I was researching an answer for a question by mewElla about different readings from different hands and came upon an article about it. I learned something new.
There is a difference between the SIDES of the finger and the PADS of the fingers, but not a serious difference between fingers. There IS a difference between, say, your finger tips and your forearm. Some meters will account for this, most older meters do not.
ALSO, you are instructed to NEVER use the first drop of blood from you finger. Always squeeze one drop, wipe it off, then use the SECOND drop. The first drop, being "closer" to the surface, has most of the sugar used up. The SECOND drop, being from the vein, had a more accurate reading.
HOWEVER, there is also a normal, expected difference of about 20 points between each individual test strip! That is, if you were to take a reading, of say 95 with one test strip, then immediately do another second reading, using blood from the same wound, on a second test strip, the second reading might be anywhere between 75 and 115.
