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. Put on a new pair of
gloves.
• Select the puncture site at fingertips.
• Rub the puncture site for about 20 seconds before penetration.
• Clean the puncture site using cotton moistened with 70% alcohol
and let it air dry.
• Use a single-use auto-disabling lancing device.
► Fingertip testing
Hold a single-use auto-disabling lancing device
or a safety lancet firmly against the lower side
of the patient's fingertip. Press the release
button to puncture the finger; you will hear a
click indicating that the puncture is complete.
• Choose a different spot each time you test. Repeated punctures at the
same spot may cause soreness and calluses.
• It is recommended to discard the first drop of blood as it might contain
tissue fluid, which may affect the test result.
