Is my son’s libre faulty? Type 1

Post image

My 12 year old son has cystic fibrosis. His cf team want to check that he isn’t pre diabetic (as this can start in people with CF around his age) We had his sensor fitted by the CF hospital team today at 3pm. I was told to wait a while for it to calibrate before scanning. I have since scanned it a few times to see if it’s working but I keep getting a screen, after the scan complete notification, to replace the sensor.. then it goes back to this screen. Does this mean that his sensor isn’t working, or do I just need to wait a while longer for it to calibrate? The hospital have told me to contact them if there are any issues, but I want to be sure that this isn’t normal before potentially unnecessarily contacting them tomorrow.

My guess is faulty sensor, yeah

Thank you so much, I’ll contact the hospital tomorrow. May I ask, in your experience, are these sensors prone to faults such as this? I only ask as he also has autism, and gets very overwhelmed when any kind of invasive procedures are carried out, and I’d rather ask them if there is an alternative way to do this if that is the case

Honestly yes, sensors are very hit or miss. Sometimes you'll run into a good batch and won't need to replace for several months, and other times they're just bad. 

Can you do something to make the sensors more fun for him? Stickers, robots (if he's interested in that stuff), telling him that the doctors think he's so cool that they want to look at him some more?
