) than the sensors received before this year (or the 7+) which often lasted 2 weeks or more. The theory is that Dexcom has recently made changes to something on the sensor to ensure it fails sooner, and someone suggested we take a little poll. Would you humor me by answering the questions below to see if there really might be something shady going on, and Dexcom has made changes without informing users?
1) First, for those of you who've worn sensors and/or used a receiver received both last year and after January, are you noticing a difference in sensor life in the most recent sensors? If you used the 7+, are you finding a difference between the 7+ and the G4?
2) Approximately how long have your latest sensors been lasting?
3) Can you specify either the expiration date of these sensors (ideally) or if you don't have that info, when you received them?
4) Reference and Lot Number, if available.
5) To see if it makes a difference, where on your body did you place the sensor(s), and do you use an adhesive tape?
6) Those of you whose sensors are lasting more than 10 days, do you have any special tricks that seem to make them last longer?
Thanks, all...This should be interesting. They make these sensors so darn expensive for just a piece of plastic and wire, and it is a little upsetting to think Dexcom might be purposely forcing us to buy them more frequently.
ETA: I have noticed that when I've kept the sensor on after dropped readings, when it does come back for a reading or two interspersed with the ???'s, those readings are quite accurate. Very different from the 7+, where when a sensor started failing the sensor didn't have as much difficulty getting readings, but those readings became highly inaccurate.
