Preparing the puncture site
Stimulating blood perfusion by rubbing the puncture site prior to
blood extraction has a signicant inuence on the glucose value
obtained.
Blood from a site that has not been rubbed exhibits a measurably
different glucose concentration than blood from the nger. When the
puncture site was rubbed prior to blood extraction, the difference
was signicantly reduced.
We recommend you perform disinfection procedures between each
patient. Please refer to the section Cleaning and Disinfection Pro-
cedures for complete instructions. After disinfection, used gloves
should be removed and hands washed before proceeding to the
next patient.
Please refer to the following practice guidelines for more information
about the correct procedure:
