• Replace faulty sensors
  • Abbott seems to have been replacing them (at least until now)
• Place sensor in a good location
  • About an inch below deltoid on the muscle on backside of arm
  • Not too far down, otherwise shirt cuff rubs sensor

  • Check first day of application
• Allow sensor time to settle in
  • 12 hour warmup may not be enough
• Treat sensor readings as “close enough”
  • Don’t correct for lows without confirming with finger prick

• DIY setups to extend the life of a Libre sensor
  • These setups scan frequently
  • The energy to do the reading comes from the reader - not the libre sensor
  • The sensor lasts 14 days because that’s how long the battery can continue running the part that checks your blood sugar before crapping out
• Device that a third party manufacturer makes
  • Attaches to the sensor and allows connection to the center via Bluetooth
  • Allows the sensor to last 28 days instead of 14 days
• Filament that sits under the skin starts to degrade over time
  • Accuracy degrades when exceeding the FDA’s sanctioned lifecycle
• Scanning the sensor frequently will not reduce data accuracy
  • Can scan up to 300 times in a 14-day period without any issues
  • Can upload data to Libre view software for graphs and charts

  • Reddit user mentioned that they haven’t lost confidence in the system after their sensor malfunctioned, and that it is full of tech and sometimes shit happens.
• Programmer technicians helping to extend the life of diabetic electronic devices:
  • Reddit user mentioned that they are using the Libre to get a better handle on why their glucose readings have been so erratic and what foods are causing that to occur.
  • Reddit user mentioned that they won’t be travelling without their test strips anymore, as it could have had terrible results for a Type 1.
