Fear not, it isn't full of congealed blood. I was at swimming today and I'd cleaned it anyway. From the look of Google it's happened a few times and apparently it doesn't interfere with the operation of the sensor.Somebody posted here that he showered when that happened and flushed that hole out. I don't know what it's for, but is meant to be a hole and not full of congealed blood.
IMHO it is a lot less painful than a single finger prick test. You do not put a needle in an out - there is a spring loaded device that you apply and it presses on for you and just guides it in. I honestly never feel any more pain than a small finger prick and it is only once every 14 days and not 10 times every day.I get that it works for you, but I am not so brave! Reading what you have just written just makes me feel worse. So you have to pull the needle out as well as push it in??? And then there is a filament IN ME!!! NO WAY! Makes me feel finger pricking is almost enjoyable by comparison. But thanks.
Got to agree. Before I was converted to Libre I'd had a couple of seriously high , unexplained jumps and I was having to do a lot....and I mean lot of testing. My poor fingertips were a mess. Libre was a relief and gave my fingertips a rest.IMHO it is a lot less painful than a single finger prick test.

Well despite the bleed through the sensor, I'm glad to say the out of date sensor activated no problem. I've carried out my first comparison and it is measuring 1.4 under the finger prick at 15 mins. However, my BGs are currently falling and I have found with Libre that there tends to be a wider gap when they are on the fall. Will be carrying out more checks over the next 2 days.Well my experiment starts tomorrow. I applied the last sensor that expired on 31 August and it is due for activation tomorrow. The one I am currently wearing also expired 31 August but was applied before the expiry date which is fine according to Abbott. To be honest it has been a good sensor only measuring 0.4/0.5 under the finger jab at 15 mins. I'll do a few checks when I activate the new 'out of date' sensor just to be sure. If it fails I do have a new batch.

Latest checks and it is still sitting 0.5 under so I'm happy it's settled and that is acceptable to me.Latest check and it is 0.5 under. Seems to be settling.

And we're still 0.5 under. This out of date sensor is doing fine.Latest checks and it is still sitting 0.5 under so I'm happy it's settled and that is acceptable to me.

I have said it before, I love the Libre for convenience, but accuracy? I'm seriously thinking of quitting using it. Yesterday I had a period of inexplicably high BG, and the meter to Libre discrepancy was nearly two! The meter being the higher, but earlier in the day while in range the difference was about one, and the other way
Coincidentally seeing my consultant today so will discuss pro/cons of potential better control against accuracy with her.
0.5 of a difference is pretty good for the Libre. My current sensor is around that level. I've had them 2 under but as long as you know roughly where it is sitting you can work with it. I tend to jab 3 times a day and scan at 15 mins after. Only time I scan extra is if I get a weird reading. For example I got a 3.2 recently with a downward arrow which was enough to make me check. It wasn't 3.2 - it was 4 so it was low but not as low as Libre thought. It seem when it is very low or very high in a rapid change you get a bigger gap.Just started using my first sensor. Already loving the freedom to test whenever without having to take time out and go somewhere to test. Quite happy to just do it at my desk now.
Accuracy is a bit of a concern at the moment - my Tee2 is saying 5.4 while Libre is holding steady at 4.9 10 minutes after, which seems like a bit of a difference to me. From this thread though it seems like it might settle down after a couple of days? Looks like I'll be doing some confirmatory testing for a while
Have just had my third sensor of 5 fail - it's over 5 mmol out against finger pricks. According to libre I was at 2.9 and dropping but I was really 8 and rising. The libre never went above 3.8 for the next 5 hours though I went up to 11 having started to treat the 2.9 instead of double and triple checking with other meters. Not sure I will be buying again as they can't seem to explain it not that they really try. It does seem to go wrong more in my left arm than right...0.5 of a difference is pretty good for the Libre.

The really low readings are annoying as it comes up as low glucose events which of course it isn't.
I always apply mine 2 days before I activate it. It really didn't like being activated straight away.
You should have got Abbott to replace it - that's well outside their parameters. You've certainly been unlucky. They've replaced 2 of mine no problem.Have just had my third sensor of 5 fail - it's over 5 mmol out against finger pricks. According to libre I was at 2.9 and dropping but I was really 8 and rising.

In discussion with them, they have replaced the previous 2 but I think I have reached the point where I would rather they gave me a reason. I have sent them all back but no feedback. I work with GPs and we were discussing the libre and I was honest and said great for trends and when it works there is nothing better but it's reliability does seem to be in doubt. None of my sensors started as failures and all developed problems at different times which in some ways made the failure worse as I believed it was accurate until it was clear my levels weren't rising even though I had eaten carbs etc. It doesn't appear to be position on arm, I'm not sleeping on it, I've tried it covered and uncovered. So far the only thing is that the last 3 have all failed on my left arm. If I get this one replaced I will put it on my right arm even though that's where the current one is and see what happens. I also wonder whether or not they have had a few dodgy batches as the first few I used were fine.You should have got Abbott to replace it - that's well outside their parameters.

What I find with them is so long as I apply them 2 days before activation then they run pretty close until the last few days then the gap widens but not usually more than 2 under.In discussion with them, they have replaced the previous 2 but I think I have reached the point where I would rather they gave me a reason.

So perhaps what I am seeing is a normal pattern but exaggerated for some reason.What I find with them is so long as I apply them 2 days before activation then they run pretty close until the last few days then the gap widens but not usually more than 2 under.
Current one went from 0.4/0.6 to 1.4/1.8 and now back to 0.8! I do about 3 checks a day anyway but I've done a few more in the last few days as I've been getting readings in the 2's and 3's on the Libre (was actually low 4's). Thankfully I change over tomorrow so hopefully I'll be back to a closer reading for a week or so.
