Hi one and all, getting towards the end of the Libre sensor finish date and which give reading some way off the reading I get from both my Accu-Chek expert and the test strips for the Libre with reading about ,in some cases 3 points difference ;such as the Libre giving 5.7;the Accu-Check giving 4.9 and their own test strip giving 6.7. Pity the strips are not giving a more accurate glucose level as I do not know who to beleave?
