Whilst I've been using the Libre, on occasions, for various reasons, I've thought the reading doesn't seem quite right, so I waited 10mins then took another reading and when that reading was the same, or very similar, I also did a BG test. These are all after 48hrs of the sensor being in, I consciously try and keep myself hydrated so that shouldn't be an issue. These are the results, notice how all of them have a horizontal trend arrow.
What do people think? Are these results typical to what others have been experiencing?

I had exactly the same with my first sensor. It meant I had to keep blood testing as I couldn't trust the scan. This one seems a little better but still off compared to the Mobile sometimes. The trouble I had was that I didn't have any Optimum strips so I couldn't know for sure if the sensor, Mobile or both were out. Abbotts offered to replace the sensor and also sent 10 test strips so that I could check the meter at the same time as the scanner - the meter was almost always within a couple of points of the Mobile while the scanner was frequently wildly out. It was obviously not just the time lag as I was once 2.9 on the meter and high 5s something on the scanner with a horizontal arrow.
I had a very long call with them about the horizontal arrow. It means your BG is moving at less than 0.1 mmol per minute - it doesn't mean your BG isn't changing. They went through my data in detail as I was concerned that my BG had drifted one evening from around 6 to around 10 and it never showed anything other than a horizontal arrow. The Abbotts rep said they hadn't had any other calls regarding that and he thought my BG was moving too slowly to register the direction as it only compares to the last minute. He recommended scanning more frequently as this might catch the slight changes. I still see very few of anything other than horizontal arrows even when my BG is rising or falling, but looking at my data, my BG really does seem to drift rather than move quickly. Anyway, you should report it to Abbotts so that they start getting a log of this type of issue. Everyone is reporting the inaccurate sensors, but we need to report other issues as well.
