Event Description
The accuracy and reliability of the free style libre 14 day sensor is suspect especially after 10 days. I have noticed the scan reading and the finger stick reading can be up to 80 units off. I have seen it from 2 days after applying to 10 days after applying before the discrepancies. The company only offers a replacement. Typically i have taken the finger stick and compared to screen readings when the screen reading show a steady level. Not all sensors failed but a majority of them do. Also, my skin does not allow for the sensor to stay on especially when humid and i am working outdoors. Based on the scan readings, i do not take medicine which shows high a1cs. Fda safety report id# (b)(4).
