Accuracy of glucometer

I'm not an expert, but this is what I found when searching: You might want to see if your doc will prescribe a new one??


Accuracy Standards for Blood Glucose Monitors

According to the FDA, glucose meter values should be within 15 percent of results obtained from a lab 95 percent of the time, and within 20 percent of lab measurements 99 percent of the time.

Ok, I'm sorry if there is already a thread about this somewhere. My meter consistently reads my fasting blood sugar at around 120 lately. At 6:30 this morning it was 120. About 45 minutes later at the hospital lab it was tested at 102. That is a large difference and makes me wonder if my meter is right. I didn't see what my A1C was but 6 months ago it was normal even though my daily fasting glucose is never under 100! What's up with that?! My doctor is not alarmed but I'm a little confused. Any thoughts?
