Message: <blockquote data-quote="Deleted member 527103" data-source="post: 2534975">Sorry to read of your issues. However, please bear in mind that CGMs are not accurate at low levels. With my experience of multiple different types of CGM, I would never take a 54 (3.0) on a CGM as gospel. If the CGM alerted me to the low, I would check with a finger prick. I don't know what type of CGM you are using but I always try to calibrate my sensor to me (using a finger prick). Unfortunately, the cheaper CGMs such as Libre do not allow this so I "mentally" calibrate the readings: I compare the CGM readings with a few stable non-hypo finger prick readings and add/subtract the average difference for future CGM readings. It is not uncommon for people to find Libre under reading by a unit or more. My (unconfirmed) hypothesis is that some of us are different to the "factory man" they use for factor calibration. I hope your doctor helps you get to the bottom of your problems.</blockquote>
