(In general, guidelines advise against squeezing the finger too hard to get a blood drop because it may distort blood sugar readings.) Overall, the study found, clean hands are still key.

Why do you get different blood sugar readings on different fingers?

Contamination of the fingers is a common culprit in blood sugar reading variability. That’s because it only takes a little bit of food residue on your hands to impact blood glucose levels. For example, just touching a banana or cutting a piece of fruit can send your numbers sky high.
