While CGM sensors are approved to wear for 7 to 14 days, how many days do you find your CGM sensor gives you the most accurate readings?

I think I have been wearing a Dexcom sensor for at least 14 yrs and my sensors have lasted 10 days every time except one.
For me Libre 2 is accurate enough from start to end of the 14 days its programmed for.
I usually get 20good days. Hit 30 days once. Usually about 2 days after restarting for the 2nd or 3rd time it craps out
Dexcom G6. Just changed after 30 days. Usually get 20+days (2 restarts) before it craps out.
Hi sometimes wish was back on G6. Like you I could usually get 20 days. Actually liked better that the G7 I have now in some ways. G7 says use upper back arm. Have knocked few off. Never happened with G6. I get a lot of compression lows at night. But like the flat smaller device. And the zero warm up time.
Libre3 last for 14 days but the first day is squirrelly. Why the latest sensor needs a 12 hour warmup is beyond me!
I am still using the Dexcom G6 which lasts no more than 10 days. With arthritis in my hands, I cannot do the steps involved in reusing the sensor. I get at most 8 days of reasonably accurate numbers when comparing with glucometer numbers.
I had to chuckle at the facile UTube videos showing a blithe and simple extension to the G6. Arthritis drives a stake through that thought’s heart as good as any vampire.
I use Dexcom G6. I usually get the full 10 days out of a sensor. Occasionally, I get on the goes out on day 7, 8, or 9, but not often. There was one period a few months ago when I had about 5 different sensors go out early. That seems to have passed. I figured it was a bad batch.
G6 is a 10 day wear
I use Medtronic Smartguard and it sometimes lasts the full seven days but usually starts getting glitchy at 5 to 6 days.
Use Dexcom G7. Seems accurate for the full 10 days. Sometimes a little off for the first few hours.
I use the latest Medtronic Sensor 4. Approved for 7 days but I usually push it to 14 days. Readings are usually accurate for the duration. I have never tried to push it past 14 days, but a Medtronic rep told me of a colleague who wore it for 21 to 28 days.
Usually 10. But when the rare failure happens, it is a big deal. I really appreciate how well the Dexcom works. No matter the tech, I still need to be on my toes and be prepared to check the math, and whatever else to manage insulin levels!! Would love a 14 day routine!!
We had a batch (maybe a month or two) that really only lasted 7 days, but lately all sensors have lasted the full 10 days (knock on wood)!
If you have ANY and I mean ANY issues with a Dexcom sensor not working call them and explain. They will replace almost anything free. My son ripped a few out swimming. They replaced both. Had 2 bad sites. They replaced them all!
I’ve got my
G6 a couple times to do 20 days by fluke but kept forgetting the trick to get it to do it. Any suggestions to where find best way or share your secret?
Unfortunately I tried and could not find a G6 workaround. You cannot pull out and put the transmitter in because it will remove the sensor so you can’t even swap transmitters to allow it to last longer. I hope you have better luck finding a solution.
You can pop out the transmitter with a test strip and restart.
Libre 3 works for the full 14 days the way it’s supposed to. I haven’t been able to use my IPhone with the 3. I wish they would fix the program, so I wouldn’t have to carry the separate cranky reader.
So much depends on the sensor location and who knows what other factors. (Also I use calibration mode on my G6.) I recently restarted a 10 day sensor and had accurate numbers for 18 days. My current sensor has been off quite a lot, by as much as 20-40 points. Go figure!
A better question is “ do you check the accuracy of your cgm?”
Wear the G6, usually for 10 days with the first 12 hours a definite wild guess requiring manual meter testing.
With my Dexcom G6, it maxes out at 10 days. I have NO choice but to insert a new sensor. I the only CGM that had a workaround where you can fool it into believing that it had been changed. I believe it was a Medtronic 740 or something.
the G6 can be restarted pretty easily. good YouTube videos showing how. I do it every time and it works well for another 4-8 days.
Good question: as a longtime Dexcom user, I have experienced a disturbing trend of sensors recording inconsistent readings beginning on or about day eight of a ten day cycle. In addition, sensors “lose” connection more frequently around day eight. DexCom has politely replaced failed sensors, however, the call wait times and overseas/global technical support teams are time consuming and frustrating particularly when compared to service experiences. The sensors are often unreliable for dosing decisions after day eight.
The CGM brand I use expires at 10 days after starting.
I don’t do finger pricks or calibrate. My Dexcom G7 lasts a full ten days but I haven’t been checking for accuracy. Maybe I should/will.
If you are using, a Dexcom (Dex) Sensor you can only get 10 days on a G6, and 10 1/2 days usage on a G7,
I get about 10 days of good readings. on my Dex G7.
With dexcom G6 the first 24-36 hours are often really far off the mark. After that the accuracy is fairly good, but often the last day or two there seem to connection and reading g errors.
I use a Dexcom G7. The sensor expires at 10 days + 12 hours. It is not possible to extend use longer than that. It is financially foolish to shut it off shorter than that. I find readings to be relatively constant/correct during this usage window.
My dexcom G7 sensor doesn’t give me any options. They give you 10 days plus 12 hours g
race to get a new sensor on after that it’s dead.
5-7 days. First day is always off z first 12 hours. Also when I restart a Dex it is also off 12-24 hours and even then still off 20+ for subsequent days. Calibrations do help bring it in line.
??? The G7 cuts off at 10 days so that is as long as it can be worn. Am I mistaken?
you can restart it – there are good YouTube videos showing how, it’s easy!
oops, sorry! thought you meant the G6.
I purposefully have remained on the G6 as I consistently get 20 days per sensor with the restart. Yes, the first day of the restart is a bit whacky but I just calibrate several times until it settles down. I just purchased an Anubis transmitter so am looking forward to the ability to not have to change the transmitter every 90 days. I know there will come a day when the G6 is no longer available but until then, I am happy with this CGM.
I do the same. First day is usually off for awhile, whether it’s brand new or a restart, but I calibrate and it settles down. It then works great for at least the first 10 days. After a restart I don’t always get another 10 days but I often do.
Now that I have the Dexcom G7 it has a 12 hour grace period. So of course I take advantage of that 12 hours and change out every 10.5 days.
Dexcom G6 and G7 are 10-day CGM sensors. I normally get accurate readings through the 10th day. Occasionally, at the end of the 9th day, the readings will be erratic,
