Incorrect insulin dose.I recently started using the freestyle libre 14 day glucose monitor.Two of the first 4 sensors were defective as determined by abbott.Abbot replaced them.I have spent hours on the phone with abbott and the problem is on their end.Glucose readings on this monitor are significantly lower than readings using the standard finger stick meter.The problem of low readings on the glucose monitor is widely reported on the internet.It was also reported to me by my diabetic supplies company.The low readings cause an incorrect insulin dosage (too little insulin) resulting in higher than desired blood sugar levels.At this point, this system should not be used for insulin dosing.Fda safety report id#: (b)(4).
