How to increase the accuracy?
Stimulating blood perfusion by rubbing the puncture site prior to blood extraction has a significant influence
on the glucose value obtained. Blood from the site without rubbing exhibits a measurably different glucose
concentration than blood from the finger. When the puncture site was rubbed (20 seconds) prior to blood
extraction, the difference was significantly reduced.
