That's absolutely nuts! Have you sent that to Abbotts to see what they have to say about it? I just get horizontals most of the time regardless of what my BG is doing.

......Now accuracy as of NOW, scan reading. Fasting, no rapid insulin. All 3 sensors that I've used,once settled, pretty much showed 1mmol low and 20 minutes behind a finger prick. I can almost trust this. Unfortunately I do not live fasting and no insulin.

So. When my glucose levels are rising - be it food, high gi or low gi or be if dawn phenomena, the scan lags behind the rise and the differnce between the two increases. Then, as the insulin bites my BG peaks and starts to drop - while the scan is lagging and still rising. They get closer and after 30 or 40 minutes the scan gets to read higher than the BG - they cross and can be identical.......

Unfortunately this is the case for every cgm system currently on the market due to the lag in glucose concentrations in capillary blood vs interstitial fluid.
 
Hi all,

So I took the plunge and bought one - justified it as I need a second monitor anyway, and already get the compatible strips on prescription.

put it on 5th rs ago, everything reading a few mmol low. I.e. I was 4.8 by blood it said 2.2, then 4.2 by blood, some lows or > 3 by sensor when Iin 5-6 by blood. Last reading by blood was 5.8 and scan 2.7.

did most people experience a day settling or can I expect it to be this far out? It isn't much use with current levels coming up so low and out.

Thanks,
J

Hello
A few of us, including me, found it took a few days to settle. Abbott told me it's because ur arm is effectively treating the foreign object as an injury and sending fluid to it. After a day (or 3) it should settle and each time will settle quicker :)

Yes, many. It took mine three days to settle, both times. Annoying, but it's still valuable for the timing/trends, and then after the three days is much more useful.
 
FYI Anyone who like me ordered on day 1 and has tomorrow on change over day... We are on course to change over on New Year's Eve if we carry on in the same pattern.
Just an FYI really. Prob better to try to switch out to Thursday at some point over the next few weeks
 
Thanks for the replies. I was wanting to use it from today as ijust had a steroid injection and barbotage in my shoulder today so want to see the effects of it on my bs too. I'm just pricking more though ;)

So do people generally insert their new sensor 1-2d earlier than activation to overcome this?

Also, has anyone investigated high intakes of salicylates for example to see the effects?!

Thanks!

Just as well I knocked my first one off a day early - I'll be swapping on new Years Eve Eve. I'm going to pretend that was my plan all along LOL!

I didn't put my second one in early, and worked quite quick. Next swap over is tomorrow so will report back then
 
Should we accept that the sensor may take 2, 3, 4 or more days to 'settle in' when Abbott say that over a 14 day period there is no change in accuracy? - apart from the first day that is!

In the video link Abbotts' Jared Watkin (Divisional Vice President - Technical Operations) appears to condradict himself by first saying that for signal stability they see no change in response over the 14 days the sensor is in the body (12:23). He then goes on to say (14:23) that over the 14 days "apart from the first day" there is no change in accuracy. Hang on!! 14 - 1 = 13. Also the graph that he uses (which omits the first day) shows that the second day is not as accurate as the following days. So their own presentation shows there MUST be a change in response and the signal is not stable over the 14 days.

One figure that shocked me was the number of people they engaged to make the accuracy claims (12:47) and that is 75 - yes ONLY 75!

I suspect that peoples' interstitial fluid varies far more than they expected and while the sensors' factory calibration is spot on for many people it is way off for many others.

Thanks. I didn't know that. I'd have been a lot quieter had I known.

I'm entirely self taught, the NHS don't cater for type 2s graduating onto insulin. I think we are supposed to die before we get to that stage.

LOL - well the NHS has to save money somehow - killing off T2's before they get to be T1's would be one way of doing it I suppose :dead:
 
Well, I put my 3rd sensor in earlier and it is reading almost spot on at the moment - although I think my 2nd one was OK for the first couple of days surprisingly and then deteriorated. This is the first I've used from a different batch. This one is the one Abbotts sent me as a replacement for the first dodgy one. Unfortunately, the two I've since bought which are still in their boxes are from the original batch. So we'll see how this one goes.

Incidentally, I still haven't received the replacement senor they've promised for the second dodgy sensor - it's been a week and it hasn't even shown up on my account. I rang them earlier (my daily Abbotts phone call) and they said they didn't know why it hadn't been sent but would look into it and get back to me by the end of the day. Guess what my Abbotts phone call tomorrow will be about!

@logindetails, I'm not surprised at that number. In an earlier post I noted that the sample size on which they quoted skin irritation statistics was only 30 people. While you *can* extrapolate data from small sets, the reality is that for a product that could be used by millions, these are laughably small sample populations that are practically statistically irrelevant.

Welcome to the world of medical testing and clinical trials.

Hi Emmotha, did you replace the new sensor into the same arm/site area?

Hi jddukes, I think they recommend alternating arms to let it heal properly when you remove a sensor. I'm on my third sensor and have gone back to the first arm but in a slightly different site.

I swapped arms. Tomorrow I'll swap back but in a different spot. Trying to work out the best place to avoid laying on it at night and walking into stuff etc. I'll put it on as I take this current one off
 
Just found this fab forum. I have learnt so much. My first sensor finished this evening and I felt bereft. I want to ration mine if I can, but already post sensor, I have dropped to 3.2. (Carb guess being the issue)
I have used the readings as an indication, put the data into my Omnipod, for calculations, and had the most amazing success with mainly in target readings, instead of soaring up and down. I changed my Omnipod settings after a few days. If data was going low or high, I used the Omnipod meter too, if not, I didn't need to bother much. I don't find the data entry on the LIbre very useful or necessary for me, even though I used the professional bit to enable me to add insulin in half units.
Today I zapped it at my golf club and the people at my table, asked me to zap them to get their blood sugar!

there isn't a reason you can't put it on your belly, bum or mammary is there?
