Libre Sensors - Try again in 10 minutes?

I’ve been finding with the Libre2 that the odd messages start to get more frequent- or completely insane - when the reader is getting low on battery. That occurs more frequently with Libre 2 if you’ve got alarms switched on, at least on the reader. “ Sensor not found” seems to be a common one. “Sensor out of range” is another, with the reader in the top pocket of my shirt on the same side as the sensor.

I find that the adhesive lasts just over 14 days, then gets a bit unreliable, so I never apply the sensor early. I’ve never noticed any particular unreliability after waiting the hour after application.
 
That is interesting i find the sensor well stuck on after more then 15 days also with MM 2 attached .

Abbott are replacing both and they didn’t want either back - usually a sign there’s a lot or batch that are a little out.

I will likely contact Abbott If I have any further issues with this sensor.

What’s the error message you’re getting ? Could be the filament bent as inserted or levels maybe changing fat or just the 24-48 hours sometime settling in period.

Hopefully, this is just a settling-in period after the initial calibration. Normally when this error is persistent the daily graph contains several large gaps in readings or fails to record anything from the previous 8hrs.

I kept getting glucose unavailable try in 10 min error. Which if look you look in settings and the system status it’s E3373P

Yes, this is the same error message. I've been wearing the sensor for about 24hrs now and must have had half a dozen of the E,3373,P error. That being said, it didn't occur whilst at work, and only once this evening.

Hi Dan I forgot I was going to send you a pic, this is my favourite spot and loads of room son both sides, best of luck with the libre2’s

Thank you Paul. I wasn't sure when I had to replace my sensor y'day, so it is currently about centre of the pectoral area. Certainly more comfortable than the recommended site on the arm, and I've got waterproof tape to cover to avoid errors caused by water damage.

I do it there too, keep us posted how you get on Dan
 
Update: Libre 2 sensor on chest seems to be going ok. I've had 1 further read error since yesterday, although I think the readings seem higher than those when the sensor was on the arm, in comparison with BGs. I'm a little concerned as well about damaging the sensor whilst in the shower. I do have micropore tape to cover around the sensor, but possibly a different option may be better suited for this site?
 
@trophywench I guess you’re right about men’s attitude to the wings.
@danielmg I had a strange situation after applying my first Libre2 it bleeped about every 30 minutes for most of the night then stopped the next morning, no problems since and it’s really useful having the extra reminder. My BS is high at the moment as I’m on strong pain killers
 
I don't take the reader to bed with me - learned that lesson years ago with BG meters which beep at you after they record a high BG until you test and it is no longer high enough to activate the reminders. However as long as a Type 1 whacks in some insulin as soon as they realise their BG is 'silly high' it can take hours to reduce back to normal so as long as the insulin went in and is being absorbed, no need to panic and better to get some decent sleep, which non-D husbands also find helpful when they have to get up and go to work tomorrow morning too.

So - I charge it overnight same as the phones and anything else eg toothbrush, Pete's 'electric' razor, my previous pump handset/meter .......
 
Update: I had the first Libre 2 sensor on my chest for approx. 6 days. I woke up this morning for the first scan and received error 'er3,363.P' - sensor could not be found. I tried scanning multiple times but to no avail. I've never had this error code before (any experiences with this?), and before I went to sleep the sensor was working fine. I've therefore had to change sensors 3 times in less than 2 weeks because of errors. I've contacted Abbott to try and get a replacement and will hear back in the next day or two.

Not an alarm I’ve had either. But I only ever wear them on my arm. 3x Libre 2 so far and they have all run the distance without any problems (though the very first one was a bit flaky results-wise and got replaced)
 
My first Libre2 was a pain initially but I think it was me and my phone. I switched it off, closed and redid all the parts of the phone that allow access, there were several buttons to press but since then it’s been fine and oh so useful with the night lows
 
Out in garden earlier with phone on charge in living room, wife shouted out window that phone was alarming, came in & message said bg going low, scanned & it was 3.8 with downward arrow, great that phone still picked up sensor from so far away.

