I have just downloaded my first five days' data from my Libre and analysed the differences between the meter readings I have taken with my Accuchek meters. For the first 16 hours or so, the sensor obviously wasn't working properly. When I did the first test, it was bang on the same as my meter reading but then it all went pear shaped overnight, refusing to budge off "low", and on at least one occasion not giving me a reading at all. I went to bed very disappointed with it. However, next morning was a different story!
I've exported the results and put them in a spreadsheet so I could add my meter readings in order to compare them, and if I ignore those first 16 hours, the average difference between my meter readings and my Libre is 0.39. The maximum is 2.3 and looking at the data I can see that this was a time where my blood sugar was increasing rapidly after treating a hypo - the reader took a little while to catch up.
I am very happy with this. I am also elated to see just how little my blood is spiking after meals. I had given up testing after meals because I didn't seem to be able to prevent spikes but now I see that apart from breakfast, where I think I may need to adjust my morning basal a little, I'm not getting spikes at all.
The readings have also quite clearly shown me that my dawn phenomenon is alive and kicking - I thought it had gone because my waking levels were behaving themselves - it is happening between getting up and having breakfast - what I think I've seen called the "feet hit the floor phenomenon". That's really useful to know because it means I can adjust my basal on weekdays to compensate.
I bought the starter pack with two sensors with the idea of using them to do my basal tests every now and then, but I am so liking the reduced finger pricking and the ability to know what my levels are doing as often as I like, that I am very tempted to use them continuously, even at the cost of nearly £100 a month. I'll see how I feel once I've got all my basal pump settings working.
I have had a problem with the reader - the touch screen doesn't work properly, but Abbot are sending me a new one. It doesn't prevent me using it, just means I can't scroll back on menus and I have to press some of the buttons a few times to get them to work. Does anyone know whether I'll be able to use the new reader with the existing sensor, or will I have to wait until I change the sensor?
