How much is normal for the Dexcom to be off from the BG meter? I
just started my very first sensor yesterday so I am still in the
first 24hours, but it seems like the sensor readings are 20
points or more off of my meter results. Does it help to continue
entering meter readings to the dexcom to help it be more
accurate? Or should I just do the 2 per day and hope the
accuracy improves? Any help is greatly appreciated.  Laramie, WY

things settle in and they are pretty accurate. But, I've also
had several sensors also be totally accurate from the start,
too. So, I think it just depends. But I think general consensus
is to expect a bit of inaccuracy in the first 24 hours. Some
people say that if you start up a sensor when your blood sugars
are relatively stable, then
