I wonder if anyone else has tried this or
knows why ...
BS in the finger is 6.0 cdn
in the arm 7.8 or
8.3 in finger
10.2 in arm or

7.6
It always seems to be higher in the arm.
Any ideas?

I have been told that the finger is always
the most accurate location because it
reflects changes quicker. I'm not sure
why, but I believe it is because of the
type of blood vessels there. We use the
forearm most of the time for my 8-year-old
son. His endo told me that the forearm
numbers will lag behind what the finger
would show. Therefore, it you are at a
time when the BG is quickly changing (like
after eating or after giving a bolus or
injection of insulin), the finger is your
best bet. If it has been a while since
you've done anything to change your BG,
the forearm should be fairly accurate. So
it's possible your BG is dropping at the
time you're checking and that is why the
finger shows a lower number.