Hey Dan, any errors starting with 3 are filament related, it sounds like the sensor has moved for some reason, I’m on the 4th since I quit the pump and never had a hiccup with them so far

Thank you Paul. I've sent all the required info to Abbott so hopefully will hear back soon. I don't know whether this is an issue at all, but I mentioned to Abbott that were error codes in the log from well before I even had the reader (as far back as January 2020). Likely just testing/calibration of the reader, but thought it worth mentioning just in case.

I've currently got my sensor below my chest (almost similar to what you had recommended earlier Paul), and I haven't had any issues as yet. I have however applied a transparent dressing (Cutiderm) over the sensor to protect from any possible water damage. Next time though I'll apply closer to the midline as I find that it can be a little compressed when sleeping on that side.

Fingers crossed this time Dan
 
I put my second Libre 2 - on my arm exactly as it says on the tin and put my arms back in my T shirt and cardigan, then started the new sensor. Worked fine between then and sometime this evening, now the reader can't find the sensor. I was really pleased with myself too - cos I unscrewed the cover off the inserter, fresh out of its box comparatively easily whereas for every single prescription one I've had before, including the first Libre 2 a fortnight ago. I haven't had the strength - in my wrists I assume? - to undo them. Clearly ease of opening was not a good sign .... I assume Abbott will replace it but anyway I haven't ordered a repeat scrip yet and was going to do it next Tuesday ......
 
Unfortunately, my latest sensor appears to not be working correctly again. Similar to a previous issue i've had, there's no specific error code in the log, but the readings are consistently and significantly lower than BG when tested. The graph also shows consistent low readings which will very likely be inaccurate.

I'm really not sure what I'm doing wrong. I've applied the sensor correctly after preparation, I've tried the recommended and alternative sites, and I am very careful not to cause water damage, compress, or 'knock' the sensor. Although a brilliant piece of technology, the last 4 sensors used have had a total of approx. 3 weeks use to due errors and inaccurate/unreliable readings.

Is it worth speaking to my local specialist team about how best to resolve, or even look at alternative CGMs (i.e. Dexcom)?

Thank you again for all of your help so far.
 
I’d try sticking the sensor in the place that Abbott recommend. The algorithm is set for that. It is absolutely nothing to do with the reliability of the sensors. That’s assuming you don’t cover the central hole with your various bits of tape.

Abbott won’t replace the sensors if you tell them where you’ve been sticking it. If you don’t, or if you fib, that’s an admission of you doing it wrong. They haven’t written the instructions to annoy people who can’t navigate doors.

Abbott themselves say that it is not approved for sites other than the back of the arm because of the unreliability of readings. You clearly demonstrate their point, so stop doing it wrong. And stop blaming the sensors.

Does that help?

I think this is very harsh and patronising. You've assumed I've always been using unapproved sites for sensors, when i've only resorted to alternative sites because of the exact same issues (and more) with sensors at the recommended site. If readings were consistently reliable with minimal errors where Abbott recommended applying the sensor, I would have no reasonable basis for choosing a different site.

Also, just because Abbott have these recommendations, that's all they are. It does not state clearly in its instructions a large printed warning that this particular site (which is not exactly very specific either) is mandatory for correct use. When I've been applying sensors on the back of my arm since October last year and has resulted in approx. 50%+ failure rate, with multiple bent filaments, compression lows, and damage to skin, I think this far from ideal. Would you agree?
 
I’m on my 5th libre 2 sensor I’ve had a couple of replacements because of the scan error message coming up a lot, and randomly not scanning - I say randomly it’s the same time about midnight ish and for the same lengths of time (24 minutes) then losing data - showing a gap. The replacement are a different lot or batch and are working much better. Teething troubles. I seem to remember similar issues at the start of libre 1. I’ve only ever stuck it to the arm and always the left. It doesn’t feel right on the right. I think they suggest alternating arms
