I've just posted this on another thread, but desperate for some insights. I'm a first time poster here (or I was a few minutes ago)
My son is 6 years old, diagnosed T1 in November 2018, and has been using the FS Libre for nearly 3 months now. Up to now they have generally been fine. On Thursday we changed the sensor 3 times, and the readings were 2-3 mml different to the blood prick readings. On the first one, we put it into the side of his arm and not the back. I read somewhere that if it goes into a muscle it will be inaccurate. So we changed it. The second one, there was a bleed when we applied the sensor, so we thought it was because of that. So we put a third one on, another bleed and again a difference of 2 to the blood test. We called Abbott and they suggested waiting 24-48 hours, after a bleed. So we are waiting, while in the meantime, can’t send him to school and expect teachers to do blood tests instead using a simple scanner. (Before anyone calls social services - He does have a careplan, and we and school keep to it rigidly, but we rely on the libre to make it work. DS's teachers are trained in doing blood checks but we don't want to drive him mad.)
Have any of you ever had this experience? Firstly, how common is it to bleed when applying the sensor? Secondly, does a bleed affect the accuracy of the sensor? And, if bleeding does not affect it, we had three different sensors giving wild results!!
The thing that is confusing us here, is that we've used probably 5 or 6 sensors to date, and they've all been fine. Now suddenly, we have 3 that are faulty?! For us, we don't want to finger prick a 6 year old constantly, the libre has been a lifesaver, but now we feel we are driving on a dark road without any lights, as we are giving food and don't know for certain where his levels are.
