First gluco check was done on left hand index finger, 314. VERY high for resident. After joking with her that I would do a recheck on her right pinkie finger because maybe it would be lower (because the finger is smaller), 145. normal for resident.
Why such a difference?
I used the same type of test strips, same glucometer, same type alcohol swabs.
Only thing I can think of is maybe I didn't clean her finger off good enough and there was some food or something left over that was picked up in the high reading.
