Preparing the Puncture Site
Stimulating blood perfusion by rubbing the puncture site before blood
extraction has a significant influence on the glucose value obtained.
Blood from a site that has not been rubbed exhibits a measurably
different glucose concentration than blood from the finger. When the
puncture site was rubbed prior to blood extraction, the difference was
significantly reduced.
Please follow the suggestions below before obtaining a drop of
blood:
• Wash and dry your hands before starting.
• Select the puncture site either at fingertips or another body parts
(please see section “Alternative Site Testing” (AST) on how to select
the appropriate sites).
• Clean the puncture site using cotton moistened with 70% alcohol
and let it air dry.
• Rub the puncture site for about 20 seconds before penetration.
• Use a clear cap (included in the kit) while setting up the lancing
device.
