don't know if its just me. Been using Dexcom for years always on the dot. Seems recently Its been way off for me. not as accurate. off by 50+. wondering if its a quality issue or just me. anyone else notice their readings ? I have received new supplies last month.
Been on the G4 for almost a year now, and I've never had it be near as accuarate as the 13% MARD they claim. In reality, it's about 30-40% off. I can only hope that the next version improves significantly.
I've been talking to Dexcom and they have been great. I've tried 2 different meters, but the same model since it's the remote-control meter that comes with my Animas Ping insulin pump. I can't really use any other meter since I need the remote bolus feature.
I do love it becuase 80% of the time, it's pretty accurate, but 20% of the time, it's just WAAAAY off. As with everything, it shoudl get better and better over time.
My most recent batch of sensors from Dexcom received 1/30/14 has for me been more accurate - and more long lived than previous batches. So far I've only used 2 of the 12 sensors. The first was on for 26 days and was consistently within 10-15% of my Freestyle Lite meter readings. The current sensor is on day 21 and will be restarted later this afternoon. I am wearing the sensor on the back of my arm.
I am not looking for the G4 to exactly match my glucometer since it is sampling a different substance than my meter. I do want to see trends and these it shows really well.
Yikes that's a little disheartening since I should be getting one of these in the next week or two for the first time.
Austin--even though it's inaccurate for me at times, the times that it is accurate and shows me patterns so I can better judge when to meter test is great. In other words, I am not even considering the thought of discontinuing its use if that makes any sense. I guess all I'm saying is that I expected only small variations from my meter like 20% or less each and everytome, and about 20% of the time, it's off by way more than that, but I still think it's a highly useful tool and beats walking around for the bulk of the day and night not having a clue where glucose levels might be at.
