Arm BG testing sites
 

I have heard that testing on the arm isn't accurate as on the fingers. Is there any truth to this? My fingers are calased and I have to go deeper to get the right amount of blood to test with. Needless to say my fingers are sore. Any advice would be appreciated, Thanks!:(

It is true that the testing in fingers is more accurate. There is about ~15 minute lag time difference when testing from the arm.
