I recently was given a Dexcom G6 trial from my Endo’s office and upon setting up the initial sensor & transmitter, I had instant issues post-warmup.
I had my iPhone XS Max well within 20 feet of my sensor, I made sure I had it in an optimal spot on my abdomen, and I called tech support about an hour after I noticed I was having signal loss issues. When I didn’t have signal loss issues, I had repeated 40mg/dl “severe low” alerts when I was really 132mg/dl and 123mg/dl.
The first tech support call suggested I calibrate 3 times at 15 min. intervals and that it should correct itself, it didn’t. I then was receiving high readings of 234mg/dl and upon checking with my finger sticks I was a healthy 170mg/dl. I began to lose signal AGAIN (ughhhh, what the hell. SO frustrating… esp. for a beginner) so I made one last call to tech support. He asked me if I calibrated, I said yes. (Later, I did some reading and apparently you’re NEVER to calibrate a new sensor? What’s the actual rule-of-thumb here, then? Any insight on this would be great as I am still learning the CGM way) After this, he quickly explained he was putting in an order for a replacement sensor and that I should remove the current one and wait 3-5 days to receive the new one in the mail. after I had removed the sensor I: A.) Read online that you may experience fluctuation in the first 24 hours of using the sensor… well crap, I already removed it as tech support insisted. B.) Am unsure if tech support’s initial call may have absolutely thrown off my sensor due to their suggesting I calibrate a brand new sensor… and C.) I have iOS 14.6 running and I’m seeing on the website the G6 app is compatible up to IOS 14.4.1 - could this have been my issue?
Any opinions on this matter would be greatly appreciated, as CGM devices seem to be alllll greek to me.
