Preparing the Puncture Site
Stimulating blood perfusion by rubbing the puncture site prior to 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 is rubbed before blood extraction, the difference is
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.
