Why do we need to prick our fingers for glucometers. Can we get blood from some!
Question:
Why do we need to prick our fingers for glucometers. Can we get blood from somewhere else on the body?
I don't know if it's for convience or because the blood through our fingers has the most accumulation of glucose because of where it's siutated relative to the heart, but why can't we prick another part of our body that is less sensitive than our fingers to get blood for a glucose test? Blood is blood right? And there should be the same percentage of glucose through our bodies regardless if we measure it at our fingers or blood from our arms. Does anyone have a good answer? Thanks!
Answers:
the vessels are shallow in the fingers with no risk of hitting a major artery.
