[QUOTE="maglil55, post: 1628022, member: 52911"] No, I wouldn't say finger pricks are more accurate just that they are giving you a reading at that point in time from blood. The sensor is different as it measures interstitial fluid and runs (according to Abbott about 10-15 mins behind the blood measurement). So you expect a difference - just not one that is wildly different. You do get the odd 'rogue' reading (I find usually during a period of rapid change) which is well out from a finger prick. The difficulty I had initially was separating an odd 'rogue' reading from a dodgy sensor (fortunately I've only had 2 dodgy sensors both of which were replaced by Abbott without question). In case you are wondering 'dodgy' was measuring low 3's and 2's one minute and high 10's the next whereas I was more like mid 4's to low 5's. It has been invaluable for identifying what I can and can't eat but that is personal to me. I am well aware that others can tolerate foods that I cannot go near. A prime example was porridge which sends my BGs through the roof and for a long period. Another no no is potatoes in any form and regrettably a lot of pulses. I used to eat around 100g of the so called 'good' carbs but this was too high for me. I lowered it to 40g daily but now I aim for 20g or less. So long as I am not ill this level is enough to keep my BGs in the 4-5's (illness sends it up regardless). It would have taken me a long time to work this out with finger jabs but as I said this is what suits me and may not suit another person although life would be a lot easier if we were all the same.
