In particular, if blood glucose levels are changing rapidly — as would be expected after a meal, after an insulin injection, or during exercise — there may be a significant difference in the blood glucose level measured in a fingertip sample and in an alternative site sample. Therefore, using a fingertip sample is recommended if you are monitoring at these times."

Better source, WebMD: > "When the amount of sugar in the blood was rising or dropping rapidly, only the finger prick testing accurately caught these rapid changes. It took about 30 minutes for the forearm values to catch up to those reported by the finger prick tests."
