I inserted a new sensor 3 days ago and the first day or two the readings were pretty good, about 8-10 points lower than my meter. However, since yesterday they have been really off, 40+ points lower than my meter today, showing me 67 when meter said 110! I’m not sure what might be causing this as nothing else seems to have changed from the first couple of days. I’m wondering if it’s because the sensor expired on June 30th? I’m not entirely sure what it means for the sensor to expire. Like the chemicals in the microfluidic channels expired and can no longer measure correctly? Any ideas of what might be causing this? Should I take it off?
Thanks for any suggestions.
